Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'UAF' against official Littelfuse documentation to confirm package style and tape-and-reel specifications. Ensure that the selected component meets the required thermal derating curves for the intended operating environment. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before finalizing procurement orders.

Ptc Resettable Fuses Selection Notes

Select this component when a low-profile surface-mount resettable fuse is required for 16VDC circuits. The 1.75A holding current suits moderate load protection needs. Evaluate the 0.05 Ohm resistance for potential power loss constraints. Confirm that the 100A maximum fault current capability aligns with the system's short-circuit conditions and upstream protection coordination requirements.

Ptc Resettable Fuses Part Context

This part belongs to the VLP series of PolySwitch resettable fuses from Littelfuse. The series focuses on compact, surface-mount solutions for consumer electronics. It complements other Littelfuse protection products by offering reusable overcurrent safeguarding without manual replacement, distinguishing it from traditional one-time fusible links.

Ptc Resettable Fuses Replacement Considerations

Consult official Littelfuse substitution guides for verified alternatives. Do not assume functional equivalence with generic PPTC components based solely on electrical ratings.
