ICL500D20MIC

Inrush Current Limiters (ICL) Overview

The ICL500D20MIC is a negative temperature coefficient (NTC) thermistor from the Eaton ICL series, designed for inrush current limiting. It features a nominal resistance of 5 Ohms at standard reference conditions and utilizes a Beta value of 3000 K with J tolerance. The component measures 20 mm in size with leaded termination and is supplied in bulk packaging.

Inrush Current Limiters (ICL) Feature Summary

• Provides effective inrush current limitation during power-up sequences
• Utilizes NTC characteristics to reduce steady-state resistance after activation
• Leaded construction facilitates through-hole mounting on circuit boards

Inrush Current Limiters (ICL) Applications

• Power supply input stages
• Transformer primary circuits
• Capacitor charging protection

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific Beta constant and tolerance requirements against the target application datasheet. Confirm that the 20 mm physical dimensions fit the designated PCB footprint. Ensure the rated current capacity meets the peak inrush demands of the load circuit without thermal damage.

Inrush Current Limiters (ICL) Selection Notes

Select this part when a 5 Ohm initial resistance is required to limit startup currents. The 3000 K Beta value indicates specific temperature-resistance behavior suitable for general industrial power applications. Compare against other ICL family members if different resistance or size constraints exist.

Inrush Current Limiters (ICL) Part Context

This component belongs to the Eaton ICL series of inrush current limiters. These devices are engineered to protect sensitive electronic components from high initial currents. The D20 suffix denotes the 20 mm body size, while MIC indicates the specific lead and packaging configuration.

Inrush Current Limiters (ICL) Replacement Considerations

Substitutes within the same Eaton ICL family may offer different resistance values or physical sizes. Verify electrical compatibility before replacing. Cross-reference with other manufacturers' NTC inrush limiters only if pinout and thermal ratings match exactly.
