0ZRR0075FF2E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRR0075FF2E is a PPTC resettable fuse from the 0ZRR series, designed for overcurrent protection in electronic circuits. 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 a maximum rated current of 40 A and an initial resistance of 600 Ohms. Operating within a temperature range of -40°C to +85°C, it utilizes a radial leaded package measuring 10.4 mm in diameter and 3.1 mm in height. Packaged on a reel, this slow-blow fuse provides reliable circuit protection.

Ptc Resettable Fuses Feature Summary

• Polymer positive temperature coefficient (PPTC) technology enables automatic recovery after fault clearance without manual replacement.
• Radial leaded construction facilitates through-hole mounting on printed circuit boards for robust mechanical attachment.
• Slow-blow characteristic allows tolerance for temporary inrush currents while maintaining protection against sustained overloads.

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronics and battery-powered devices
• Circuit safeguarding in telecommunications equipment and network infrastructure
• Protection for general industrial control systems and consumer appliances

Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 0ZRR0075FF2E with official Bel Fuse documentation. Confirm that the received items match the specified 750 mA hold current and 60 VDC rating. Ensure packaging integrity is maintained, as the component is supplied in reel format. Check for compliance certifications such as RoHS where applicable. Validate supplier authorization status before acquisition to guarantee product reliability and traceability.

Ptc Resettable Fuses Selection Notes

Select this component when a through-hole solution is required for circuits operating up to 60 VDC. The 750 mA hold current suits applications needing moderate current protection with high fault current handling capability of 40 A. Consider the 600 Ohm resistance impact on low-voltage signal lines. The radial package dimensions must fit the available board space. Evaluate thermal derating requirements if ambient temperatures approach the upper limit of 85°C during normal operation.

Ptc Resettable Fuses Part Context

This device belongs to the Bel Fuse 0ZRR series of resettable fuses, which are polymer-based protective components. The series offers various hold current options and voltage ratings to suit different circuit protection needs. These fuses are commonly used in industries requiring reliable, reusable overcurrent protection solutions. The specific model 0ZRR0075FF2E represents a standard configuration within this lineup, balancing performance and cost-effectiveness for general-purpose applications.

Ptc Resettable Fuses Replacement Considerations

The bulk packaged variant 0ZRR0075FF1E serves as a direct substitute with identical electrical specifications but differs in packaging format. Verify that the target application supports through-hole mounting for both variants. Ensure that any alternative replacement maintains the same 750 mA hold current and 60 VDC maximum voltage rating to preserve circuit protection integrity.
