The 34S varistor large current 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. Used in electronic circuits for overvoltage protection, voltage range: 46～1800V, can withstand 20～40kA surge energy.
