ICL300D05MIB

Inrush Current Limiters (ICL) Overview

The Eaton ICL300D05MIB is a Negative Temperature Coefficient (NTC) thermistor from the ICL series, designed for inrush current limiting applications. It features a nominal resistance of 3 Ohms at standard reference conditions and utilizes a Beta value of 2500 K for temperature-resistance characterization. The component is rated for a steady-state current of 2 Amperes and has a physical body diameter of 7.00 mm (0.276 inches). It employs lead-style termination with a 5 mm lead length configuration. The device exhibits a Beta tolerance of J and adheres to B1 Beta definition standards, packaged in bulk quantities.

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta value and tolerance code against the manufacturer's official datasheet prior to procurement, as variations may exist between documentation sources. Confirm that the 2 A steady-state current rating aligns with the thermal requirements of the target application circuit. Ensure the 7 mm body size fits within the designated PCB footprint or enclosure constraints. Cross-reference the lead style and length specifications to guarantee compatibility with assembly processes.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low resistance value of 3 Ohms is required for moderate current handling up to 2 Amperes. The 2500 K Beta constant suits applications requiring specific temperature compensation curves typical of general-purpose power electronics. Consider the 7 mm diameter for available board space. Evaluate the thermal dissipation capabilities relative to the ambient operating environment to ensure reliable long-term performance without overheating during continuous operation cycles.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors, which are specialized for managing high initial currents in electronic systems. The ICL series offers various resistance values and physical sizes to accommodate different power levels. This specific model represents a mid-range option within the lineup, balancing low resistance with moderate current capacity for standard industrial and commercial power applications.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes include other Eaton ICL series parts with matching 3 Ohm resistance and similar current ratings, such as variants with different lead lengths or diameters if mechanical constraints allow. Verify that any replacement maintains the 2500 K Beta characteristic and 2 A current rating to ensure equivalent circuit behavior.
