  • Fast-acting response (vs HFA80A-F2W)
  • Littelfuse brand reliability (vs HFA80A-F2Z)

Design Notes

Fuses generate heat during normal operation. Ensure adequate airflow and PCB copper area to dissipate heat. Derate the fuse's current rating at elevated ambient temperatures to prevent nuisance trips. Refer to the datasheet for derating curves.

Place the fuse close to the power input to minimize trace inductance. Use wide, short traces to reduce voltage drop and heat generation. Ensure proper clearance and creepage distances for high-voltage applications.

Do not exceed the fuse's rated voltage or breaking capacity. Ensure the continuous operating current is below 80A to avoid nuisance trips. Consider inrush currents that may cause the fuse to blow prematurely; select a fuse with appropriate I2t rating.
