Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version, as some sources indicate a 3A rating while others specify 4A. Confirm the package style matches the target footprint. Check RoHS compliance status directly from the manufacturer's documentation before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 40 Ohm nominal resistance is required for inrush limiting. Ensure the circuit's operating current does not exceed the rated limit. Consider the 15mm body size for adequate spacing on the printed circuit board layout during the design phase.

Inrush Current Limiters (ICL) Part Context

This part belongs to the NT series of inrush current limiters manufactured by YAGEO. These components are distinct from standard resistors or capacitors, serving specifically to protect sensitive downstream components from high initial current spikes upon power application.

Inrush Current Limiters (ICL) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult official distributor catalogs for equivalent NTC inrush limiters with matching resistance and current ratings.
