53D221K

53D Series Description The 53D series radial leaded varistors provides an ideal circuit protection solution for lower DC voltage applications by offering higher surge ratings than ever before available in such small discs. The maximum peak surge current rating can reach up to 70KA (8/20 μs pulse) to protect against high peak surges, including indirect lightning strike interference, system switching transients and abnormal fast transients from the power source. Radial Lead Metal Oxide Varistor Features u Wide operating voltage (V1mA) range from 200V to1800V u Fast responding to transient over-voltage u Large absorbing transient energy capability u Low clamping ratio and no following-on current Applications u Transistor, diode, IC, thyristor or triac semiconductor protection u Surge protection in consumer electronics u Surge protection in industrial electronics u Surge protection in electronic home appliances, gas and petroleum appliances u Relay and electromagnetic valve surge absor...
