Surface mounted type fuse

30 Amperes(Small) SFS Series Self Control Protector(SCP)

Achieving ultra-low resistance, a low height. Suitable for devices that support fast charging.

  • Product name
    SFS-0430A / SFS-0830A / SFS-1230A / SFS-1430A
  • Features
    • Achieving rated current 30 Amperes and Pb-free as a surface mounted fuse.
    • 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.
    • Achieving low resistance (0.55mΩ) and a low height (0.9mm).
