Application:
Mainly used in various current detection resistors, such as small household appliance control boards, mobile power supplies and mobile devices, industrial control, automotive electronics, the Internet of things, mobile phones, etc. they are widely used. The main reason is that the product requirements are constantly improving, requiring low power consumption and high performance. Therefore, the application of milliohm resistors will be more and more widely.
