0ZRM0025FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRM0025FF1E is a radial leaded Polymeric Positive Temperature Coefficient (PPTC) resettable fuse belonging to the 0ZRM series. It features a hold current of 250 mA and a trip current of 500 mA, designed for operation at maximum voltages of 120 VAC or 120 VDC. The device exhibits a low initial resistance of 3 mOhms and functions as a slow-blow protection component. It operates within a temperature range of -40°C to +85°C and is supplied in bulk packaging.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection against overcurrent conditions through self-resetting PPTC technology
• Offers dual voltage rating capability for both AC and DC applications up to 120V
• Features radial leaded construction suitable for through-hole mounting on printed circuit boards

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in consumer electronics and peripherals
• Battery pack safeguarding in mobile equipment

Ptc Resettable Fuses Procurement Notes

Verify that the specific suffix '1E' corresponds to the bulk packaging configuration rather than tape and reel variants. Confirm RoHS compliance status via the manufacturer's official documentation before integration. Ensure the selected variant matches the required hold and trip current specifications for the target application circuit design.

Ptc Resettable Fuses Selection Notes

Select this component when a through-hole solution is required for low-current protection scenarios. The 250 mA hold current makes it suitable for sensitive signal lines or low-power data interfaces. Consider the slow-blow characteristic to tolerate temporary inrush currents without nuisance tripping during normal operation cycles.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRM family of radial PPTC resettable fuses manufactured by Bel Fuse. The series provides cost-effective overcurrent protection solutions for various electronic assemblies. The 0ZRM designation indicates a standard polymer fuse with radial leads, distinguishing it from surface mount alternatives like the 0ZCH or 0ZCG series.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRM series parts with identical electrical ratings, such as 0ZRM0025FF2B if bulk packaging is not strictly required. Verify that any replacement maintains the same 120VAC/120VDC voltage rating and 250mA hold current specification.
