High Precision PPTC Resettable Fuses Overcurrent Protection Fast Response for Li-ion Battery


HCET PPTC resettable fuses utilize polymer positive temperature coefficient technology and are designed for consumer electronics, lithium battery packs, and USB interface devices. When an overcurrent or short-circuit occurs in a circuit, its resistance jumps instantly to cut off the current, and it automatically restores conduction after the fault is removed without manual intervention. Supporting a wide current range of 5A-30A, it provides a reliable overcurrent protection solution that extends equipment life and reduces maintenance costs.

Product feature:

  • Fast response: millisecond overcurrent blocking to prevent equipment damage.
  • Self-recovering function: no need to replace, saving maintenance time and cost.
  • Wide voltage coverage: 6V to 60V rated voltage, adaptable to a wide range of electronic devices.
  • High stability: -40°C to 85°C wide temperature operation, stable performance in harsh environments.
