MOV压敏电阻
|
一、MOV的简介 压敏电阻,简称MOV,分为贴片和插件两类,贴片小MOV常用于静电防护,通常设计在最靠近板边处的接口端,尤其会是在主要的电源汇入处或传输端,重点就是一开始让能量进入时就能稳压。MOV作用是预防雷击造成的大突波电压跟着线路进到产品导致产品损毁;预防电源端不稳定的瞬态电压,跟着开关端进入产品,使产品功能破坏;预防静电进入产品,使产品破坏。 二、MOV的选用技巧 1. 确认最大容许电压: (产品工作电压/电源电压),电源供应系统:交流或直流; 2.注意供电电压的稳定性:士 10%,+30%或+20%; 3.最大抑制电压(设备可接受的暂态突波电压); 4.焦耳值Energy=K*Vc(V)*lpp(A)*Time(S) 5. V1mA=1.5Vp=2.2Vac, 式中,Vp为电路额定电压的峰值(1.414*Vac), Vac为额定交流电压的有效值Vdr压敏电阻的电压值选择至关重要,它关系到保护效果与使用寿命。 |
