Description:
The 25D 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 20KA (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:
