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
