0ZRC0110FF2B

Ptc Resettable Fuses Overview

The Bel Fuse Inc. 0ZRC0110FF2B is a polymeric PTC resettable fuse designed for overcurrent protection in electronic circuits. It features a hold current of 1.1 A and a trip current of 2.2 A, with a maximum voltage rating of 90 VDC. The component has an initial resistance of 150 mOhms minimum and a post-trip resistance of 380 mOhms maximum. It supports a maximum fault current of 40 A and trips within 8.2 seconds under specified conditions. The device operates within a temperature range of -40°C to +85°C and utilizes a radial disc package measuring 13.00 mm in length, 3.10 mm in width, and up to 18.00 mm in height.

Ptc Resettable Fuses Feature Summary

• Self-resetting polymeric positive temperature coefficient construction eliminates the need for manual replacement after fault clearance.
• Radial disc form factor enables through-hole mounting on printed circuit boards for robust mechanical attachment.
• Slow-blow response characteristic provides tolerance for transient inrush currents while protecting against sustained overloads.

Ptc Resettable Fuses Applications

• Overcurrent protection for portable consumer electronics
• Circuit safeguarding in telecommunications equipment
• Power supply input protection for industrial control systems

Ptc Resettable Fuses Procurement Notes

Verify that the procurement source explicitly confirms the Radial Disc package style and 90V voltage rating, as these are critical differentiators from surface-mount variants. Ensure the supplier documentation matches the specific 0ZRC series designation to avoid confusion with similar 0ZCF or 0ZRR models. Request RoHS compliance certificates if required for your manufacturing process. Confirm the component is new and free from moisture damage, as indicated by its humidity sensitivity classification.

Ptc Resettable Fuses Selection Notes

Select this component when a through-hole solution is required for circuits operating at voltages up to 90 VDC. The 1.1 A hold current makes it suitable for low-power applications where precise current limiting is necessary. Consider the 18.00 mm seated height during PCB layout to ensure adequate clearance. The slow-blow nature allows it to withstand temporary current spikes without nuisance tripping, making it ideal for loads with high startup currents.

Ptc Resettable Fuses Part Context

This part belongs to the Bel Fuse 0ZRC series of polymeric resettable fuses. Unlike surface-mount options, the 0ZRC series is specifically engineered for through-hole assembly, offering higher mechanical stability. It shares the self-resetting functionality common to PPTC devices but distinguishes itself with a higher voltage rating compared to many standard low-voltage SMD fuses.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 1.1 A hold current, 90 VDC rating, and radial disc package. Verify that any alternative component maintains the same 40 A max current capability and thermal performance characteristics to ensure circuit integrity.
