ICL161D13MIC

Inrush Current Limiters (ICL) Overview

The ICL161D13MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton Electronics ICL series, functioning as an inrush current limiter. It features a nominal resistance of 16 Ohms with a tolerance of ±20%. The component has a B-parameter of 2900 K and is rated for a steady-state current of 3 Amperes. Its physical dimensions are specified as 13.00 mm (0.512 inches) in length. The device utilizes leaded construction and is supplied in bulk packaging.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences to protect downstream circuitry.
• Exhibits negative temperature coefficient characteristics where resistance decreases significantly as operating temperature rises.
• Features robust leaded construction designed for through-hole mounting applications.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Motor drive inputs

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value against the manufacturer datasheet, as variations exist within the ICL family. Confirm that the 16 Ohm resistance and 3 Ampere current rating align with the thermal requirements of the target application. Ensure the 13 mm package size fits the designated PCB footprint and clearance constraints before finalizing procurement.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 16 Ohm initial resistance is required to limit peak charging currents. The 3 Ampere steady-state rating must exceed the maximum continuous load current of the circuit. Verify that the 2900 K Beta value provides the necessary sensitivity for the specific temperature range of the application environment.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors specifically engineered for inrush current limiting. These components are distinct from standard temperature sensing thermistors by their ability to handle high energy pulses during startup while maintaining low resistance during normal operation.

Inrush Current Limiters (ICL) Replacement Considerations

Compatible substitutes include other ICL series parts with matching 16 Ohm resistance and similar current ratings, such as ICL161D18MIC or ICL161D15MIC, provided the physical dimensions and thermal characteristics meet the design requirements.
