详细说明

  力特littelfuse2920L185 1.85A 33V 自恢复保险丝 

  自恢复保险丝是由经过特殊处理的聚合树脂(Polymer)及分布在里面的导电粒子(Carbon Black)组成。在正常操作下聚合树脂紧密地将导电粒子束缚在结晶状的结构外,构成链状导电电通路,此时的可恢复保险丝为低阻状态(a),线路上流经自恢复保险丝的电流所产生的热能小,不会改变晶体结构。当线路发生短路或过载时,流经自恢复保险丝的大电流产生的热量使聚合树脂融化,体积迅速增长,形成高阻状态(b),工作电流迅速减小,从而对电路进行限制和保护。当故障排除后,PTC可恢复保险丝重新冷却结晶,体积收缩,导电粒子重新形成导电通路,自恢复保险丝恢复为低阻状态,从而完成对电路的保护,无须人工更换。
