Inrush Current Limiters (ICL) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct tolerance and lead configuration. Confirm that the 14 A steady-state current rating aligns with the thermal management requirements of the target application circuit. Cross-reference the 2.5 Ohm resistance value with system design specifications to guarantee proper inrush control performance.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low initial resistance of 2.5 Ohms is required to limit peak charging currents. Ensure the operating environment accommodates the thermal dissipation characteristics of the device. Verify compatibility with the 2900 K Beta constant for accurate temperature-resistance modeling in the specific application context.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors, which are specialized for protecting electronic equipment from high surge currents. The ICL series offers various resistance values and sizes to suit different power levels. This specific model represents a low-resistance variant suitable for higher current applications compared to standard sensing thermistors.

Inrush Current Limiters (ICL) Replacement Considerations

Consult Eaton Electronics documentation for direct cross-references. Equivalent components must match the 2.5 Ohm resistance, 14 A current rating, and similar Beta constants to maintain circuit integrity without redesign.
