ICL680D30MIC

Inrush Current Limiters (ICL) Overview

The ICL680D30MIC is an NTC thermistor from the Eaton ICL series, designed as an inrush current limiter. It features a nominal resistance of 6.8 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 12 A and has a physical diameter of 34.00 mm (1.339 inches) with a lead spacing of 7.50 mm (0.295 inches). It utilizes a B-parameter of 3200 K and adheres to the B1 beta definition.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter using negative temperature coefficient technology
• Provides high steady-state current handling capability for power protection
• Features standardized lead spacing for easy integration into circuit boards

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer inrush current suppression
• Capacitor charging circuit protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value and beta definition against the manufacturer's official datasheet, as variations exist within the ICL family. Confirm that the 34mm diameter and 7.50mm lead spacing match the target PCB layout requirements. Ensure the 12A steady-state current rating exceeds the application's operational limits to prevent thermal failure during continuous operation.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 6.8 Ohm initial resistance is required to limit peak charging currents effectively. The 12A steady-state rating makes it suitable for medium-power applications where standard limiters may overheat. Consider the 34mm body size for adequate heat dissipation and mechanical stability in high-current environments compared to smaller form factors.
