PTSLR12106V400

Ptc Resettable Fuses Overview

The PTSLR12106V400 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the Eaton Bussmann PTSLR series. It features a 1210 (3225 metric) package with dimensions of 3.43 mm length, 2.8 mm width, and 1.2 mm height. The device has a maximum voltage rating of 6 VDC, a hold current of 4 A, and a trip current of 8 A. It supports a maximum fault current of 50 A and exhibits a typical resistance of 14 mOhms. Operating within a temperature range of -40°C to +85°C, it dissipates up to 800 mW.

Ptc Resettable Fuses Feature Summary

• Provides overcurrent protection through automatic resistance increase during fault conditions
• Enables circuit recovery without manual replacement after fault clearance
• Designed for direct surface mounting on printed circuit boards

Ptc Resettable Fuses Applications

• Portable electronic device circuit protection
• Battery pack overcurrent safeguarding
• Low-voltage data line surge protection

Ptc Resettable Fuses Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number PTSLR12106V400 with official Eaton documentation. Confirm RoHS compliance status and moisture sensitivity classification prior to assembly. Ensure storage conditions adhere to humidity limits specified in the datasheet to maintain reliability. Validate that the selected packaging format matches production requirements.

Ptc Resettable Fuses Selection Notes

Select this component when low operating voltage and high holding current are required for space-constrained designs. The 1210 footprint accommodates higher current loads compared to smaller packages. Verify that the system's normal operating current remains below the 4 A hold current threshold while ensuring fault currents do not exceed the 50 A maximum rating for safe operation.

Ptc Resettable Fuses Part Context

This device belongs to the PTSLR series of resettable fuses manufactured by Eaton Electronics. The series utilizes polymeric technology to provide reliable circuit protection in compact form factors. These components serve as alternatives to traditional fusible links in modern electronics where maintenance-free operation and repeated fault tolerance are essential design criteria.

Ptc Resettable Fuses Replacement Considerations

Compatible substitutes include PTSLR12106V500 for higher current capacity or PTSLR12106V300 for lower current applications. Ensure replacement parts match the 1210 package dimensions and 6 VDC voltage rating. Verify that alternative PPTC devices maintain similar thermal characteristics and trip time specifications.
