ICL101D09MIB

Inrush Current Limiters (ICL) Overview

The ICL101D09MIB is a Negative Temperature Coefficient (NTC) thermistor from the Eaton Electronics ICL series, designed for inrush current limiting applications. It features a nominal resistance of 10 Ohms at standard reference conditions and utilizes a B-parameter of 2750 K for temperature characterization. The component has a physical size of 9 mm with leaded termination. It supports a steady-state current rating of 2.5 A and offers a beta tolerance of J. The device is supplied in bulk packaging and complies with RoHS standards.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Features negative temperature coefficient characteristics for self-regulating resistance
• Utilizes leaded construction for through-hole mounting compatibility

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor control circuits
• Transformer protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific B-parameter value and tolerance code against the manufacturer datasheet prior to ordering. Confirm that the 2.5 A steady-state current rating meets the application requirements. Ensure the 9 mm package dimensions fit within the designated PCB footprint. Check compliance documentation for regional regulatory adherence.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 10 Ohm initial resistance is required for inrush limiting. Consider the 2750 K B-parameter for thermal modeling accuracy. Evaluate the 2.5 A current capacity against peak load demands. Verify the leaded package style matches the assembly process. Compare alternative ICL family variants if different resistance or size constraints exist.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of NTC thermistors specifically engineered for inrush current suppression. These components are distinct from general-purpose sensing thermistors by their ability to handle high initial surge currents while providing significant resistance at room temperature. The series offers various resistance values and sizes to suit diverse power electronics designs.

Inrush Current Limiters (ICL) Replacement Considerations

Consult Eaton official substitution guides for direct equivalents. Verify electrical parameters including resistance, B-value, and current ratings match exactly. Ensure mechanical dimensions and lead configurations are compatible with existing board layouts.
