PFDF.050.2

Ptc Resettable Fuses Overview

The PFDF.050.2 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the Schurter PFDF series, designed for PCB mounting. It features a holding current of 550 mA and a trip current of 1.2 A, with a maximum voltage rating of 60 VDC. The device supports a maximum rated current of 10 A and exhibits a resistance of 1 ohm. It operates within a temperature range of -40°C to +85°C and has a height of 4.22 mm.

Ptc Resettable Fuses Feature Summary

• Provides automatic circuit protection through self-resetting PTC technology
• Designed for direct surface-mount attachment to printed circuit boards
• Offers thermal overload protection without requiring manual replacement

Ptc Resettable Fuses Applications

• Overcurrent protection in portable electronic devices
• Protection circuits for battery-powered equipment
• Signal line protection in consumer electronics

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix against official Schurter documentation to confirm exact electrical ratings and packaging configuration. Ensure compatibility with automated SMT assembly processes regarding peak reflow temperature limits. Confirm that the 60 VDC rating aligns with the target circuit design requirements before procurement.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, surface-mount solution is required for overcurrent protection. The 550 mA holding current suits applications with steady-state currents below this threshold. Consider the 1 ohm resistance impact on signal integrity or power loss in sensitive circuits during normal operation.

Ptc Resettable Fuses Part Context

This part belongs to the PFDF series of Schurter resettable fuses. These components are engineered for compact electronic designs where space constraints necessitate surface-mount technology. The series provides reliable protection against overcurrent conditions in various modern electronic assemblies.

Ptc Resettable Fuses Replacement Considerations

Consult official Schurter cross-reference documents for verified substitutes. Generic PPTC fuses may differ in physical dimensions, response times, or voltage ratings. Do not assume interchangeability without verifying all electrical and mechanical parameters.
