Description

Features: Halogen free, SMD Electronic devices, High structural intensity, Over current protection, Over charge protection, Over heating protection, Compatible with reflow soldering processes.

SCF Introduction: 
  • Self Control Fuse (SCF)is a three-terminal protective element,mainly used secondary protection  in notebook computers lithium ion battery , tablet computers lithium ion battery and mobile phones lithium ion battery.
  • SCF protects lithium ion battery from the overcharge and the overcurrent . When the lithium battery overcurrent, the fuse will melt and cut off the current or when the heater is activated and melts fuse element to stop overcharging, the flow electric current through the heater stops as soon as the charging circuit is cut off.
  • SCF can be installed by the SMT machine and reflow soldering.
