Inrush Current Limiters (ICL) Procurement Notes

Verify the specific thermal class and mounting requirements against the application schematic. Confirm that the steady-state current rating of 200 mA aligns with the circuit's operational limits. Ensure the lead spacing matches the PCB layout constraints before finalizing the order.

Inrush Current Limiters (ICL) Selection Notes

Select this component when the circuit requires a 200 Ohm initial resistance to limit startup currents. The 200 mA steady-state rating defines the continuous load capacity. Consider the 9.00 mm diameter for available board space and thermal dissipation needs relative to other series options.

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, offering a reliable method to curb transient currents without requiring complex active control circuitry.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 200 Ohm resistance, 200 mA current rating, and 9.00 mm diameter. Verify compatibility with existing thermal profiles and mechanical mounting constraints when evaluating alternative manufacturers or series.
