PTC自复保险丝为豆浆机等小家电的电机提供堵转保护
在以豆浆机、搅拌机、打蛋机等为代表的家电中,为避免遭遇“难啃”的大块头引起电机堵转从而烧毁电机等,可使用PTC作为电机的堵转保护,一旦电机发生了堵转,由于堵转的电流是数倍于正常工作电流,PTC只要流过的电流是正常工作电流的2倍即可启动保护,而此刻电机的整体温度往往并没有升起来,避免了高温对电机的冲击。

【经验】自恢复保险丝和TVS的结合使用,可防止四种情况造成的损坏
单独使用自恢复保险丝,或者与TVS二极管结合起来使用,都能防止负载电流过大、转换器出现故障、发动机激活时产生的瞬变电压以及汽车电池极性接反导致器件损坏。在选择PPTC自恢复保险丝器件时,必须考虑到最大负载电流、最高环境温度以及进入高阻抗状态所需要的时间。
【选型】国产自恢复保险丝SCF016-1206RB用于灯光控制器电源输入过流防护设计,低待机功耗0.0256W
为避免智能灯光控制器因负载短路造成损伤,一般需要在控制器与电池间加上一颗PPTC自恢复保险丝做过流保护设计,推荐硕凯电子自恢复保险丝SCF016-1206RB,1206表贴封装,最大额定工作电压30Vdc,在环境温度25℃条件下,保持电流0.16A。
【应用】国产自恢复保险丝用于智能流量调节阀控制板电源输入过流防护,1206表贴封装助力小型化设计
为避免智能流量调节阀电源输入因负载短路异常出现烧毁风险,一般选用自恢复保险丝做过流保护设计,推荐国产硕凯电子的自恢复保险丝SCF050-16-1206RB,采用1206表面贴装设计,最大工作电压为6VDC,兼容性更强。
【经验】PTC自恢复保险丝工作原理及选型细节解析
使用传统保险丝或是使用最新研发的自恢复PTC都可以实现过流电路保护。两者都是通过对电路中过量电流产生的发热现象做出反应从而实现保护功能。硕凯电子将在本文介绍PTC自恢复保险丝工作原理及选型细节。
