Self Control Fuse WSFC Series

Description

WSFC 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
