Zinc Oxide Varistor MOV Block MYL34S-621P3 385VAC 505VDC 620V For Surge Protection
Varistors are used to protect a circuit from high voltage surges. When a high voltage surge is applied to a circuit, the outcome is usually catastrophic to the circuit. A capacitor may be installed across the signal lines. However, this capacitor cannot suppress voltage surges.
Wide operating voltage (V1mA) range from 82V to 1600V
Fast responding to transient over-voltage
Large absorbing transient energy capability
Low clamping ratio and no follow-on current
Meets MSL level 1, per J-STD-020
Operating Temperature:-40℃ ~ +85℃
Storage Temperature:-40℃ ~ +125℃
Transistor, diode, IC, thyristor or triac semiconductor protection
Surge protection in consumer electronics
Surge protection in industrial electronics
Surge protection in electronic home appliances, gas and petroleum appliances
Relay and electromagnetic valve surge absorption
