0ZRP0075FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRP0075FF1E is a polymeric PTC resettable fuse designed for overcurrent protection. It features a hold current of 750 mA and a trip current of 1.5 A, with a maximum voltage rating of 60 VDC. The device has an initial resistance minimum of 30 mOhms and a maximum interrupting current of 40 A. It utilizes radial leads with a spacing of 5.10 mm (0.201 inches) and operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault clearance without manual replacement
• Offers dual-mode protection against both overcurrent and excessive temperature conditions
• Features a low-profile radial disc package suitable for through-hole PCB mounting

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact circuit protection
• Battery packs and power supply input lines
• Communication equipment interface circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific lead configuration and pitch dimensions against the target PCB footprint before integration. Confirm that the thermal environment does not exceed the specified operating temperature limits to ensure reliable trip characteristics. Check for updated RoHS compliance status in the latest manufacturer documentation prior to final procurement approval.

Ptc Resettable Fuses Selection Notes

Select this component when a radial form factor is required for 750 mA applications. Ensure the system's normal operating current remains below the 750 mA hold current threshold. Verify that the maximum circuit voltage does not exceed 60 VDC. Consider the 30 mOhms initial resistance impact on overall circuit efficiency during design validation.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRP series of polymeric PTC resettable fuses from Bel Fuse Inc. The series is characterized by its radial leaded construction, making it distinct from surface-mount alternatives like the 0ZCG or 0ZCF series. It serves as a reusable alternative to traditional one-time fusible links in low-voltage DC applications.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include the 0ZRR0075FF1E and 0ZRE0075FF1A, which share similar electrical ratings but differ in physical packaging and voltage specifications. Cross-reference datasheets to confirm mechanical fit and voltage derating requirements.
