ICL161D11MIB

Inrush Current Limiters (ICL) Overview

The ICL161D11MIB is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL family, designed for inrush current limiting applications. It features a nominal resistance of 16 Ohms at standard reference conditions and utilizes an I lead configuration with an 11 mm disc size. The component exhibits a Beta value of 2900 K with J beta tolerance and B1 beta definition. Rated for a continuous current of 2.5 A, this device provides reliable thermal management in electronic circuits by restricting initial surge currents during power-up phases.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance requirements against the official Eaton datasheet before procurement. Confirm that the 11 mm form factor and I lead style align with the target PCB layout constraints. Ensure the 2.5 A continuous current rating meets the operational demands of the intended application circuit without exceeding thermal limits.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 16 Ohm initial resistance is required to limit inrush current effectively. Consider the 2900 K Beta value for accurate thermal modeling within the specific circuit environment. Evaluate the 11 mm package size against available board space and verify compatibility with automated placement equipment if used in high-volume manufacturing environments.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors specifically engineered for inrush current suppression. The series offers various resistance values and physical sizes to accommodate different power levels and circuit requirements. The ICL161D11MIB represents a mid-range solution balancing resistance magnitude and current handling capacity for standard industrial and commercial electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference alternative NTC thermistors with identical 16 Ohm resistance, 2.5 A rating, and 11 mm dimensions. Verify that substitute parts match the 2900 K Beta constant and lead configuration to ensure equivalent performance in inrush limiting applications without redesigning the host circuit.
