General Description简要概述简要概述简要概述简要概述 Polymer resettable fuse are made of polymeric PTC materials which is a matrix of 自恢复保险丝是聚合物高分子材料通过特殊工艺而成 polymer containing dispersed conductive particles Generally the device has a very 高分子粒子按一定的规律排列 正常情况下 自恢复保险丝器件处于低内阻状态 low resistance If an over current happened as a response to the damage current 当电路中电流突然增大时 the resistance will immediately increase to very high reducing the current of the 器件将会在短时间内阻值升到高阻状态 高分子膨胀 circuit to a safe value that the loading can carry Once fault to the circuit is weed out 从而起到减少过电流 and power is recuperated the polymer will deflate itself the device will reset and is 一旦故障排除后 高分子将会恢复正常规则排序 POLYMER RESETTABLE FUSE 自恢复保险丝自恢复保险丝自恢复保险丝自恢复保险丝 Model No 30V Series PUBLICATION RELEASE DATE MAY 2011REVISIONB1 ready for normal
