0ZRF0015FF2B

Ptc Resettable Fuses Overview

The Bel Fuse Inc. 0ZRF0015FF2B is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It features a maximum voltage rating of 60V and a hold current (Ih) of 150 mA. The device trips at 300 mA with a typical trip time of 2.5 seconds. Initial resistance is typically 4 Ohms, rising to a maximum of 16 Ohms after tripping. It supports a maximum fault current of 3 A and operates within a temperature range of -40°C to +85°C. The component utilizes a radial, disc-style through-hole package.

Ptc Resettable Fuses Feature Summary

• Polymer-based self-resetting mechanism provides automatic circuit restoration after fault clearance
• Radial leaded construction facilitates standard through-hole mounting processes
• Certified by cURus and TUV agencies for international safety compliance

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection of peripheral interfaces such as USB and IEEE-488 ports

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure correct electrical ratings and packaging format. Confirm that the procurement channel provides authentic components with traceable documentation. Check for any recent product change notices regarding manufacturing origin or material composition updates prior to finalizing orders.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, through-hole solution is required for low-voltage DC circuits. Ensure the operating environment remains within the specified -40°C to +85°C range. Verify that the expected load current stays below the 150 mA hold current threshold to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRF series of polymeric resettable fuses from Bel Fuse Inc. The series is characterized by compact radial packages suitable for space-constrained applications. These devices serve as reusable alternatives to traditional one-time fusible links, offering cost-effective protection in consumer electronics and industrial control systems.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 60V voltage rating, 150 mA hold current, and radial disc package dimensions. Verify that alternative parts maintain equivalent trip characteristics and certification status.
