ICL501D11MIB

Inrush Current Limiters (ICL) Overview

The ICL501D11MIB is an NTC thermistor from the Eaton Electronics ICL series, designed as an inrush current limiter. It features a nominal resistance of 50 ohms at standard reference temperature and utilizes leaded construction with an 11 mm body size. The component exhibits a Beta value (B) of 3200 K with J tolerance for beta consistency and B1 beta definition. Rated for a steady-state current of 2 A, it provides effective protection against high initial surge currents in electronic circuits.

Inrush Current Limiters (ICL) Feature Summary

• Functions as an inrush current limiter to protect sensitive electronic components during power-up
• Utilizes negative temperature coefficient characteristics to reduce resistance as temperature rises
• Features leaded construction suitable for through-hole mounting applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Motor drive circuits
• Transformer primary side protection

Inrush Current Limiters (ICL) Procurement Notes

Verify that the specific order matches the Eaton Electronics Division manufacturer designation and the full part number ICL501D11MIB. Confirm the 50-ohm resistance and 3200 K Beta parameter align with circuit design requirements. Ensure the 11 mm package dimension and lead configuration are compatible with the target PCB layout. Check RoHS compliance status if required by project specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a 50-ohm cold resistance is required for inrush limiting. The 3200 K Beta value indicates specific thermal response characteristics suitable for general-purpose power applications. The 2 A steady-state rating must exceed the maximum operating current of the protected load. Consider the 11 mm size constraint for mechanical integration within the enclosure or assembly.

Inrush Current Limiters (ICL) Part Context

This device belongs to the ICL family of NTC thermistors manufactured by Eaton Electronics. These components are specialized for managing startup surges rather than precise temperature sensing. The ICL series offers various resistance values and sizes to match different power levels and physical space constraints in industrial and commercial electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative NTC inrush limiters based on matching resistance, Beta value, and current ratings.
