ICL131D11MIB

Inrush Current Limiters (ICL) Overview

The ICL131D11MIB is an NTC thermistor from the Eaton Electronics ICL family, designed as an inrush current limiter. It features a nominal resistance of 13 Ohms at standard reference temperature and a B-parameter of 2850 K with J tolerance. The component utilizes leaded construction with a 11 mm body size and is rated for a steady-state current of 3 A. Packaged in bulk, it serves as a critical protection element against high initial surge currents in electronic circuits.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective limitation of high inrush currents during power-up sequences
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature rises
• Features robust leaded construction suitable for through-hole mounting applications

Inrush Current Limiters (ICL) Applications

• Switch mode power supplies (SMPS)
• Motor starters
• Industrial control circuits
• Household electrical appliances

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific B-parameter of 2850 K matches the thermal design requirements. Confirm the 13 Ohm resistance value aligns with the circuit's impedance needs. Ensure the 3 A current rating exceeds the maximum expected operating current. Check that the 11 mm physical dimensions fit within the available board space constraints.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 13 Ohm initial resistance is required to limit surge current effectively. The 2850 K B-parameter indicates specific thermal sensitivity compared to other series variants. Consider the 3 A steady-state rating to ensure safe operation under continuous load conditions without overheating or degradation of performance over time.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of inrush current limiters. It shares the 11 mm form factor with other members like ICL102D11MIB but differs significantly in resistance and beta values. The ICL designation specifically denotes its function as a current limiter rather than a general-purpose sensing thermistor.

Inrush Current Limiters (ICL) Replacement Considerations

Substitutes must match the 13 Ohm resistance and 3 A current rating. Verify compatibility of the 2850 K B-parameter with existing thermal compensation networks. Physical footprint compatibility is ensured by the shared 11 mm size across the ICL family.
