## **Matters to Be Observed When Using This Product** 

(Chip-type laminated varistor) 

## **Safety measures** ~~a~~ 

- A chip-type laminated varistor (hereinafter “the product” or “the varistor”) is intended for use in general-purpose and standard applications, such as electrostatic control/noise suppression, in general electronic equipment (AV products, household appliances, office equipment, information/communication devices, etc.). The varistor may deteriorate in performance or fail (short or open mode) when used improperly. 

- If the varistor in short mode is used, applied voltage may cause a large current to flow through the varistor. Consequently, the varistor heats up and may burn the circuit board. An abnormal state of the varistor that results from a problem with its service conditions (use environment, design conditions, mounting conditions, etc.) may lead to, in a worst case scenario, burnout of the circuit board, serious accident, etc. Sufficiently check for what is described below before using the varistor. 

## ~~Pe~~ **Use environments and cleaning conditions** 

- This product (varistor) is not designed for use in the specific environments described below. Using the product in such specific environments or service conditions, therefore, may affect the performance of the product. Please check the performance and reliability of the product first and then use the product. 

   - (1) Used in liquid, such as water, oil, chemicals, and organic solvents. 

   - (2) Used in a place exposed to direct sunlight, an outdoor place with no shielding, or a dusty place. 

   - (3) Used in a place where the product is heavily exposed to sea breeze or a corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX. 

   - (4) Used in an environment where electromagnetic waves and radiation are strong. 

   - (5) Located close to a heating component or a flammable material, such as a vinyl cable. 

   - (6) Sealed or coated with a resin, etc. 

   - (7) Solder flux of the soldered product is cleansed with a solvent, water, and a water-soluble cleaner (be careful with solder flux soluble to water). 

   - (8) Used in a place where dew concentrates on the product. 

   - (9) Used in a contaminated state. (Example) Touching a varistor (with uncovered skin) mounted on a printed board leaves sebum on the varistor. Do not handle the varistor in this manner. 

(10) Used in a place where excessive vibration or impact is applied to the product. 

■ Use the varistor within the range of its specified ratings/capabilities. Using the varistor under severe service conditions that are beyond the specified ratings/capabilities causes degraded performance or destruction of the varistor, which may lead to scattering of varistor fragments, smoke generation, ignition, etc. Do not use the varistor at a working 

temperature or maximum allowable circuit voltage that exceeds the specified working temperature or maximum allowable circuit voltage. Do not locate the varistor close to combustible materials. 

- In an improper cleaning solution, with which the varistor is cleaned, flux residues or other foreign matter may stick to the surface of the varistor, which degrades the performance (insulation resistance, etc.) of the varistor. In a polluted cleaning solution, the concentration of free halogen, etc., is high, and may result in poor/insufficient cleaning. 

■ Improper cleaning conditions (insufficient cleaning or excessive cleaning) may impair the performance of the varistor. 

- (1) Insufficient cleaning 

   - (a) A halogenous substance in flux residues may corrode a metal element, such as a terminal electrode. 

   - (b) A halogenous substance in flux residues may stick to the surface of the varistor and lower its insulation resistance. 

   - (c) Tendencies described in (a) and (b) may be more notable with water-soluble flux than with rosin-based flux. 

Be careful about insufficient cleaning. 

- (2) Excessive cleaning 

Ultrasonic waves that are too powerful from an ultrasonic cleaner cause the board to resonate, in which case the vibration of the board may cause the varistor or a soldered part to crack or reduce the strength of the terminal electrode. Keep power output from the ultrasonic cleaner at 20 W/L or lower, its ultrasonic frequency at 40 kHz or lower, and an ultrasonic cleaning time at 5 minutes or less.

**Matters to Be Observed When Using This Product** 

## **Response to anomalies and handling conditions** 

- Do not apply excessive mechanical impact to the varistor. Because the varistor body is made of ceramic, drop impact to the varistor readily damages or cracks the varistor. Once dropped on the floor, etc., the varistor may have lost its sound quality and become failure-prone. Do not use said varistor. 

- When handling the board carrying the varistor, be careful not to let the varistor hit against another board. Take extra caution when handling or storing a stack of boards carrying varistors. There are cases where a corner of a board will hit against a varistor and damage or crack it, which may result in a failure of the varistor, such as a drop in its insulation resistance. Do not reuse a varistor that has been used on and removed from a board.

## **Reliability** 

To know the detailed specifications of individual products or specific evaluation test scores, please contact us. We issue a delivery specification sheet for each product ordered. Please confirm with the sheet when you place an order with us. 

## **Circuit design and circuit board design** 

- A working temperature at which a varistor works in the circuit must be within the working temperature range specified in the specification sheet. A temperature at which a varistor incorporated in the circuit is kept in storage without operating must be within the storage temperature range specified in the specification sheet. Do not use the varistor at a higher temperature than the maximum working temperature. 

- Keep voltage applied across the terminals of the varistor equal to or lower than the maximum allowable circuit voltage. Applying improper voltage to the terminals may cause the varistor to fail or short-circuit thus generate heat. When using the varistor in a circuit where high-frequency voltage or pulse voltage of an acute waveform is applied consecutively, even if the applied voltage is lower than the rated voltage, confirm that the varistor is reliable enough to operate normally in the circuit. 

- Ensure that the surface temperature of the varistor, which includes a temperature increment resulting from self-heating, is equal to or lower than the highest working temperature specified in the delivery specification sheet. Check the temperature of the varistor under the circuit conditions used in the operation state of the device in which the varistor is incorporated. 

- Using the varistor on an alumina board has an expectation of performance degradation due to thermal impact (temperature cycle). Before using the varistor, sufficiently confirm that the board does not affect the quality of the varistor. 

## **Mounting conditions** 

- The more solder deposited on the varistor, the greater the stress to the varistor, which leads to cracking of the varistor. When designing a land on the board, determine the shape and dimensions of the land so that a proper volume of solder is applied in the land. Design the land such that its left and right sides are equal in size. In a case where solder volumes are different between the left and right sides of the land, a greater volume of solder takes more time to cool and solidify. As a result, stress acts on one side which may crack the varistor. 

## <Recommended solder volume> 

(a) Too much solder  (b) Proper volume of solder  (c) Too little solder

<Using solder resist> 

<Varistor placement that avoids stress caused by warp in the board> 

<Mechanical stress near a breaking line of the board> 

- ・ The varistor receives mechanical stresses different The varistor receives mechanical stresses different in size when the board is broken by different methods. The size of the stress the varistor receives is smaller in the following order: pushing back<breaking along a slit<breaking along a V groove<breaking along a perforated line. In addition to varistor placement, consider the board breaking method as well. 

<Mounting density and space between components> 

- ・ When space between components is too narrow, solder bridges or solder balls have negative effects on the components. Be careful to provide proper space between the components.

**Matters to Be Observed When Using This Product** 

## <Mounting on the board> 

- ・ When the varistor is mounted on the board, an excessive impact load, such as pressure from a suction nozzle for mounting the varistor and mechanical impact/stress caused by a positional shift or positioning, may be applied to the varistor. Prevent application of such an excessive impact load to the varistor. 

- ・ A mounter needs to be checked and maintained regularly. 

- ・ When the bottom dead center of the suction nozzle is too low, an excessively large force is applied to the varistor when it is mounted, which may crack the varistor. Heed the following instructions when using the suction nozzle. (1) Set the bottom dead center of the suction nozzle at the upper surface of the straightened board. 

   - (2) Set the pressure of the suction nozzle equal to a static load between 1 N to 3 N. 

   - (3) In the case of double-face mounting, put a backup pin on the lower surface (back) of the board to prevent the board from warping. This keeps the impact of the suction nozzle as small as possible. Typical examples of using the backup pin are shown in the following table.

   - (4) Adjust the suction nozzle so that its bottom dead center is not too low. 

- ・ When positioning grippers wear out, they apply mechanical impact to part of the varistor when positioning it, thus chipping or cracking the varistor in some cases. Maintain the proper dimensions of the positioning grippers in their closed state and regularly carry out maintenance, check, or replacement of the positioning grippers. 

- ・ A varistor mounted on a heavily warped printed board, may crack or break. Put a backup pin on the back of the board to reduce the warp of the board to 0.5 mm or less with 90 mm span width. 

## <Selecting flux> 

- ・ Flux may have a great effect on the performance of the varistor. Before using the varistor, check whether the flux has any effect on the performance of the varistor. 

## <Soldering> 

- ・ Flow soldering 

In the flow soldering process, stress created by a sharp temperature change is applied directly to the varistor. Be careful, particularly, in controlling the solder temperature. The varistor is particularly vulnerable to rapid heating and rapid cooling. When heated or cooled rapidly, the varistor develops excessive heat stress therein resulting from the large temperature difference and because of this heat stress, may thermally crack. Observe the following instructions on preheating, gradual cooling, etc. 

- (1) Applying flux ：Apply a thin and uniform film of flux to the varistor. In the flow soldering process, flux application by a foaming method is generally adopted. 

- (2) Preheating ：Preheat the varistor sufficiently so that the difference between the solder temperature and the surface temperature of the varistor is 150 or less. 

- (3) Immersion in ：Immerse the varistor in melted solder of 240 to 260 in a solder bath for 3 to 5 seconds. 

## solder 

- (4) Gradual cooling ：Avoid rapidly cooling (forced cooling) the soldered varistor, instead cool it gradually. 

- Rapidly cooling the varistor may result in thermal cracking of the varistor. ℃ 

- (5) Cleaning ：When dipping the varistor in a cleaning solution right after soldering the varistor, confirm that the surface temperature of the varistor is 100 or lower.

Avoid performing rapid cooling (forced cooling) during the gradual cooling part. Rapidly cooling the varistor may result in thermal cracking of the varistor. When dipping the varistor in the cleaning solution right after soldering the varistor, confirm that the surface temperature of the varistor is 100 ℃ or lower. There is no problem with two cycles of reflow soldering under the recommended reflow soldering profile (example) conditions shown in the above diagram. Be sufficiently careful with deflection or warping of the board. 

Note that the recommended soldering conditions indicate conditions under which the degradation of the product characteristics does not occur but do not indicate conditions under which stable soldering can be performed. Check and set conditions under which stable soldering can be performed, on a case-by-case basis. 

Varistor temperatures vary depending on the mounted state of the varistor. Make sure to confirm that the surface temperature of the varistor is within the specified temperature when the varistor is mounted and then use the varistor.

## ・ Soldering-iron-used soldering 

In soldering-iron soldering, stress created by a rapid temperature change is applied directly to the varistor. Be sufficiently careful in controlling the temperature of the soldering iron tip. Be careful not to let the soldering iron tip come in direct contact with the varistor or its terminal electrode. 

The varistor is particularly vulnerable to rapid heating and rapid cooling. When heated or cooled rapidly, the varistor develops excessive heat stress therein resulting from the large temperature difference and because of this heat stress, may thermally crack. Observe the following instructions on preheating, gradual cooling, etc. 

Once a varistor soldered with a soldering iron is removed from the board, it cannot be used again. 

- (1) Condition 1 (preheating included) 

   - (a) Solder: ：Use wire solder (with less chloride content) that is meant for soldering precision electronic equipment. 

      - (Wire diameter: 1.0 mm or less) 

   - (b) Preheating: ：Preheat the varistor sufficiently so that the difference between the solder temperature and the surface temperature of the varistor is 150°C or less. 

   - (c) Temperature of ：300°C or lower (a required volume of the soldering solder is melted on the soldering iron tip iron tip in advance).

- soldering-iron tip, slide the soldering-iron tip toward the terminal electrode of the varistor to solder the varistor. 

## <Inspection> 

- ・ When the printed board is inspected with measurement terminal pins after the varistor is mounted on the board, the measurement terminal pins pressed against the printed board cause the board to warp, which may cause a crack to form on the varistor. 

   - (1) Put the backup pin on the back of the printed board to reduce the warp of the board to 0.5 mm or less with a 90 mm span width. 

   - (2) Check whether the shape of the front ends of the measurement terminal pins poses no problem, whether the pins are equal in length, whether the pressure of the pins are not excessively high, and whether the set position of the pins is correct.

## <Protective coat> 

- ・ When the varistor is coated with or embedded in a resin to improve the varistor’s resistance to humidity and gas or to set the varistor stationary, it is expected that the following problems will arise. In such cases, confirm the performance and reliability of the varistor in advance. 

   - (1) A solvent included in the resin infiltrates the varistor and impairs its characteristics. 

   - (2) Heat from chemical reaction (curing heat) generated by the resin when it cures exerts a negative effect on the varistor. 

   - (3) Expansion/shrinkage of the resin applies stress to the soldering part and causes it to crack.

<Splitting a multiple formation printed board> 

- ・ When splitting the board having components, including a mounted varistor into multiple pieces, be careful not to apply bending stress or torsional stress to the board. If bending stress or torsional stress, shown in the following diagram, is applied to the board when it is split, the varistor may develop a crack. Avoid, as much as possible, applying stress to the board. 

**==> picture [161 x 7] intentionally omitted <==**

- ・ Avoid manually splitting the board so as to keep mechanical stress to the board as small as possible. When splitting the board, use a splitting jig or a board splitter. 

- ・ Example of a board splitting jig 

An example of a board splitting jig is shown in the following diagram. Holding the part of the board that is far from the jig and applying a load bend the board excessively. Holding the part of the board that is closer to the jig and applying a load allow you to split the board with less bending.

■ Avoid a high-temperature/high-humidity storage place and keep the varistor in a storage place where temperature ranges from 5 ℃ to 40 ℃ and relative humidity ranges from 20% to 70%. 

- Do not store the varistor in a place where moisture, dust, or corrosive gas (hydrogen chloride, hydrogen sulfide, sulfur dioxide, ammonia, etc.) is present. It may impair the solderability of the terminal electrode. Also, in places where the varistor package is exposed to heat, direct sunlight, etc., packaging tape may deform or stick to the varistor which causes a problem when the varistor is mounted. Be careful in such cases. 

- A varistor storage period shall be 12 months or less. When using a varistor kept in storage for more than 12 months, confirm its solderability before using it.
