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。
PPTC的选用技巧:
1.确定以下的电路运行参数：
正常工作电流 - IHOLD
电路电压相当大值 - VMAX
相当大中断电流 - 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。
