20D221K Overview

VDR(Voltage Dependent Resistor)

Radial Lead Varistor (MOV)
20D
10D 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.
