07DSeries

Description

The 07D series radial leaded varistors provide an ideal circuit protection solution for

lower DC voltage applications by offering higher surge ratings than ever. The maximum

peak surge current rating can reach up to 1.75KA (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.
