0ZRP0090FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRP0090FF1E is a resettable PPTC fuse from the 0ZRP series, designed for overcurrent protection in electronic circuits. It features a holding current of 900 mA and a trip current of 1.8 A, operating within a maximum voltage of 60 VDC. The device has a maximum rated current of 40 A and an initial resistance of 520 mOhms. It functions reliably across a temperature range of -40°C to +85°C. The component is supplied in bulk packaging with dimensions of 13.97 mm in length and 3.56 mm in height.

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
• Ensures low power consumption through minimal resistance during normal operation

Ptc Resettable Fuses Applications

• Portable electronics battery pack protection
• Peripheral interface circuit safeguarding
• Communication equipment overcurrent defense

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix FF1E corresponds to the required bulk packaging format, as other suffixes may indicate tape and reel configurations. Confirm that the 60 VDC rating aligns with the target circuit's maximum operating voltage to ensure adequate safety margins. Ensure the 900 mA holding current meets the continuous load requirements without nuisance tripping under normal thermal conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a compact, lead-free solution is required for low-voltage DC applications. The 0ZRP series offers a balance of fast response and high rupture capacity suitable for sensitive downstream components. Consider the physical footprint constraints, as the radial leaded design requires specific board space compared to surface mount alternatives.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRP family of resettable fuses, which are polymer positive temperature coefficient devices. These components serve as reusable alternatives to traditional one-time fuses, providing cost-effective protection in consumer and industrial electronics where maintenance access is limited or difficult.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 900 mA PPTC fuses from the same manufacturer series, such as the 0ZRR0090FF1E, provided the package style matches the design requirements. Cross-manufacturer replacements must match the 60 VDC rating and 900 mA holding current specifications precisely.
