0ZRS0070FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRS0070FF1E is a radial leaded PPTC resettable fuse designed for PCB mounting. It features a 700 mA hold current and a 1.4 A trip current, operating at a maximum voltage of 32 VDC. The device has a resistance of 800 mOhms and an interrupt rating of 100 A. It supports a wide temperature range from -40°C to +125°C and holds AEC-Q200 qualification. Physical dimensions include a height of 3 mm.

Ptc Resettable Fuses Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Radial leaded termination style for through-hole PCB integration
• Self-resetting polymeric positive temperature coefficient construction

Ptc Resettable Fuses Applications

• Automotive electronic circuit protection
• Overcurrent protection in low-voltage DC systems
• PCB-mounted component safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the suffix FF1E corresponds to bulk packaging rather than tape-and-reel configurations found in similar series variants like FF2D. Confirm AEC-Q200 certification status with the manufacturer prior to deployment in safety-critical automotive applications. Ensure the 32 VDC rating aligns with the target circuit's maximum operating voltage requirements.

Ptc Resettable Fuses Selection Notes

Select this component when a 700 mA hold current and 32 VDC maximum voltage are required for automotive-grade protection. The radial leaded package suits manual or wave soldering processes. Compare against higher current variants if load requirements exceed 700 mA, or consider lower voltage ratings if the application operates below 32 VDC but requires different physical footprints.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRS series of radial leaded PPTC resettable fuses. The series provides overcurrent protection for various electronic circuits. The 0ZRS designation indicates a specific voltage and current rating profile within the broader product family, distinguished by its automotive qualification and radial lead configuration.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes may include other 0ZRS series parts with matching electrical ratings. Verify that alternative components maintain the same AEC-Q200 qualification and radial lead spacing for board compatibility.
