0ZRP0135FF2B

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRP0135FF2B is a polymeric PTC resettable fuse designed for circuit protection. It features a hold current of 1.35 A and a trip current of 2.7 A, operating at a maximum voltage of 60 VDC. The device has a maximum rated current of 40 A and an initial resistance of 300 Ohms. It operates within a temperature range of -40°C to +85°C. The component utilizes a radial through-hole package with dimensions of 14.5 mm diameter and 3.1 mm height.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection by increasing resistance during overcurrent events
• Self-resetting functionality eliminates the need for manual replacement after fault clearance
• Complies with AEC-Q200 automotive qualification standards for reliability

Ptc Resettable Fuses Applications

• Automotive electronics systems requiring AEC-Q200 compliance
• Low-voltage DC power supply input protection
• Portable electronic device circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix FF2B corresponds to the required packaging configuration, as variations exist within the product family. Confirm that the radial lead spacing matches the target PCB footprint requirements. Ensure the application environment remains within the specified -40°C to +85°C operational temperature limits to maintain performance integrity.

Ptc Resettable Fuses Selection Notes

Select this component when a self-resetting protection mechanism is preferred over traditional fuses in low-voltage applications. The 1.35 A hold current suits circuits with steady-state loads near this threshold. Consider the 300 Ohm initial resistance impact on signal lines or sensitive power rails before integration into the design scheme.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRP series of polymeric PTC resettable fuses from Bel Fuse. It shares core electrical characteristics with other variants in the series but differs in physical packaging and lead configuration. The radial disc format facilitates through-hole mounting on printed circuit boards.

Ptc Resettable Fuses Replacement Considerations

The 0ZRR0135FF2B offers identical electrical ratings but uses reel packaging instead of bulk or tape-and-reel formats suitable for automated assembly.
