Chip Varistors Countermeasure for surge voltage and static electricity AVR series Type: AVR-M AVRL Issue date: September 2011 • All specifications are subject to change without notice. • Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. (1/10) Conformity to RoHS Directive 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.

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.
