Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific ordering suffix matches the required lead configuration, as options such as straight or kinked leads are available through distinct part number variations. Confirm compliance requirements against the manufacturer's documentation. Ensure thermal management considerations align with the specified dissipation constant and failure energy ratings for the target application environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state current capacity and initial resistance value. Evaluate the physical footprint constraints regarding the 10 mm diameter and 6.3 mm lead spacing. Consider the thermal performance characteristics, including the dissipation constant and time constant, to ensure reliable operation under expected load conditions and ambient temperatures.

Inrush Current Limiters (ICL) Part Context
