ICL680D25MIC

Inrush Current Limiters (ICL) Overview

The ICL680D25MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL family, designed for inrush current limiting. It features a nominal resistance of 6.8 Ohms with a tolerance of ±20%. The component supports a steady-state current of 10 A and utilizes an I-lead configuration. Its physical dimensions include a diameter of 25 mm and a length of 28.00 mm (1.102 inches). The Beta value is defined as B1, with a coefficient of 3150 K.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Utilizes NTC characteristics to reduce resistance as temperature increases
• Features robust I-lead construction for secure circuit mounting

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Motor drive inrush control

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant designation against project requirements, as documentation references both B1 definitions and a 3150 K coefficient. Confirm that the 10 A steady-state current rating aligns with the maximum operational load of the target application. Ensure the 25 mm package size fits within the designated thermal and spatial constraints of the assembly.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 6.8 Ohm initial resistance is required to limit peak charging currents. The 10 A rating suits moderate-power applications. Consider the 25 mm diameter for adequate heat dissipation. Verify compatibility with the system's voltage levels and the specific thermal environment where the thermistor will operate continuously after the initial surge phase.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors. These components are engineered specifically for protecting electronic equipment from high initial charging currents. The ICL680D25MIC variant offers a balance of low resistance and high current capacity, distinguishing it from higher-resistance or lower-current models within the same product line.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference other ICL series parts with similar 6.8 Ohm resistance and 10 A current ratings. Ensure substitute components match the 25 mm diameter and I-lead configuration to maintain mechanical fit and thermal performance without redesigning the PCB layout.
