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

型号：0443001.DR

电流：1A

电压：250V

250 NANO2保险丝是一款小型四方表面贴装保险丝，用于为支持更电压且对空间要求极为敏感的设备。

保险丝(fuse)也被称为电流保险丝，IEC127标准将它定义为"熔断体（fuse-link)"。其主要是起过载保护

作用。 电路中正确安置保险丝，就会在电流异常升高到一定的高度和热度的时候，自身熔断切断电流，

保护了电路安全运行。

熔断器（fuse）是指当电流超过规定值时，以本身产生的热量使熔体熔断，断开电路的一种电器。

Fuse is also known as current fuse, and IEC127 standard defines it as "fuse-link". It mainly plays the 

role of overload protection. When the fuse is properly placed in the circuit, the fuse will cut off the 

current when the current is raised to a certain height and heat, and the safety of the circuit will be 

protected. More than 100 years ago, the fuse invented by Edison was used to protect the expensive 

incandescent lamps. With the development of the times, the fuse protected the power equipment 

from the damage caused by the overheating of the electric current, and avoided the serious damage 

caused by the internal failure of the electronic equipment.
