ICL101D15MIC

Inrush Current Limiters (ICL) Overview

The ICL101D15MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL series, functioning as an inrush current limiter. It features a nominal resistance of 10 Ohms at standard reference conditions and utilizes a Beta value of 2950 K for temperature-resistance characterization. The component has a physical size of 15 mm and employs I-type leads for mounting. It supports a steady-state current of 5 A and includes a B1 beta definition specification.

Inrush Current Limiters (ICL) Feature Summary

• Provides circuit protection by limiting initial current surges during power-up
• Utilizes NTC characteristics to reduce resistance as temperature increases
• Designed with I-type leads for secure mechanical attachment

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant (2950 K) and tolerance class against the official Eaton datasheet for the exact revision. Confirm lead type and physical dimensions match the design requirements. Ensure the 5 A steady-state current rating exceeds the application's maximum operating current under all thermal conditions.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 10 Ohm cold resistance and 5 A current handling capability. The 15 mm size and I-type leads dictate the board layout constraints. Verify that the 2950 K Beta value aligns with the system's thermal management calculations and inrush duration requirements.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of inrush current limiters. These components are specialized NTC thermistors designed specifically for surge suppression rather than general temperature sensing. The ICL series offers various resistance and current ratings to suit different power levels.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other Eaton ICL parts sharing the 10 Ohm resistance and 5 A rating. Verify that any substitute maintains the same 2950 K Beta value and 15 mm form factor to ensure compatibility with existing PCB footprints and thermal profiles.
