Radial Lead Metal Oxide Varistor (MOV) 20D Series Description The 20D 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 10KA (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. Features Applications  Wide operating voltage (V1mA) range from 18V to 1800V  Fast responding to transient over-voltage  Large absorbing transient energy capability  Surge protection in consumer electronics  Low clamping ratio and no following-on current  Surge protection in industrial electronics  Meets MSL level 1, per J-STD-020  Surge protection in electronic home appliances, gas and  Transistor, diode, IC, thyristor or triac semiconductor protection petroleum appliances  Relay and electromagnetic valve surge absorption General Characteristics Material No Radioactive Material Operating Temperature -40℃ ~ +85℃ Storage Temperature -55℃ ~ +125℃ Body Nickel Plated Leads Tin Plated Devices with No lead Nickel Plated SOCAY Electronics Corp., Ltd.
