PFUF.110.2

Ptc Resettable Fuses Overview

The PFUF.110.2 is a surface-mount polymer PTC resettable fuse from the Schurter PFUF series, designed for high-reliability overcurrent protection in compact electronic assemblies. It features a 1210 package with a maximum operating voltage of 6 VDC and a hold current of 1.1 A. The device trips at 2.2 A and withstands fault currents up to 40 A, exhibiting an initial resistance of 210 mΩ. It operates reliably within a temperature range of -40°C to +85°C and has a profile height of 2.8 mm.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit recovery after fault clearance without manual replacement
• Offers reliable overcurrent protection through positive temperature coefficient polymer technology
• Designed for direct surface mounting on printed circuit boards

Ptc Resettable Fuses Applications

• Portable consumer electronics requiring compact overcurrent protection
• Battery-powered devices needing resettable safety components
• Low-voltage industrial control circuits

Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number PFUF.110.2 with official Schurter documentation. Confirm that the received items match the specified 1210 SMD package and 1.1 A hold current rating. Ensure compliance with required environmental specifications for the intended application environment.

Ptc Resettable Fuses Selection Notes

Select this component when low-profile surface-mount protection is required for circuits operating at 6 VDC or less. The 1.1 A hold current suits applications with moderate steady-state loads, while the 2.2 A trip point provides necessary margin against transient surges. Consider the 210 mΩ resistance impact on power efficiency during normal operation.

Ptc Resettable Fuses Part Context

This component belongs to the PFUF series of polymer PTC fuses manufactured by Schurter. The series specializes in surface-mount resettable fuses tailored for space-constrained modern electronics. The PFUF.110.2 represents a specific variant within this lineup, distinguished by its 1.1 A current rating and 1210 footprint dimensions.

Ptc Resettable Fuses Replacement Considerations

Consult official Schurter substitution guides for verified equivalents. Do not assume functional interchangeability with generic PTC thermistors due to specific trip characteristics and voltage ratings.
