低电压氧化锌压敏电阻器的研究

Study on ZnO Varistors with Low Breakdown Voltage

】研究了一种制造低电压氧化锌压敏电阻器的方法。在基本成分的基础上适当加入二氧化钛可降低梯度电压（Ｖ１ｍＡ／ｍｍ）。

A method for producing ZnO varistors with low breakdown voltage is discussed Doping just right amount of TiO 2 can reduce the grade voltage V 1mA /mm,doping B and thermal treating can improve leakage current I and non linear coefficent.As a result,the reliable products with fine performance have been obtained
