IEEE C62。42（TM）指南系列涵盖用于电力和电信浪涌保护装置（SPD）和设备端口的浪涌保护组件（SPC）。本部分包括正温度系数（PTC）热敏电阻元件。这些SPC通过自加热操作，并在测试结束后自动复位 无需手动干预的过电流状态。本指南涵盖了两种类型的车身 材料:聚合物和陶瓷。这些组件被称为: a） 聚合物正温度系数（PPTC）热敏电阻 b） 陶瓷正温度系数（CPTC）热敏电阻 这是指南吗？s的主题包括: -概述 -建筑 -手术 -制作 -评级 -特征 -应用实例

The IEEE C62.42(TM) guide series covers surge protective components (SPCs) used in power and telecom surge protective devices (SPDs) and equipment ports. This part covers positive temperature coefficient (PTC) thermistor components These SPCs are operated by self-heating and are automatically reset after the end of the overcurrent condition without the need for manual intervention. This guide covers the two types of body material: polymer and ceramic. These components are referred to as follows: a) Polymer positive temperature coefficient (PPTC) thermistors b) Ceramic positive temperature coefficient (CPTC) thermistors This guide's topics include the following: - Overview - Construction - Operation - Production - Ratings - Characteristics - Application examples
