## **CHARACTERISTICS OF CHIP VARISTOR** 

Varistors are voltage dependent nonlinear resistive elements with a resistance that decreases rapidly when the voltage is over the constant value. 

Varistors become zener diode of 2 serial connection and equivalent, and does not have polarity.

## **Attention on a circuit board design** 

## **Board design** 

When attached to chip varistors, amount of silver used (fillet size) has direct impact on chip varistors after mounting. Thus, sufficient consideration is necessary. 

## **Set of land dimensions** 

(1) As the stress rises in the chip varistors owing to the increase in silver, breakage and cracks will occur. Cause including crack, as caution on board land design, configure the shape and dimensions so that the amount of silver is appropriate. If you installed 2 or more parts in the Common Land, separated by a solder resist and special land of each component.

(2) When peak levels panning-at soldering is excessive, by solder contraction stress, mechanical-thermal stress causes a Yasuku chip crack. In addition, when the peak level is underestimated, terminal electrode fixed strength is insufficient. This causes  chip dropouts and may affect circuit reliability. Representative example of the panning of peak levels is shown in the following.

## **Soldering** 

Significant impact is possible on the performance of chip varistors, flux checks something about follow, please use. 

Direct iron tip is in contact with the (2) chip varistors body, and the strain owing to thermal shock in particular grows even if a crack is generated. Therefore, please do not touch it directly to the terminal electrodes. 

(1) Flux uses one with 0.1wt % (Cl conversion) or less halide substance contains amounts, please. In addition, do not do this with strongly acidic objects. 

Flux during is soldered (2) Chip varistors is applied the smalleset amount necessary, please. 

- (3) If Used soluble flux, perform thorough wash particularly, please.

## **Chip varistors** 

**RoHS Directive Compliant Product Compatible with lead-free solders** 

## **Attention after implementation** 

## **Cleaning** 

(1) If cleaning liquid is inappropriate, residues and other foreign body of fluxes builds up on chip varistors, and can degrade the performance of chip varistors (particularly the insulation resistance). (2) Wash conditions may compromise performance of chip varistors if they are improper (wash due, wash excess). 

(2) During each substrate operational check, push pressure with contact failure of check pin of boards checkers of check pin may be toned up to be prevented. As substrate is bent under loading, chip varistors is broken owing to stress. There is also the possibility that solder on the terminal electrode will peel off. Follow the diagram for reference, and check that the substrate bends, please. 

## **2-1) For wash due** 

- (a) By substance of a system in flux residue halide, metal including terminal electrodes may experience corrosion. 

- (b) Substance of a system in flux residue halide builds up on chip varistors, and reduces the insulation resistance. 

- (c) Soluble flux makes comparisons of colophony series flux, and there is event with trends of significant (1) and(2). 

## **2-2) For excess wash** 

- (1) Owing to lavage, chip varistors deteriorates, and reduces performance of chip varistors. 

- (2) In ultrasonography, when output is passed, substrate resonates size, and crack occurs in body and sprang of chip varistors in vibration of substrate. Since this may reduce the strength of the terminal electrode, please note the following conditions. [Please review the italicized portion, as I am unsure what you mean to convey here.] 

   - Ultrasound output Ultrasonic frequency Ultrasound cleaning time 

2-3) Concentration including halogen that when cleaning liquid to pollution, when you released is higher, and may cause similar of results into wash due.

## **SAFETY REMINDERS** 

Please pay sufficient attention to the warnings for safe designing when using this products. 

## **REMINDERS** 

O Please pay careful attention to the precautions and follow safe designing practices when using these products. 

- O Please observe the following precautions in order to avoid problems with chip varistors such as characteristic degradation and element destruction 

Please store these products in an environment with a temperature of 5 to 40°C and humidity level of 20 to 70%RH, and use them within six months. 

Poor storage conditions may lead to the deterioration of the solderability of the edge electrodes, so please be careful to avoid contact with humidity, dew condensation, dust, toxic gas (hydrogen, hydrogen sulfide, sulfurous acid, chlorine, ammonia, etc.), direct sunlight, and so on. 

Please do not use products that have been dropped or detached when mounting. 

Please solder with the reflow soldering method, and not the flow (dip) soldering method. 

- O Please observe the following precautions to avoid problems with varistors such as characteristic degradation and element destruction, which ultimately lead to the generation of heat and smoke with the elements.
