Ptc Resettable Fuses datasheet and documents for 0ZRC0055FF1E

0ZRC0055FF1E

Ptc Resettable Fuses Overview

The Bel Fuse Inc. 0ZRC0055FF1E is a polymer PTC resettable fuse designed for through-hole radial mounting. It features a maximum holding current of 500 mA and a maximum trip current of 1 A. The device supports a maximum voltage of 90 VDC with a rated interrupting current of up to 40 A. Initial resistance is specified at 1.17 Ohms, operating within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

Polymer positive temperature coefficient technology enables automatic circuit protection by increasing resistance during overcurrent events.
Radial leaded construction facilitates standard through-hole PCB integration.
Slow-blow characteristic provides tolerance against transient inrush currents without nuisance tripping.

Ptc Resettable Fuses Applications

Overcurrent protection for low-voltage DC electronic circuits
Battery pack protection in portable devices
Peripheral interface circuit safeguarding

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF1E corresponds to the bulk packaging configuration as documented. Confirm that the 90 VDC rating aligns with the target application voltage requirements. Ensure compatibility with the -40°C to +85°C operational temperature range for the intended environment.

Ptc Resettable Fuses Selection Notes

Select this component when a radial through-hole PTC fuse is required for 90 VDC systems. The 500 mA holding current suits moderate load protection needs. Verify that the 1.17 Ohms initial resistance does not exceed allowable voltage drop constraints in the design.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRC series of polymer PTC resettable fuses manufactured by Bel Fuse Inc. The series is characterized by radial leads and specific voltage ratings suitable for general-purpose circuit protection applications requiring reliable overcurrent interruption capabilities.

Ptc Resettable Fuses Replacement Considerations

Cross-reference with other 0ZRC series variants for different current or voltage ratings. Verify package compatibility and electrical parameters before substituting with generic PTC components.
