ICL100D09MIB

Inrush Current Limiters (ICL) Overview

The ICL100D09MIB 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 Ohm with a tolerance of ±20% and a Beta parameter of 2500 K. The component has a physical size of 9 mm (0.374 inches) and utilizes lead-style packaging. It operates within a standard bulk package configuration.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting through high initial resistance that decreases with temperature rise
• Utilizes NTC characteristics for rapid thermal response during power-up events
• Designed for robust protection against transient current spikes in electronic circuits

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge protection
• Transformer primary winding protection
• Capacitor charging circuit current limiting

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and resistance tolerance against the official Eaton datasheet to ensure compatibility with system thermal requirements. Confirm that the 9 mm leaded form factor matches the target PCB layout constraints before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low nominal resistance of 1 Ohm is required for moderate current handling. The 2500 K Beta value indicates specific sensitivity characteristics suitable for general-purpose inrush limiting applications where precise thermal tracking is not the primary design constraint.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of inrush current limiters. These components are distinct from standard temperature sensing thermistors, as they are optimized for energy absorption and peak current suppression rather than linear temperature measurement across wide ranges.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 1 Ohm resistance, 9 mm diameter, and similar Beta constants. Verify that alternative parts support comparable steady-state current ratings without exceeding thermal limits in the application environment.
