• Features radial leads for through-hole PCB mounting

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in battery-powered equipment
• Signal line protection in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific voltage rating and package configuration against the official datasheet before integration. Confirm that the radial lead style matches the target PCB footprint requirements. Ensure the hold and trip current specifications align with the circuit's operational limits to prevent nuisance tripping or inadequate protection during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded form factor is required for low-voltage applications up to 90 VDC. The 400 mA hold current makes it suitable for protecting sensitive low-power circuits. Consider the slow blow characteristic if the application experiences brief current spikes during startup or operation without requiring immediate disconnection.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRC series of resettable fuses manufactured by Bel Fuse. The series utilizes PPTC technology to provide reusable overcurrent protection. The radial lead construction distinguishes it from surface mount alternatives within the broader product portfolio, targeting through-hole assembly processes.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 0ZRC series parts having identical 400 mA hold current and 90 VDC voltage ratings. Verify physical dimensions and lead spacing compatibility before substituting with alternative manufacturers' radial PPTC fuses.
