Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value and tolerance code against the manufacturer's official datasheet, as variations may exist within the ICL family. Confirm that the 8.5 A steady-state rating aligns with the thermal management requirements of the target circuit design prior to final procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 10 Ohm initial resistance and 8.5 A continuous current capacity. Ensure the 28 mm diameter fits the available board space and that the 7.5 mm lead spacing matches the PCB footprint. Validate thermal dissipation capabilities under worst-case operating conditions.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of negative temperature coefficient thermistors. These components are specifically engineered for circuit protection roles where high initial resistance is needed to suppress surge currents, transitioning to low resistance during normal operation to minimize power loss.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other ICL series parts such as ICL050D25MIC or ICL680D25MIC if different resistance or current ratings are required. Verify that any substitute maintains identical physical dimensions and lead spacing for direct board compatibility.
