ICL700D09MIB

Inrush Current Limiters (ICL) Overview

The ICL700D09MIB 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 7 Ohms at standard reference conditions and a B-parameter of 3100 K with J tolerance. The component has a physical size of 9 mm and utilizes leaded construction. Rated for a steady-state current of 3 A, it operates within a bulk packaging format. This device provides surge protection by limiting initial current spikes during circuit power-up.

Inrush Current Limiters (ICL) Feature Summary

• Limits electrical surge current upon initial circuit power application
• Negative temperature coefficient characteristic enables self-regulating resistance reduction
• Leaded construction facilitates through-hole mounting on printed circuit boards

Inrush Current Limiters (ICL) Applications

• Household electrical appliances
• White goods
• Switch mode power supplies (SMPS)
• DC/DC converters

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific datasheet version for the ICL700D09MIB to confirm thermal characteristics and derating curves. Ensure the selected component matches the required 7 Ohm resistance and 3 A current rating for the target application. Cross-reference the 9 mm body size against mechanical constraints in the design. Confirm compliance with relevant safety standards before integration.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 7 Ohm initial resistance is required to limit inrush current in low-power circuits. The 3 A rating suits applications with moderate peak loads. Consider the 3100 K B-parameter for temperature sensitivity requirements. Verify that the 9 mm form factor fits the available board space. Compare against higher resistance variants if lower surge currents are needed.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors specifically engineered for inrush current limiting. These components are distinct from general-purpose temperature sensing thermistors due to their high current handling capabilities and specific beta values optimized for surge suppression. The series offers various resistance and size options to match different power supply designs.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Eaton ICL series parts with similar 7 Ohm resistance and 3 A ratings, such as ICL700D20MIC or ICL700D30MIC, provided the physical size and lead configuration are compatible. Verify that alternative manufacturers' equivalents meet the same B-parameter and current specifications.
