0ZRM0017FF2C

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRM0017FF2C is a radial leaded polymer PTC self-resettable fuse designed for circuit protection. It features a hold current of 170 mA and a trip current of 340 mA, operating at a maximum voltage of 120 VAC or 120 VDC. The device has a minimum initial resistance of 2 Ohms and a maximum resistance after tripping of 7 Ohms. It supports a maximum fault current of 2 A with a trip time of 10 seconds. The component is packaged in tape and reel format, suitable for automated assembly processes.

Ptc Resettable Fuses Feature Summary

• Radial leaded polymer construction for through-hole mounting
• Self-resetting functionality eliminates need for manual replacement
• AEC-Q200 qualified for automotive grade reliability standards

Ptc Resettable Fuses Applications

• Automotive electronics circuit protection
• Consumer electronic device overcurrent safeguarding
• Industrial control system input/output protection

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2C confirms the tape and reel packaging configuration, as standard variants may differ. Confirm RoHS3 compliance status directly with the manufacturer documentation prior to integration. Ensure the ordering quantity aligns with the factory pack quantity of 2000 units to avoid partial reel handling issues during production assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a low holding current near 170 mA is required for sensitive circuit protection. The radial package facilitates easy insertion into PCB layouts where surface mount options are insufficient. Consider the 120V rating for compatibility with lower voltage AC/DC systems requiring resettable protection without frequent maintenance.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRM series of resettable fuses from Bel Fuse. The series offers various hold currents and voltage ratings tailored for different protection needs. The 0ZRM0017FF2C specifically targets applications needing precise low-current protection with automotive qualification, distinguishing it from general-purpose industrial fuses in the broader portfolio.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes within the same series include 0ZRM0025FF2C for higher current requirements. Cross-series alternatives like 0ZRR or 0ZLP offer different voltage or package configurations but require re-evaluation of thermal and electrical constraints.
