摘　　要：介绍多层片式ZnO压敏电阻器的材料组成、电极材料、生产工艺及电性能,并与圆片引线型压敏电阻器进行了比较。多层片式ZnO压敏电阻器具有许多优点,如体积小、通流容量大,响应速度快,表面安装性好和实现低压化等,流延和电镀是多层片式压敏电阻器生产中比较重要的工艺。最后指出多层片式压敏电阻器的方向。The chemical composition, electrode materials, manufacturing technology and electrical performance of ZnO multilayer chip varistors and recent research achievements of ZnO based varistor materials are introduced, the application of multilayer chip varistors is also pointed out. Compared with disc varistors, the multilayer chip varistors have more superior electrical performance. The main technology characteristics of multilayer chip varistor are tape casting and plating, which are different from disc varistors. Finally, the development of application and the future trends of multilayer chip varistors are suggested.
