ICL500D13MIC

Inrush Current Limiters (ICL) Overview

The ICL500D13MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton Electronics ICL family, designed for inrush current limiting. It features a nominal resistance of 5 Ohms at standard reference conditions and utilizes leaded construction with a 13 mm body size. The component exhibits a Beta value of 2750 K with B1 beta definition and J tolerance class. Rated for a steady-state current of 5 A, it serves as a critical protection element in power supply circuits to manage initial surge currents.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance requirements against the target application datasheet. Confirm that the 5 A steady-state current rating aligns with the operational load. Ensure the 13 mm physical dimensions fit within the designated PCB footprint and clearance constraints. Cross-reference the manufacturer's latest documentation for any updates to the ICL series specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 5 Ohm initial resistance is required to limit peak inrush current in low-to-medium power circuits. The 13 mm size offers a balance between thermal mass and spatial efficiency. Consider the 2750 K Beta value for temperature-resistance curve calculations. Ensure the operating environment does not exceed the maximum allowable surface temperature limits defined in the official Eaton datasheet.

Inrush Current Limiters (ICL) Part Context
