PPTC自恢复保险丝

一、PPTC的简介 自恢复保险丝,简称PPTC.是一种正温度系数聚合物热敏电阻,作过流保护用,可代替电流保险丝。电路正常工作时它的阻值很小(压降很小),当电路出现过流使它温度升高时,阻值急剧增大几个数量级,使电路中的电流减小到安全值以下,从而使后面的电路得到保护,过流消失后自动恢复为低阻值。其效果与开关组件类似,只是响应速度较慢。 二、PPTC的选用技巧 ●正常工作电流- IHOLD ●电路电压最大值- VMAX ●最大中断电流- IMAX ●工作环境温度 2.选择合适的封装形式:贴片PTC或者插件PTC。 3.比较的VMAX和IMAX的PTC数据表中的评级,以确保电路参数不超过这些额定值。 4.验证PTC的运行环境温度为它的正常工作范围内。确定Ihold和IMAX的温度曲线。 |
