Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation (e.g., 10/13) against official Cantherm documentation to ensure correct resistance and current ratings. Confirm package dimensions and lead configuration match system requirements. Request manufacturer datasheets for precise thermal and electrical characteristics before finalizing procurement decisions.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on required steady-state resistance and peak current handling capabilities. Ensure the operating temperature range aligns with the application environment. Consider physical size constraints regarding the 15 mm diameter and 30 mm length. Validate thermal dissipation coefficients for long-term reliability under continuous load conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the MF73T series of inrush current limiters from Cantherm. Variants within this series differ primarily in resistance values and current ratings, such as the 10/8 or 10/15 models. The MF73T-1 designation indicates a standard NTC thermistor construction optimized for industrial power applications requiring reliable surge protection.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Cantherm MF73T variants with matching electrical parameters, such as the MF73T-1 10/8 or MF73T-1 10/15. Cross-brand replacements require careful verification of resistance, current rating, and physical dimensions to ensure functional compatibility without redesigning the host circuit.
