SMD1210P110TSA

Ptc Resettable Fuses Overview

The Littelfuse SMD1210P110TSA is a POLYFUSE resettable PPTC device in a 1210 surface-mount package. It features a hold current of 1.1 A and a trip current of 2.2 A. The component supports a maximum voltage rating of 16 V DC and withstands fault currents up to 100 A. Initial resistance is typically low, rising significantly upon activation. It operates within a temperature range of -40°C to +85°C.

Ptc Resettable Fuses Feature Summary

• Provides automatic overcurrent protection by increasing resistance during fault conditions
• Offers reliable circuit safeguarding without requiring manual replacement after tripping
• Designed for direct surface-mount integration onto printed circuit boards

Ptc Resettable Fuses Applications

• Consumer electronics circuit protection
• Portable device power line safeguarding
• Battery pack overcurrent prevention

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'TSA' against official Littelfuse documentation to confirm tape-and-reel packaging details. Confirm RoHS compliance status through the manufacturer datasheet. Ensure the part number matches the exact electrical ratings required for the target application circuit design.

Ptc Resettable Fuses Selection Notes

Select this component when a 1.1 A hold current and 16 V rating are required for space-constrained designs. Compare initial resistance values against other 1210 series parts if low standby power loss is critical. Verify that the 100 A fault current capability aligns with the system's potential short-circuit levels.

Ptc Resettable Fuses Part Context

This device belongs to the POLYFUSE SMD-P series of resettable fuses. These components utilize polymer technology to provide reusable overcurrent protection. The 1210 form factor allows for compact PCB layouts while maintaining robust electrical performance standards for general electronic applications.

Ptc Resettable Fuses Replacement Considerations

Check Littelfuse documentation for cross-reference data. Verify that any substitute maintains identical 1210 dimensions, 1.1 A hold current, and 16 V rating to ensure mechanical and electrical compatibility.
