正温度系数过流保护器件（PTC

[中文适用范围]： 本 SAE 推荐实践定义了 PTC（正电阻温度系数）过流保护装置的测试条件、程序和性能要求。 PTC 通常是聚合物 (PPTC) 或陶瓷 (CPTC)。请务必注意电池电压与电源网络/系统电压与最大电池电压的关系：（12 V/14 V/16 V、24 V/28 V/32 V 和 36 V/42 V/58 V）。所有电压均为直流电压。这些设备的额定最大工作电压通常为 16V（对于 12V 电池）、32V（对于 24V 电池）和 58V（对于 36V 电池/42V 电源网）。 PTC 器件在响应过流情况后以及在包含 PTC 的受影响电路中消除这种情况后被认为是自复位的。 [外文原描述]： This SAE Recommended Practice defines the test conditions, procedures, and performance requirements for PTC (positive temperature coefficient of resistance) overcurrent protection devices. PTCs are typically either polymeric (PPTC) or ceramic (CPTC). It is important to note battery voltages versus powernets/system voltage versus max battery voltages: (12 V/14 V/16 V, 24 V/28 V/32 V, and 36 V/42 V/58 V). All voltages are DC. These devices are typically rated with a maximum operating voltage, which for vehicular systems need to be 16 V (for 12 V batteries), 32 V (for 24 V batteries), and 58 V (for 36 V batteries/42 V powernets). PTC devices are considered to be self-resetting after responding to overcurrent conditions and after such condition has been removed from the affected circuit containing the PTC.Cross Reference: AEC-Q200,ANSI/J-STD-002,ISO 7637-1,ISO 7637-2,ISO7637/1,ISO7637/2,J1211_201211,J1455_201101,J1455_201703,MIL-STD-202G,MIL-STD-810D,TSB002_201411,UL1077,UL94
