Self Control Fuse WSFB Series
Description
WSFB Series is a three terminals surface mountable battery protector that can protect against both overcurrent and over-charging. It comprises a fuse element to ensure stable operation under normal electrical current and to cut off the current when overcurrent occurs. It also comprises a resistive heating element that could be used in combination with a voltage detecting means, such as IC and FET. When overvoltage is detected, it will generate heat to blow the fuse to achieve overvoltage protection.
Features
- Halogen Free
- Protection for both overcurrent and overcharging
- Surface Mount
- Fast response
