0ZRM0017FF1E

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRM0017FF1E is a radial PPTC resettable fuse designed for circuit protection. It features a hold current of 170 mA and a trip current of 340 mA, ensuring reliable operation under normal conditions while responding to overcurrent events. The device supports maximum voltages of 120 VAC and 120 VDC. With an initial resistance of 7 mOhms, it minimizes power loss in the circuit. The component operates within a temperature range of -40°C to +85°C and is packaged in bulk quantities.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault clearance without manual replacement
• Offers dual voltage rating capability for both AC and DC applications
• Features low initial resistance to reduce power dissipation during normal operation

Ptc Resettable Fuses Applications

• Overcurrent protection for portable electronic devices
• Protection circuits in automotive electronics systems
• Industrial control equipment requiring resettable fusing
• Consumer appliance power input stages

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '1E' corresponds to the bulk packaging configuration rather than tape and reel variants. Confirm that the 170 mA hold current aligns with the target circuit's continuous load requirements. Ensure the 120 VAC/VDC rating meets the system's maximum operating voltage constraints. Check RoHS compliance status if restricted substances are prohibited in the final assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded form factor is required for through-hole mounting. Choose the 0ZRM series for applications needing higher voltage ratings compared to lower-voltage PPTC alternatives. Consider the slow-blow characteristic for circuits with temporary inrush currents. Evaluate the physical dimensions against available PCB space constraints before finalizing the design.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRM series of polymer resettable fuses from Bel Fuse. The series is characterized by its ability to handle high voltage ratings up to 120V while maintaining compact radial packages. It serves as a reusable alternative to traditional one-time fusible links in modern electronic designs.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other Bel Fuse 0ZRM series parts with matching electrical parameters. Verify that any replacement maintains the same radial package style and lead spacing. Cross-reference trip current and voltage ratings to ensure equivalent protection levels.
