ICL250D11MIB

Inrush Current Limiters (ICL) Overview

The ICL250D11MIB is a Negative Temperature Coefficient (NTC) thermistor from the Eaton ICL family, designed as an inrush current limiter. It features a nominal resistance of 2.5 Ohms at 25°C with a tolerance of ±20%. The component has a Beta value of 3300 K and utilizes lead wire configuration. Its physical dimensions include a diameter of 11 mm and a lead length of 12 mm. Rated for a steady-state current of 5.5 A, it operates within a bulk packaging format.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limiting to protect downstream electronic components during power-up sequences.
• Features negative temperature coefficient characteristics where resistance decreases significantly as temperature rises.
• Constructed with radial leaded terminals suitable for through-hole mounting on printed circuit boards.

Inrush Current Limiters (ICL) Applications

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

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific electrical parameters against the official Eaton datasheet before integration. Confirm that the 2.5 Ohm resistance and 5.5 A rating align with the target circuit requirements. Ensure the 11 mm diameter package fits the available PCB space. Check RoHS compliance status if required by project specifications.

Inrush Current Limiters (ICL) Selection Notes

Select this component when a low-resistance NTC thermistor is needed for high-current applications. The 2.5 Ohm value suits circuits requiring minimal voltage drop during normal operation. The 11 mm size offers a balance between thermal mass and physical footprint. Consider the 5.5 A steady-state rating to ensure safe operation under continuous load conditions without overheating.

Inrush Current Limiters (ICL) Part Context

This part belongs to the Eaton ICL series of inrush current limiters. These devices are specialized NTC thermistors engineered specifically for managing transient currents. The series offers various resistance values and physical sizes to accommodate different power levels and enclosure constraints across industrial and consumer electronics.

Inrush Current Limiters (ICL) Replacement Considerations

Direct substitutes must match the 2.5 Ohm resistance, 5.5 A rating, and 11 mm diameter. Verify Beta constant compatibility for accurate thermal modeling. Cross-reference pinout and lead spacing to ensure mechanical fitment on existing PCB layouts.
