Ptc Resettable Fuses Procurement Notes

Verify the specific Littelfuse datasheet revision to confirm exact parameter tolerances and compliance status. Ensure the procurement source provides authentic components with traceable manufacturing lot codes. Cross-reference the part number against official Littelfuse catalogs to avoid counterfeit substitutions. Confirm packaging format matches production requirements.

Ptc Resettable Fuses Selection Notes

Select this component when a radial lead configuration is required for through-hole mounting on printed circuit boards. Choose based on the 1.1 A holding current and 72 VDC maximum voltage limits. Consider the 380 mOhms resistance for low-power loss applications. Evaluate thermal derating curves for high-temperature environments exceeding standard ratings.

Ptc Resettable Fuses Part Context

This part belongs to the RXEF series of PolySwitch resettable fuses manufactured by Littelfuse. The series utilizes polymer positive temperature coefficient technology for self-resetting protection. It serves as a reusable alternative to traditional one-time fusible links in electronic circuit designs requiring robust overcurrent management.

Ptc Resettable Fuses Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board layouts before attempting substitution. Consult Littelfuse technical support for direct equivalents if the RXE110-2 is unavailable.
