ICL150D09MIB

Inrush Current Limiters (ICL) Overview

The Eaton ICL150D09MIB is a Negative Temperature Coefficient (NTC) thermistor belonging to the ICL series, designed for inrush current limiting applications. It features a nominal resistance of 1.5 Ohms at standard reference conditions and utilizes an 'I lead' configuration with a body diameter of 9 mm. The component exhibits a Beta value of 2500 K and adheres to B1 beta definition standards. Resistance tolerance is specified as ±20%, while beta tolerance falls under category J. The device is supplied in bulk packaging and complies with RoHS directives, ensuring suitability for environmentally conscious electronic assemblies requiring reliable thermal protection.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter by providing high initial resistance that decreases as temperature rises during operation
• Utilizes NTC material properties to manage transient energy spikes in power circuits
• Constructed with I leads for secure mechanical mounting and electrical connection

Inrush Current Limiters (ICL) Applications

• Power supply input stages for surge current suppression
• Transformer primary circuit protection
• Motor drive inrush management

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix MIB against the manufacturer's latest datasheet to confirm lead type and tolerance class. Ensure the 1.5 Ohm resistance and 9 mm diameter align with the target circuit's thermal and electrical requirements. Confirm RoHS compliance status through official documentation prior to integration into regulated products.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 1.5 Ohm baseline resistance and 9 mm form factor are required for inrush control. Evaluate the 2500 K Beta constant against the expected operating temperature range to ensure accurate thermal response. Consider the ±20% resistance tolerance for circuit design margins and verify compatibility with the I lead termination style for PCB or chassis mounting.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL family of NTC thermistors, specialized for circuit protection. It shares the series characteristics of rapid resistance drop upon heating but differs from other models in its specific 1.5 Ohm resistance and 9 mm physical dimensions. The designation distinguishes it from variants with different lead types, diameters, or beta values within the broader product line.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with Eaton ICL150D11MIB if a larger 11 mm diameter is acceptable. Verify equivalent 1.5 Ohm resistance and similar Beta constants in alternative brands before substitution.
