The 7D varistor plug-in series produced by Ruilongyuan Electronics is a semiconductor voltage-limiting surge device made of zinc monoxide as a raw material at high temperature. It is widely used for its excellent nonlinear characteristics and strong surge absorption capacity. Overvoltage protection in electronic circuits, voltage range: 18 ~ 820V, can withstand surge energy of 0.25 ~ 1.75kA.
