华巨电子是专业的热敏电阻生产商,公司主要于热敏电阻,压敏电阻,自恢复保险丝的研发和生产。公司依托强大的研发能力最新推出小电流,超稳定的陶瓷贴片自恢复保险丝,为公司又一主打产品。
华巨电子研发的SMD小型过流保护型PTC热敏电阻主要用于短路测试对策措施、限流电阻等的过流过热保护,直接串联在负载电路中,在线路出现异常状况时,能够自动限制过电流或阻断电流,当故障排除后又恢复原态,俗称“万次保险丝”。
应用原理:
将过流保护型型PTC热敏电阻串联在电源回路中,当电路处于正常状态时,流过PTC的电流小于额定电流,PTC处于常态,阻值很小,不会影响被保护电路的正常工作。当电路电流大大超过额定电流时,PTC陡然发热,阻值骤增至高阻态,从而限制或阻断电流,保护电路不受损坏。电流电流回复正常后,PTC亦自动回复至低阻态,电路恢复正常工作。
