力特250 贴片NANO2保险丝,0443005.DR

Littelfuse 443 系列 - NANO2®延时超小型表面贴装保险丝

型号：0443005.DR

电流：5A

电压：250V

250 NANO2保险丝应用：交流/直流电源适配器、电信设备系统电源、便携系统内置式交流/直流转换器、照明系统

敞开式熔断器结构简单,熔体完全暴露于空气中,由瓷柱作支撑，没有支座，适于低压户外使用。

分断电流时在大气中产生较大的声光。

半封闭式熔断器的熔体装在瓷架上，插入两端带有金属插座的瓷盒中,适于低压户内使用。

分断电流时,所产生的声光被瓷盒挡住。贴片保险丝在小型保险丝行业中是技术含量相对较高的

新品种。

The chip fuse is a new technology with relatively high technology content in the small fuse

 industry. Surface Mount Fuses

Can be divided into patch current fuse and patch self recovery fuse.

SMD fuse can be divided into disposable patch fuse and patch self recovery fuse, one time 

fuse protection.

After the protection, it needs to be replaced. After the recovery fuse is protected, the power 

failure can be recovered by itself and can be reused.
