0ZRF0008FF2B

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRF0008FF2B is a polymeric PTC resettable fuse from the 0ZRF series, designed for through-hole radial mounting. It features an 80 mA hold current and a 190 mA trip current, with a maximum voltage rating of 60 VDC. The device exhibits a low initial resistance of 4 Ohms minimum and a maximum post-trip resistance of 16 Ohms. It supports a maximum fault current of 3 A and operates within a temperature range of -40°C to +85°C. Packaged in tape and reel format, it serves as a slow-blow circuit protection component.

Ptc Resettable Fuses Feature Summary

• Polymeric positive temperature coefficient (PPTC) technology provides automatic reset functionality after fault clearance.
• Radial leaded construction facilitates standard through-hole PCB integration.
• Slow-blow characteristic allows tolerance for temporary inrush currents without nuisance tripping.

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection of communication ports and data lines
• Battery pack circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix FF2B corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 60V DC rating aligns with the system's operating voltage and transient conditions. Ensure the 80mA hold current meets the continuous load requirements of the protected circuit under all expected ambient temperature conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a through-hole solution is mandatory for mechanical stability or existing board layout constraints. The 0ZRF series offers a balance of low resistance and high fault current capability compared to smaller surface mount alternatives. Consider the thermal derating characteristics if the application environment exceeds standard room temperature conditions.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRF series, which specializes in radial PTC fuses for general-purpose circuit protection. The series is characterized by its ability to handle significant fault currents while maintaining low impedance during normal operation. It complements Bel's broader portfolio of polymer circuit protection devices designed for consumer electronics and industrial applications.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 80mA hold current, 60V rating, and radial package dimensions. Verify that alternative components offer comparable trip current ratios and post-trip resistance limits to ensure equivalent circuit behavior.
