ICL150D25MIC

Inrush Current Limiters (ICL) Overview

The ICL150D25MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton Electronics ICL series, designed as an inrush current limiter. It features a nominal resistance of 1.5 Ohms at 25°C with a tolerance of ±20%. The component has a steady-state current rating of 17 A and a Beta value of 2800 K. It utilizes leaded construction with a body diameter of 25 mm (1.0 inch). The device is supplied in bulk packaging and complies with RoHS standards.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits during power-up
• Utilizes NTC material properties for automatic resistance adjustment based on temperature
• Supports high steady-state current handling capabilities

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Capacitor charging control

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance code against the manufacturer datasheet prior to ordering. Confirm that the leaded package dimensions align with the target PCB layout requirements. Ensure the thermal management design accounts for the self-heating characteristics inherent to inrush current limiting applications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 1.5 Ohm initial resistance is required to limit peak inrush currents. The 17 A steady-state rating determines the maximum continuous load capacity. Consider the 25 mm diameter for spatial constraints and the 2800 K Beta value for temperature sensitivity matching within the system design.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of inrush current limiters. These components are specifically engineered to replace traditional resistors or fuses in applications requiring controlled current ramp-up. The ICL series offers various resistance and current ratings to suit different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Eaton ICL series parts with matching resistance and current ratings, such as ICL150D30MIC for larger diameter requirements. Cross-manufacturer replacements require careful verification of Beta values, steady-state current limits, and physical footprint compatibility.
