ICL300D11MIB

Inrush Current Limiters (ICL) Overview

The ICL300D11MIB is an NTC thermistor from the Eaton ICL family, designed as an inrush current limiter. It features a nominal resistance of 3 Ohms with a ±20% tolerance and a B parameter of 2650 K. The component utilizes I-lead configuration and has a body size of 11 mm (0.472 inches). It supports a steady-state current of 5.5 A and is packaged in bulk quantities.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect electronic circuits during power-up
• Utilizes negative temperature coefficient characteristics for automatic resistance adjustment
• Features I-lead configuration for through-hole mounting applications

Inrush Current Limiters (ICL) Applications

• Household electrical appliances
• White goods
• Switch mode power supplies (SMPS)
• DC/DC converters

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value against the official datasheet, as sources indicate variations between 2650 K and 2500 K for similar series parts. Confirm the lead type and physical dimensions match the design requirements. Ensure compliance with RoHS standards if required by the target application environment.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low-resistance inrush limiter is required for moderate current applications up to 5.5 A. The 3 Ohm nominal value suits circuits needing minimal voltage drop during normal operation. Consider the 11 mm body size for adequate heat dissipation and mechanical stability in the assembly layout.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors specifically engineered for inrush current limiting. The series offers various resistance values and beta constants to accommodate different circuit designs. The ICL300D11MIB represents a mid-range option within the family, balancing resistance and current handling capabilities.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Eaton ICL series parts with matching 3 Ohm resistance and similar current ratings. Verify that alternative components maintain the same I-lead configuration and 11 mm form factor to ensure compatibility with existing PCB footprints and thermal management strategies.
