0ZRE0012FF2C

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRE0012FF2C is a radial leaded PPTC resettable fuse from the 0ZRE series. It features a hold current of 120 mA and a trip current of 300 mA. The device supports maximum voltages of 240 VAC and 240 VDC. Initial resistance is 12 mOhms. Operating temperature ranges from -40°C to +85°C. It is packaged in tape and reel or cut tape formats.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through polymer positive temperature coefficient technology
• Offers repeatable reset functionality after fault conditions clear
• Designed for slow blow response characteristics

Ptc Resettable Fuses Applications

• Overcurrent protection for electronic circuits
• Power supply input protection
• Signal line protection

Ptc Resettable Fuses Procurement Notes

Verify the specific package variant, as the part number indicates availability in both tape and reel and cut tape configurations. Confirm that the voltage rating aligns with the system's AC or DC requirements. Ensure the hold current meets the operational load specifications without nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Select this component when a radial leaded form factor is required for through-hole mounting. The 120 mA hold current suits low-power signal lines. Verify that the 240 V rating covers the peak operating voltage. Consider thermal derating at elevated ambient temperatures near the upper limit.

Ptc Resettable Fuses Part Context

This component belongs to the 0ZRE series of radial PPTC fuses by Bel Fuse. The series provides general-purpose overcurrent protection. It utilizes polymer technology to balance low initial resistance with high trip sensitivity. The radial design facilitates standard PCB assembly processes.

Ptc Resettable Fuses Replacement Considerations

Cross-reference other 0ZRE series parts with matching 120 mA hold current and 240 V rating. Verify physical dimensions and lead spacing compatibility before substitution.
