Thin Film SMD 0805 Metal Oxide Varistor MVR0805-431G 2012 275VAC SMT For Surge Voltage And Static Electricity
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 afterelectrostatic absorption.
• Adopted the inner electrodes lamination structure. Wide range of varistor voltages are available in series (6.8 to 470V).
• 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.
