AVR Ser ies 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.

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 0402-, 0603-, 1005-, 1608-, 2012-chip types 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
