ICL100D20MIC

Inrush Current Limiters (ICL) Overview

The ICL100D20MIC is a radial lead negative temperature coefficient (NTC) thermistor from the Eaton ICL series, designed as an inrush current limiter. It features a nominal resistance of 1 Ohm with a tolerance of ±20% and supports a maximum steady-state current of 16 A. The component has a cylindrical body diameter of 0.906 inches (23.00 mm) and utilizes a bulk packaging format. It is RoHS3 compliant and classified under circuit protection components for managing electrical surge loads.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect downstream circuits from high initial current spikes during power-up events.
• Utilizes NTC material properties where resistance decreases significantly as temperature rises, allowing normal operating current flow after the initial transient phase.

Inrush Current Limiters (ICL) Applications

• Protection of power supply inputs against inrush current surges
• Circuit protection in electronic equipment requiring surge current management
• General circuit protection applications within industrial or commercial electronics

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific steady-state current rating and physical dimensions against the official Eaton datasheet prior to integration. Confirm that the 16 A rating aligns with the application's thermal requirements. Ensure compliance with RoHS3 standards if required by the end-product specifications. Cross-reference the part number suffix to confirm the exact lead spacing and package variant matches the design constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 1 Ohm resistance at 25°C is required for inrush limiting. Consider the 16 A steady-state current capacity and the 23.00 mm body size for mechanical fit. Evaluate the thermal dissipation characteristics relative to the ambient environment. Compare with other ICL family members if different resistance values or current ratings are needed for alternative circuit designs.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors specifically engineered for inrush current limitation. These components are distinct from standard sensing thermistors, focusing on energy absorption and thermal stability during high-current transients. The ICL series provides a reliable solution for protecting sensitive electronic components from damage caused by sudden power application.

Inrush Current Limiters (ICL) Replacement Considerations

Consult the Eaton ICL family datasheet for cross-referenced parts with similar resistance and current ratings. Verify that any substitute component matches the 1 Ohm nominal resistance, 16 A steady-state current, and 23.00 mm diameter specifications. Ensure the replacement maintains the same radial lead configuration and RoHS3 compliance status.
