0ZRM0135FF1A

Ptc Resettable Fuses Overview

The 0ZRM0135FF1A is a resettable polymeric positive temperature coefficient (PPTC) device manufactured by Bel Fuse. It belongs to the 0ZRR series and functions as a slow-blow fuse with a holding current of 1.35 A and a trip current of 2.7 A. The component supports a maximum voltage of 60 VDC and has a maximum rated current of 40 A. Its initial resistance is 300 Ohms, and it operates within a temperature range of -40°C to +85°C. The physical dimensions are 14.5 mm in diameter and 3.1 mm in height. It is supplied in bulk packaging.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through reversible tripping action upon overcurrent conditions
• Designed for slow-blow response characteristics to tolerate temporary inrush currents
• Constructed from polymeric materials that increase resistance significantly when heated

Ptc Resettable Fuses Applications

• Overcurrent protection for low-voltage DC power distribution lines
• Protection circuits in consumer electronic devices requiring 60 VDC limits
• Battery-powered equipment safeguarding against short-circuit faults

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF1A corresponds to the required bulk packaging configuration rather than reel or cut tape options. Confirm that the 1.35 A holding current aligns with the operational load requirements without causing nuisance tripping during normal operation. Ensure the 300 Ohms initial resistance is acceptable for the target circuit design constraints.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded PPTC device is required for 60 VDC applications with a 1.35 A steady-state current. Consider the 14.5 mm diameter for adequate spacing on the printed circuit board. Evaluate the thermal environment to ensure the operating temperature remains within the specified -40°C to +85°C range for reliable performance.

Ptc Resettable Fuses Part Context

This part is part of the Bel Fuse 0ZRR series of resettable fuses. It serves as a reusable alternative to traditional one-time fusible links. The device utilizes polymer technology to provide protection in compact form factors suitable for various electronic assemblies where space and cost efficiency are prioritized alongside safety compliance.

Ptc Resettable Fuses Replacement Considerations

The 0ZRR0135FF1A is an electrically equivalent variant of the 0ZRM0135FF1A, differing primarily in packaging format. Verify if reel or bulk supply preferences dictate the choice between these two part numbers while maintaining identical electrical specifications.
