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

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

(Rectangular chip fuse) 

## **Use environments and cleaning conditions** 

- This product (Fuses) is not designed for use in specific environments. Using the fuses in the following specific environments or service conditions may affect the performance/reliability.  Avoid using it in such specific environments. If you intend to use the fuses in such environments, checking the performance, reliability, etc., of the product sufficiently is your own responsibility. 

   - (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 static electricity and electromagnetic waves are strong. 

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

   - (6) Sealed or coated with a resin. 

   - (7) Solder flux of the resistor soldered with no-clean type solder, etc., is cleansed with a solvent, water, or a water-soluble cleaner, etc. (Water-soluble flux residues have a particularly large influence on a resistor.) 

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

   - (9) Used in a contaminated state. 

(Example: Touching the resistor mounted on a printed board leaving sebum on the fuses (improper handling)) 

- Sealing the fuses with a resin in a resin potting process, damp-proofing process, etc., applies excessive stress to the fuses, which may cause the internal electrodes a connection problem. In such cases, the proper operation of the fuses is not guaranteed. If you intend to use the resistor in such environments, checking the performance, reliability, etc., of the product sufficiently is your own responsibility. 

- Do not leave the fuses immersed in a solvent for a long time. When using the fuses immersed in a solvent, confirm the operation of the product mounted on the board. 

- When a cleaning solution or cleaning condition for cleaning the printed board or a drying condition for drying the printed board after soldering the fuses is improper, it may have a negative effect on the performance/reliability of the fuses. Confirming these conditions sufficiently is your own responsibility. Also examine the effects of soiled cleaning agent, cleaning residues, and post-cleaning contaminations, and control for these effects properly. 

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

- When the fuses is heating abnormally or emitting a smell, stop using the fuses immediately, for example, turn off the main power supply of the device. Also, keep your face and hands away from the product as it may become hot and cause burns. 

- The fuses is so thin that it may break easily when subjected to impact. Before putting the fuses in use, confirm that the fuses has not been broken by impact that applied thereto when mounted on the printed board. Applying impact to the fuses or pinching the fuses with a hard tool (pliers, tweezers, etc.) may the fuses or its protective film, which affects its performance. Be careful to avoid such cases. 

- Do not reuse a fuses having been used on a printed board and removed therefrom. Do not touch the fuses with your bare hands. 

- Be careful not to drop the fuses on the floor, etc. The fuses is likely to suffer mechanical or electrical damage when dropped on the floor. Avoid using said fuses. 

- The fuses may have its resistance value changed due to electrostatic discharge (ESD). Take ESD prevention measures when handling the fuses. ESD prevention measures include an environment where static electricity is not likely to be generated (recommended RH: 40% to 60%), by wearing an earth band, conductive gloves, etc., grounding the device in which the fuses is incorporated, and placing a conductive mat, etc., on a work platform. 

- Select a rated current for the chip fuse so that a current flowing through the chip fuse, in a normal condition, is 70% or less of the rated current. Do not let a current larger than the rated current flow continuously through the chip fuse. 

15-Mar-24 

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

- Be careful when a pulse current larger than the rated current, such as an inrush current or surge current at the moment of turning on the power supply, briefly flows through the chip fuse. It may cause the chip fuse to fuse off, which is undesirable. Calculate the I2-t value of the pulse current, and from the I2t-t characteristics curve, determine the tolerance of the chip fuse to the number of pulses applied. Based on these I2-t value and tolerance, make a decision on whether or not to use the chip fuse. Determining the tolerance involves technicalities. Consult our sales staff in advance. 

- The product fuses off when carrying a current two times or more of the rated current. Select a product so that the abnormal current generated in the event of a circuit failure of your product is at least twice the rated current of the product. Make sure that the abnormal current does not exceed the maximum cutoff current of the product. 

- The chip fuse is intended for use on the secondary side of the power supply. Do not use the fuse on the primary side of the power supply. Keep source voltage applied to the chip fuse equal to or lower than the rated voltage of the chip fuse. 

- The load characteristics and fuse characteristics of the chip fuse are affected by the ambient temperature. Before actually using the chip fuse, evaluate and confirm the operation of the chip fuse incorporated in your product while sufficiently taking into consideration the category temperature range. 

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

- To prevent a case where a transient load (e.g., a pulse for a short period) too large for the product to handle is applied, make sure to evaluate and confirm the operation of the product incorporated in your product. Applying power or voltage (current) larger than the rated power or rated voltage (current) to the fuses may impair its performance and reliability. Make sure to use the fuses with power or voltage (current) equal to or lower than the rated power or rated voltage (current). The product warranty does not cover usage where an excessively large load, such as a pulse current, is applied to the product. 

- The fuses may have a high temperature even when used with power equal to or lower than the rated power. Be careful in such cases. Another factor to be considered are effects on the board, peripheral components, etc., and the effects of peripheral components on the fuses. Make sure to confirm first that the temperature of the fuse elements incorporated in your product is equal to or lower than the specified temperature, and then use the fuses. 

- Continuously using the chip fuse in a fused state is not allowed. 

When the chip fuse fuses off, immediately turn off the power supply to cut off the current flow. 

- When a fuses is used in a high-frequency circuit, the fuses may fail to offer the required characteristics. Check whether the fuses offers the required characteristics in the actual circuit in which the fuses are incorporated. 

- Be careful that unusual stress caused by an excessive bend of the printed board is not applied to the fuses. Design the circuit structure such that the fuses is not close to a perforated line for board splitting or on a line with sizable holes bored on the board. 

- When a different component is mounted on the board where the fuses has been soldered, be careful that the board does not bend excessively. If necessary, provide the board with backup pins (support pins) to keep it straight. 

- Avoid manual board splitting. Use a jig, etc., to break the board so that it does not bend excessively when split apart. 

## **Mounting conditions** 

- When the product is used under mounting conditions departing from mounting conditions specified in our specification sheet, the product may be exposed to unexpected stress to fail. Be careful to avoid such a case. When mounting the fuses on a printed board, set the fuses's front and back surfaces in the direction indicated by the tape. Make sure to evaluate and confirm the operation of the fuses incorporated in your product and determine whether the fuses is usable as a component of the product. 

- Set soldering conditions for the fuses within the recommended soldering conditions specified by our company. Any time, soldering condition departing from the specified soldering condition, such as a high peak temperature or a long heating may impair the performance/reliability of the fuses. Note that the specified soldering conditions indicate conditions under which degradation of the fuses characteristics does not occur but do not indicate conditions under which stable soldering can be performed. Check and set individual conditions under which stable soldering can be performed. 

- Heat the fuses in advance so that a difference between the soldering temperature and the temperature of the fuses surface is reduced to 100 ℃ or lower. When dipping the soldered fuses in a solvent, etc., to cool fuse elements rapidly, ensure that the temperature difference between the fuses and the solvent is 100 ℃ or lower during the dipping.

- When soldering the fuses using a soldering iron, apply hot air, etc., to the fuses to heat it sufficiently in advance and then solder the fuses without bringing the soldering iron tip into contact with the product. If the temperature of the soldering iron tip is high, finish the soldering work quickly (within 3 seconds when the temperature of the soldering iron tip is 350 ℃ or lower). In the case of a fuses with low resistance, the resistor may fail to offer the exactly intended resistance value because of the variation in the solder volume, etc. Make sure to confirm the resistance value of the fuses in the actual circuit configuration. 

- Soldering the fuses with too much solder or too little solder results in the poor reliability of the solder connection of the fuses. Use the proper volume of solder in the soldering process. Sufficiently check for the volume of solder used. 

- Soldering with high bond strength or special property solder may affect the quality of the fuses. Do not use such solder. 

- Use rosin-based solder flux. When using highly active solder flux made mainly of halogen (chlorine, bromine, etc.), flux residues may affect the performance and reliability of the fuses. Check the effects of flux residues before using the solder flux. Do not use highly acidic flux, water-soluble flux, or flux containing fluoride ions. When solder flux sticks to the fuses after the soldering process, the activation energy of the flux may corrode the fuses and cause it to fail. Prevent solder flux from sticking to the fuses.
