ICL101D20MIC

Inrush Current Limiters (ICL) Overview

The ICL101D20MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton Electronics ICL series, designed for inrush current limiting applications. It features a nominal resistance of 10 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 7 Amperes and has a physical diameter of 23.00 mm (0.906 inches). It utilizes a B-parameter of 3150 K for temperature-resistance characterization and adheres to the B1 beta definition. The device is packaged in bulk and complies with RoHS standards.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up phases to protect downstream circuitry.
• Features a robust 23.00 mm body size suitable for high-current industrial environments.
• Utilizes NTC characteristics to automatically reduce resistance as temperature increases.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Motor drive systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific package type and lead configuration against the official Eaton datasheet before integration. Confirm that the 7 A steady-state current rating aligns with the thermal management requirements of the target application. Ensure compatibility with the 10 Ohm nominal resistance value for the intended inrush limiting calculation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm initial resistance and 7 A continuous current capacity are required. The 23.00 mm diameter indicates suitability for higher energy absorption compared to smaller packages. Consider the 3150 K beta value for accurate temperature modeling in the specific operating range.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors. These components are specialized for circuit protection rather than general sensing. The 'D20' designation typically refers to the dimensional class within the series, ensuring mechanical interchangeability with other parts in the same size category.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 10 Ohm resistance, 7 A current rating, and 23.00 mm diameter. Verify that alternative manufacturers provide equivalent B-parameter values and thermal characteristics to maintain circuit performance.
