PTSLR18126V260

Ptc Resettable Fuses Overview

The PTSLR18126V260 is a surface-mount polymeric positive temperature coefficient (PPTC) resettable fuse from the Eaton Electronics PTSLR series. Designed for circuit protection, this component operates within a voltage range of up to 6 VDC and maintains a holding current of 2.6 A. It trips at a current of 6 A and can withstand a maximum fault current of 50 A. The device features a low resistance of 24 mOhms and is housed in an 1812 package measuring 4.73 mm by 3.41 mm with a height of 0.7 mm. It functions reliably between -40°C and +85°C.

Ptc Resettable Fuses Feature Summary

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix codes against official Eaton documentation to ensure exact electrical ratings and packaging configurations match project requirements. Confirm RoHS compliance status and moisture sensitivity level handling procedures prior to assembly. Cross-reference datasheet revisions to validate performance parameters for the specific manufacturing batch.

Ptc Resettable Fuses Selection Notes

Select this component when designing low-voltage circuits requiring resettable overcurrent protection with minimal space consumption. Ensure the operating current remains below the 2.6 A hold rating while accounting for ambient temperature derating curves. Verify that the 6 VDC maximum voltage rating aligns with the system supply to prevent dielectric breakdown during fault conditions.

Ptc Resettable Fuses Part Context

This part belongs to the PTSLR series of PPTC resettable fuses manufactured by Eaton Electronics. These components are engineered for high-reliability applications where traditional fusible links are impractical due to maintenance requirements. The series utilizes polymer technology to provide consistent trip characteristics across varying environmental conditions.

Ptc Resettable Fuses Replacement Considerations

Consult official Eaton substitution guides for direct equivalents. Generic replacements may differ in trip time characteristics or physical dimensions. Verify compatibility with existing PCB footprints and thermal management strategies before implementing alternative parts.
