SMD MOV 3225 series plastic-encapsulated varistors

Introduction

Plastic-Encapsulated SMD Metal Oxide Varistors (SMD MOVs) are surface-mount surge protection devices featuring a metal oxide varistor chip encapsulated in a plastic molded structure. Combining high surge absorption capacity, compact packaging, and automated assembly advantages, they are ideal for transient overvoltage and surge protection in circuits such as power inputs, LED lighting, industrial controls, communication equipment, new energy devices, and automotive electronics.

Currently, this series primarily covers 3225 and 4032 package sizes. They can be selected based on different operating voltages, surge currents, and application scenarios, making them perfect for small-to-medium power supplies and electronic equipment with strict requirements for space, reliability, and assembly efficiency.
