  • Product name
    SFJ-0415T / SFJ-0815T / SFJ-1215T / SFJ-1415T / SFJ-2015T / SFJ-2815T / SFJ-3215T / SFJ-4015T / SFJ-4815T / SFJ-5615T
  • Features
    • Achieving a low height of 0.85 mm. Suitable for compact and slimline mobile devices.
    • 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.
    • This is a Pb-free* product.
      * The European RoHS Directive, which restricts the use of hazardous substances, defines Pb-free as a Pb content of 1,000 ppm or less.
