Inrush Current Limiters (ICL) Procurement Notes

Verify the specific lead wire configuration and tolerance requirements against the official datasheet before procurement. Ensure the 5A current rating and 7-ohm resistance align with the target circuit design parameters to prevent component failure or inadequate surge protection.

Inrush Current Limiters (ICL) Selection Notes

Select this component when managing high initial surge currents in AC or DC circuits. The 7-ohm resistance value is critical for limiting peak current, while the 5A rating defines the continuous operational limit. Consider the physical dimensions and lead style for PCB or panel mounting constraints.

Inrush Current Limiters (ICL) Part Context

Part of the Amphenol Advanced Sensors CL series, which specializes in negative temperature coefficient (NTC) thermistors for inrush current limiting. These components are engineered to protect sensitive electronic components from damage caused by high initial charging currents.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official substitution lists for equivalent NTC inrush limiters with matching 7-ohm resistance and 5A current ratings. Verify that alternative parts maintain similar kinked lead configurations and thermal characteristics for direct compatibility.
