Inrush Current Limiters (ICL) Procurement Notes

Verify the specific part number suffix against official Cantherm documentation to ensure correct resistance and dimensional specifications. Confirm that the application environment remains within the stated operating temperature limits of -55°C to 200°C. Ensure the circuit design accounts for the steady-state current rating of 8 A to prevent thermal runaway or component failure during continuous operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required nominal resistance of 1.3 Ohms and the maximum steady-state current capacity of 8 A. Consider the physical size constraints, specifically the 17.50 mm diameter and 10.00 mm thickness, for PCB layout or chassis mounting. Verify compatibility with the system's operating temperature range and ensure the thermal characteristics align with the intended inrush current suppression requirements.

Inrush Current Limiters (ICL) Part Context

This component belongs to the MF72 series of power NTC thermistors produced by Cantherm. These devices are specialized for managing electrical surges in electronic circuits. The series offers various resistance values and physical sizes to accommodate different power levels and form factor requirements across industrial and consumer electronics applications.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other MF72 series variants such as MF72-001.5D15 if a slightly higher resistance value is acceptable. Ensure any substitute maintains the same 1.3 Ohm nominal resistance and 8 A current rating. Verify dimensional compatibility before implementation.
