压敏电阻器
压敏电阻器是以氧化锌为材料烧结而成的半导体限压型浪涌器件;它以其优异的非线性特性和高的浪涌吸收能力被广泛应用于电子电路中进行保护。产品主要用在交/直流电源电路及各类低频信号、控制电路板及相关的防雷模块上作浪涌保护。压敏电压可从18V至1800V;单体同流量可达70KA甚至更高,本体直径有Φ5,Φ7,Φ10,Φ14,Φ20,Φ25,Φ32,Φ40,Φ53及34*34方片等其他规格尺寸,也可为客户定制规格。产品通过一系列的国际安规认证:UL、VDE、CSA及相关的无铅认证,符合MOV在SPD上浪涌测试标准和IEC61643-331-2003标准。
Metal Oxide Varistors (MOV’s) use zinc oxide that has been heat treated and formed into a disc. The zinc oxide disc acts as a non-linear resistor, clamping the voltage at a given level. Most applications for MOV’s are in power transmission lines and circuits that are controlled by low frequency signals. BrightKing provide a full range of MOV’s, with break-down voltages from 18V to 1800V and surge currents of up to 70KA or more. The company offers round varistors with diameter sizes (measured in millimetrer) of: Φ5, Φ7, Φ10, Φ14, Φ20, Φ25, Φ32, Φ40 & Φ53. A square model with 34mm sides is available and custom-made sizes are also possible. BrightKing MOV products are RoHS WEEE compliant and meet the following standards and certifications: UL; VDE; CSA. BrightKing MOV products may be incorporated into SPD’s that are certified to standard ICE 61643-331-2003.
