Surface mounted type fuse

10 Amperes/12 Amperes SFH Series Self Control Protector(SCP)

Suitable for mobile devices such as tablet PC and notebook PC.

  • Product name
    SFH-0412 / SFH-0810 / SFH-1212 / SFH-1412
  • Features
    • Protects Li-ion batteries from overcharging (overvoltage) and overcurrent.
    • When overcharging occurs, the fuse element melts to shut off the circuit, and simultaneously the power to the heater is also cut off.
    • Placing a heater directly under the fuse element breaks the circuit quickly.
