SMDL0402B010TF

Ptc Resettable Fuses Overview

The YAGEO SMDL0402B010TF is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for surface mount technology. It belongs to the SMDL0402 series and utilizes a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.32 mm height. The component features a maximum voltage rating of 6 VDC and a hold current of 100 mA. It trips at a minimum current of 300 mA within one second. The device offers low resistance characteristics and provides overcurrent protection for sensitive electronic circuits.

Ptc Resettable Fuses Feature Summary

• Polymeric PPTC technology for automatic circuit recovery after fault clearance
• Low profile 0402 surface mount package for compact board layouts
• High reliability construction suitable for consumer and industrial electronics
• Inherent latching action eliminates need for manual reset or replacement

Ptc Resettable Fuses Applications

• Overcurrent protection in portable consumer electronics
• Protection interfaces for USB and data communication ports
• Battery pack safeguarding in mobile devices
• Circuit protection for small form factor industrial modules

Ptc Resettable Fuses Procurement Notes

Verify that the selected component matches the specific 6VDC and 100mA hold current requirements of the target circuit design. Confirm compatibility with standard reflow soldering profiles used for 0402 packages. Ensure that the trip current specifications align with the operational limits of the protected load to prevent nuisance tripping during normal operation.

Ptc Resettable Fuses Selection Notes

Choose this component when space constraints require a 0402 footprint and low operating voltages are present. Consider the thermal environment, as ambient temperature affects hold current performance. Evaluate the maximum fault current the device must withstand without damage. Compare against alternative resettable fuses if higher voltage ratings or different package sizes are necessary for the application.

Ptc Resettable Fuses Part Context

This part is a passive circuit protection element manufactured by YAGEO. It functions as a self-healing fuse, contrasting with traditional one-time fusible links. The SMDL series is engineered for high-volume surface mount assembly processes. It serves as a critical safety component in modern electronics where maintenance access is limited or impossible.

Ptc Resettable Fuses Replacement Considerations

Direct substitutes must match the 6VDC voltage rating, 100mA hold current, and 0402 package dimensions. Verify that any alternative PPTC device has comparable trip time characteristics and maximum fault current ratings. Ensure the replacement maintains the same thermal derating curves for reliable operation.
