Inrush Current Limiters (ICL) Procurement Notes

Verify the obsolete status indicated by TTI before procurement planning. Confirm availability through distributors like Mouser or DigiKey, noting that lead times may vary significantly due to stock levels. Ensure the specific ordering suffix matches the required resistance tolerance and package dimensions for integration.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 40 Ohm initial resistance is required for inrush limiting. Verify that the 15 mm body size fits the PCB layout constraints. Ensure the circuit design accounts for the 4 A steady-state current capability and the thermal characteristics of the NTC material during operation.
