Inrush Current Limiters (ICL) Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the steady-state current rating and physical lead spacing match the target PCB layout requirements. Ensure compliance with relevant safety certifications such as UL or VDE if required by the end application standards.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the peak inrush current magnitude and the required steady-state operating current. Evaluate the thermal dissipation capabilities within the enclosure. Compare the physical footprint constraints against the 13.00mm diameter specification. Consider the B-value characteristics if temperature monitoring is integrated into the design logic.

Inrush Current Limiters (ICL) Part Context

This part belongs to the MF72 series of power NTC thermistors manufactured by Cantherm. The series is engineered specifically for inrush current limiting applications. These components utilize ceramic semiconductor materials to provide high resistance at low temperatures, which decreases as current flows and heats the element.
