Ptc Resettable Fuses Procurement Notes

Verify the specific package type and lead configuration against the official Littelfuse datasheet before procurement. Confirm that the 15 V voltage rating and 2.6 A holding current align with the target circuit requirements. Ensure compatibility with the intended manufacturing process, particularly regarding the surface-mount or strap mounting style. Cross-reference the part number suffix to confirm the exact variant matches the design specifications.

Ptc Resettable Fuses Selection Notes

Select this component when a resettable fuse with a 15 V maximum voltage and 2.6 A holding current is required. Consider the 2.5 W power dissipation capability for thermal management in the application environment. Evaluate the physical footprint of 20.9 mm length and 1 mm height for board space constraints. Ensure the application involves AC-DC or DC-DC conversion where rapid recovery after fault clearance is beneficial.

Ptc Resettable Fuses Part Context

The 15LR260U belongs to the PolySwitch family of resettable fuses from Littelfuse. These devices are engineered for automotive, telecom, and general power supply applications. Unlike traditional fuses, they offer reusable protection by automatically resetting once the fault condition is removed and the device cools down. This series supports various mounting options including surface-mount and battery-strap configurations.
