Inrush Current Limiters (ICL) Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration. Confirm that the thermal environment and steady-state current requirements align with the component's 1 A rating. Ensure compatibility with the target AC voltage range of 120 to 240 V. Check for RoHS compliance status if required by project specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this model when a 5 Ohm initial resistance is required to limit inrush current for loads up to 1 A. Consider the physical dimensions of 7.00 mm diameter for board space constraints. Evaluate the thermal dissipation capabilities relative to the operating frequency and ambient temperature conditions.

Inrush Current Limiters (ICL) Part Context

This component belongs to the MF72 series of power NTC thermistors manufactured by Cantherm. The series is engineered specifically for inrush current limiting applications. These devices are widely used in various electronic systems to mitigate the high initial currents drawn by capacitive loads upon energization.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 5 Ohm resistance, 1 A current rating, and 7.00 mm diameter. Verify equivalent hot resistance and thermal time constants. Cross-reference with other MF72 variants or comparable NTC ICLs from different manufacturers ensuring identical electrical and mechanical specifications.
