Ptc Resettable Fuses Procurement Notes

Verify the specific suffix (e.g., F) when ordering, as it may indicate packaging or tape-and-reel variations not altering electrical function. Confirm RoHS compliance status via the official datasheet. Ensure the selected variant matches the required strap mount style and SMD termination type for proper PCB integration.

Ptc Resettable Fuses Selection Notes

Select this component based on the 2 A hold current and 30 VDC maximum voltage requirements. The low resistance value supports minimal voltage drop in high-current paths. Verify that the 100 A fault current rating exceeds potential surge levels in the target application to ensure reliable tripping without damage.

Ptc Resettable Fuses Part Context

This part belongs to the SRP series of PolySwitch resettable fuses from Littelfuse. These devices utilize polymer positive temperature coefficient technology to provide reusable circuit protection. The series is engineered for applications requiring robust overcurrent defense in compact form factors.
