PTSLR18126V190

Ptc Resettable Fuses Overview

The PTSLR18126V190 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse manufactured by Eaton Electronics. Designed for low-voltage circuit protection, this component operates within a maximum voltage rating of 6 V and features a hold current of 1.9 A with a trip current of 3.8 A. It is housed in a compact 1812 package, measuring 4.73 mm in length, 3.41 mm in width, and 1.2 mm in height. The device exhibits a maximum resistance of 1 mOhm and can withstand fault currents up to 50 A. It functions reliably across an operating temperature range from -40°C to +85°C.

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix '190' against official Eaton documentation to confirm the precise 1.9 A hold current rating. Ensure the selected variant matches the required 6 V maximum voltage and 1812 package dimensions for your design. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile, surface-mount solution is required for circuits operating at 6 V or less. The 1.9 A hold current suits applications needing moderate continuous current with rapid response to overcurrent events. Consider the 1812 footprint constraints and thermal dissipation requirements during layout.

Ptc Resettable Fuses Part Context

This part belongs to the PTSLR series of resettable fuses, which are engineered for robust protection in space-constrained environments. The 1812 form factor allows for dense PCB mounting while maintaining high current handling capabilities typical of Eaton's industrial-grade protection components.

Ptc Resettable Fuses Replacement Considerations

Consult Eaton's official cross-reference guides for verified substitutes. Generic PPTC fuses may not match the specific tripping characteristics or mechanical tolerances of the PTSLR series.
