0ZRF0012FF2B

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRF0012FF2B is a radial PPTC resettable fuse from the 0ZRF series. It features a hold current of 120 mA and a trip current of 480 mA. The device supports maximum voltages of 60V AC or DC with a maximum fault current rating of 3 A. Initial resistance is typically 4 Ohms, rising to a maximum of 16 Ohms after tripping. It operates within a temperature range of -40°C to +85°C and utilizes a radial disk package.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through polymer positive temperature coefficient technology
• Offers dual certification for UL and TUV safety standards
• Designed for through-hole mounting with radial leads

Ptc Resettable Fuses Applications

• Overcurrent protection in industrial control systems

Ptc Resettable Fuses Procurement Notes

Verify the specific ordering suffix FF2B corresponds to tape and reel packaging when sourcing. Confirm that the 60V rating aligns with system voltage requirements. Ensure compatibility with through-hole assembly processes. Check RoHS compliance status for environmental regulations. Validate lead spacing dimensions against PCB layout specifications.

Ptc Resettable Fuses Selection Notes

Select this component for applications requiring moderate holding currents around 120 mA. The 60V rating suits low-voltage DC circuits. Consider the higher initial resistance compared to lower-voltage series variants. Evaluate thermal derating requirements for high ambient temperatures. Ensure the trip current of 480 mA provides adequate margin for normal operating surges.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRF series of radial PTC resettable fuses. The series is designed for general-purpose overcurrent protection in consumer and industrial electronics. It complements other Bel Fuse offerings like the 0ZRE and 0ZCJ series, which offer different voltage ratings and form factors such as surface mount options.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRF series parts with identical electrical characteristics but different packaging or lead configurations. Verify that any replacement maintains the 120 mA hold current and 60V maximum voltage rating. Ensure the alternative part meets the same UL and TUV certification requirements.
