摘要
介绍了压敏电阻器和ＰＴＣＲ热敏电阻器的非热耦合组合应用，热耦合组合应用。对压敏热敏热耦合三端组件样品进行了测试，测试结果表明，压敏芯片对ＰＴＣＲ芯片的动作特性有影响，压敏芯片体积越大影响越大。采用较小尺寸的压敏电阻器与ＰＴＣＲ热敏电阻器组合，再与尺寸较大、压敏电压较高、吸收脉冲冲击能力较好的压敏电阻器一起应用效果好，安全性更有保障。
Application of the combination of varistors and PTCR thermistors, non thermal coupling or thermal coupling, is represented The result of the test of three terminal thermal coupling sample shows that the varistor chip has a effect on the performance characteristics of the thermistor chip;the larger the varistor chip volume, the stronger the effect Let a combination of small size varistors and PTCR thermistors work with varistors of large size, high voltage and high pulse shock absorption, better performances and safety will be achieved
