ICL600D18MIC

Inrush Current Limiters (ICL) Overview

The ICL600D18MIC is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL series, designed as an inrush current limiter. It features a nominal resistance of 6 Ohms with a tolerance of ±20% at 25°C. The component supports a maximum steady-state current of 7 Amperes and has a body diameter of 19.00 mm (0.748 inches). It utilizes a B-parameter of 2900 K for thermal characterization and includes lead spacing of 7.50 mm.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting through negative temperature coefficient characteristics
• Constructed with leaded design for through-hole mounting applications
• Engineered to withstand high initial surge currents while stabilizing circuit operation

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer protection circuits
• Capacitive load switching systems

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific electrical parameters against the official Eaton Electronics datasheet prior to integration. Confirm that the 6 Ohm resistance and 7 Ampere steady-state current ratings align with the target circuit requirements. Ensure the 19 mm package dimensions fit the designated PCB layout constraints. Validate compliance with relevant environmental standards such as RoHS3 before final procurement authorization.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 6 Ohm cold resistance is required to limit initial charging currents. The 7 Ampere rating suits moderate power applications where thermal management is feasible. Consider the 2900 K beta value for temperature compensation calculations. Evaluate the 19 mm form factor against available board space. Compare against other ICL family members if higher or lower current handling is necessary.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors specifically marketed as inrush current limiters. These components are distinct from standard temperature sensing thermistors by their ability to handle significant transient energy. The ICL series provides reliable protection for electronic equipment against damaging startup currents common in capacitive loads.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other Eaton ICL models offering similar 6 Ohm resistance values but different current ratings, such as the ICL600D20MIC which supports higher steady-state current. Verify that substitute parts maintain compatible physical dimensions and lead spacing for direct replacement without PCB modification.
