Varistors(SMD)

Countermeasure for Surge Voltage and Static Electricity

AVR Series AVR-M, AVRL Types

Varistors are voltage dependent nonlinear resistive elements with

a resistance that decreases rapidly when the voltage is over the

constant value.

Varistor is equivalent with Zener diode of two series connection.

Therefore, do not have polarity.

• All specifications are subject to change without notice.

FEATURES

• No polarity, due to symmetrical current-voltage characteristics.

Equivalent to anode common type Zener diode.

• Excellent electrostatic absorption capability.

Response is as good or better than Zener diode.

Keeps symmetrical current-voltage characteristics even after

electrostatic absorption.

• Adopted the inner electrodes lamination structure.

Wide range of varistor voltages are available in series (6.8 to

39V).

Low capacitance items are available in series (1.1pF to).

World’s smallest 0603-, 1005-, 1608-, 2012-chip types and

1410-array type are available in series.

• Excellent mount reliability. Good for Pb-free soldering.

Adopted (Ni/Sn) electroplating.

Achieved good solderability and solder heat resistance.

• Can replace a Zener diode + capacitor combination.

Reduced footprint and total mounting cost.

APPLICATIONS

• Electrostatic absorption

• Pulse noise absorption
