Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific ordering suffix matches the required physical dimensions and electrical ratings for your assembly. Confirm compliance with RoHS directives if environmental regulations apply to your manufacturing process. Ensure the selected package type aligns with your automated or manual placement equipment capabilities before finalizing orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 16 Ohm initial resistance is required to manage startup surge currents effectively. The 5 A steady-state rating must exceed the operational load current to prevent thermal failure. Verify that the 3200 K B-parameter suits the thermal environment and switching frequency requirements of the target application design.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors specifically engineered for inrush current limiting. These components are widely utilized in electronic power conversion systems where controlling initial charging currents is critical for component longevity and system stability.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other ICL series parts having similar 16 Ohm resistance and 5 A current ratings. Verify mechanical footprint compatibility and thermal dissipation characteristics before substituting with alternative manufacturers' offerings.
