0ZRM0030FF2C

Ptc Resettable Fuses Overview

The Bel Fuse 0ZRM0030FF2C is a radial leaded PolySwitch resettable PPTC fuse designed for circuit protection. It features a holding current of 300 mA and a trip current of 600 mA, operating at a maximum voltage of 120 VAC or 120 VDC. The device exhibits a typical resistance of 470 mOhms and functions within a temperature range of -40°C to +85°C. Packaged in bulk with a factory quantity of 3000 units, this slow-blow component provides reliable overcurrent protection for low-current applications.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit interruption upon detection of excessive current flow
• Restores conductivity after fault clearance without manual replacement
• Offers dual rating compatibility for both AC and DC voltage systems

Ptc Resettable Fuses Applications

• Portable electronic devices requiring compact overcurrent protection
• Peripheral equipment interfaces such as USB ports
• Battery-powered consumer electronics circuits

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix FF2C confirms the bulk packaging format, as other suffixes may indicate tape-and-reel configurations. Confirm that the 120V rating aligns with your system's maximum operating voltage. Ensure the radial lead style matches your PCB hole layout requirements. Cross-reference the datasheet for derating curves applicable to your ambient temperature conditions.

Ptc Resettable Fuses Selection Notes

Select this component when a radial through-hole solution is preferred over surface mount alternatives. The 300mA holding current suits low-power signal lines rather than high-current power rails. Consider the slower response time inherent to this series compared to fast-acting fuses. Evaluate space constraints on the board to accommodate the lead length and body diameter.

Ptc Resettable Fuses Part Context

This part belongs to the 0ZRM series of radial resettable fuses from Bel Fuse. It serves as a reusable alternative to traditional one-time fusible links. The series is engineered for cost-effective protection in mass-produced consumer goods. It complements surface mount options like the 0ZCG series for mixed technology assemblies.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes include other 0ZRM series variants with matching electrical ratings. Verify physical dimensions against existing footprints before substitution. Alternative brands may require adjustments to mounting orientation due to lead spacing differences.
