Surface mounted type fuse

5 Amperes(small and thin) SFR Series Self Control Protector(SCP)

Downsizing of 1.8 x 2.7 x 0.75 mm. Applicable to LPS devices that comply with the IEC, the International Standards for product safety.

  • Product name
    SFR-0405 / SFR-0805 / SFR-1205 / SFR-1405
  • 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.
