ICL400D07MIB

Inrush Current Limiters (ICL) Overview

The ICL400D07MIB is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL family, designed as an inrush current limiter. It features a nominal resistance of 4 Ohms with a tolerance of ±20%. The component supports a maximum steady-state current of 3 A and utilizes leaded construction with a body diameter of 7 mm (0.335 inches). Key thermal characteristics include a Beta value of 2600 K, J tolerance for Beta parameters, and B1 beta definition.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective suppression of high initial surge currents during power-up sequences
• Utilizes negative temperature coefficient properties to automatically reduce resistance as operating temperature increases
• Features robust leaded construction suitable for through-hole mounting applications

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitive load protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure correct Beta tolerance and dimensional specifications. Confirm that the 3 A current rating aligns with the system's steady-state operational requirements. Check RoHS compliance status directly on the official product page or documentation before finalizing procurement orders.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low nominal resistance of 4 Ohms is required to minimize voltage drop during normal operation. Ensure the 3 A current capacity exceeds the circuit's maximum continuous load. Consider the 7 mm package size for adequate thermal dissipation and mechanical stability within the target enclosure design constraints.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of inrush current limiters. These components are specifically engineered to protect electronic equipment from damage caused by excessive charging currents. The ICL family offers various resistance and current ratings to match different power levels and form factors.

Inrush Current Limiters (ICL) Replacement Considerations

Cross-reference with other ICL series parts having similar 4 Ohm resistance and 3 A current ratings. Verify physical dimensions and lead spacing compatibility before substitution.
