TS250-130F-RB电路保护的PTC可复位保险丝规格书PDF中文资料

TS250-130F-RB属于电路保护的PTC可复位保险丝。由力特公司制造生产的TS250-130F-RBPTC 可复位保险丝PTC 可复位保险丝可在电流超过一定限值时用于阻断电流（过流保护）。保险丝的工作原理是：其温度会因电流增大而升高，导致电阻变大。跳闸电流为 14 mA 至 50 A，跳闸时间为 8 ms 至 90 s。PTC = 正温度系数。

This family of telecommunication and networking

devices was initially designed to meet the growing

demand for resettable overcurrent protection. These

product families help provide protection against

damage caused by power cross and power induction

surges as defined in ITU, Telcordia GR1089, and

UL60950. Available in chip, surface-mount, and radialleaded configurations, TE’s PolySwitch devices help

improve the reliability of customer premise and network

equipment world wide.
