ICL150D20MIC

Inrush Current Limiters (ICL) Overview

The ICL150D20MIC is a negative temperature coefficient (NTC) inrush current limiter from the Eaton ICL series. It features a nominal resistance of 1.5 Ohms at 25°C with a tolerance of ±20%. The component supports a maximum steady-state current of 14 A and has a body diameter of 23.00 mm (0.906 inches). It utilizes lead spacing of 7.50 mm (0.295 inches) and operates within the standard ICL family specifications for circuit protection.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limiting of high inrush currents during power-up sequences to protect downstream components.
• Features self-resetting capability, automatically returning to low resistance state after thermal dissipation.
• Constructed with robust epoxy encapsulation for mechanical stability and environmental resistance.

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitive load protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix codes against the official Eaton datasheet to confirm exact Beta constant and tolerance ratings. Ensure the selected variant matches the required steady-state current and physical dimensions for the target PCB layout. Cross-reference the manufacturer part number directly with the latest product documentation to avoid substitution errors.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required 1.5 Ohm initial resistance and 14 A continuous current rating. Evaluate the thermal energy absorption capabilities relative to the specific application's surge profile. Confirm that the 23 mm diameter and 7.5 mm lead spacing fit within the available board space and mounting constraints.

Inrush Current Limiters (ICL) Part Context

This device belongs to the Eaton ICL series of NTC thermistors designed specifically for inrush current limitation. These components are widely used in electronic equipment to mitigate the stress caused by charging large filter capacitors upon initial power application, ensuring reliable system startup.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other ICL series variants with matching electrical parameters such as ICL100D20MIC or ICL200D20MIC, provided the resistance and current ratings align with the design requirements. Always verify compatibility through official cross-reference lists.
