ICL400D11MIB

Inrush Current Limiters (ICL) Overview

The ICL400D11MIB is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL family, designed as an inrush current limiter. It features a nominal resistance of 4 Ohms with a tolerance of ±20% and a B-parameter of 2700 K. The component supports a steady-state current of 4.5 A and has a physical size of 11 mm (0.472 inches). It is supplied in bulk packaging.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting for electronic circuits
• Utilizes NTC material properties for thermal protection
• Designed for integration into switch mode power supplies

Inrush Current Limiters (ICL) Applications

• Switch mode power supplies (SMPS)
• Household electrical appliances
• White goods
• DC/DC converters

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value against the manufacturer datasheet, as sources indicate variations between 2500 K and 2700 K for this series. Confirm that the 4.5 A current rating aligns with the target circuit requirements. Ensure the 11 mm form factor fits the designated PCB layout or housing constraints before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low initial resistance of 4 Ohms is required to manage surge currents. The 4.5 A continuous current rating suits moderate power applications. Consider the 2700 K beta value for temperature compensation characteristics. Verify compatibility with the specific voltage ratings of the application environment.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors. These components are specialized for protecting sensitive electronics from high startup currents. The ICL400D11MIB variant specifically offers a 4 Ohm resistance profile within the standard 11 mm package size common to this product line.

Inrush Current Limiters (ICL) Replacement Considerations

Consult official Eaton documentation for direct cross-references. Generic NTC thermistors may not match the precise beta tolerance or mechanical dimensions required for reliable inrush limiting performance.
