ICM2020ER102RA

Common Mode Chokes Overview

The ICM2020ER102RA is a surface-mount common mode choke from the Vishay / Dale ICM2020-A series. It features a ferrite core and unshielded construction with standard SMD terminations. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz, with a tolerance of 30%. It supports a maximum DC current rating of 3 A and has a maximum DC resistance of 0.02 Ohms. The device operates within a temperature range of -40°C to +125°C and is designed for PCB mounting in compact applications.

Common Mode Chokes Feature Summary

• High current handling capability up to 3 A
• Low DC resistance of 0.02 Ohms
• Ferrite core construction for effective noise suppression

Common Mode Chokes Applications

• DC/DC Power Supplies

Common Mode Chokes Procurement Notes

Verify the specific suffix 'RA' against official Vishay documentation to confirm terminal configuration or tape/reel specifications. Ensure the selected variant matches the required impedance tolerance and current ratings for the target circuit design before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component for circuits requiring high current capacity and low insertion loss. The 1 kOhms impedance at 100 MHz makes it suitable for suppressing high-frequency noise in power supply lines while maintaining efficient DC conduction due to its minimal DC resistance.

Common Mode Chokes Part Context

This part belongs to the ICM2020-A series of common mode chokes manufactured by Vishay / Dale. The series is characterized by its robust ferrite core design and suitability for surface-mount technology, providing reliable electromagnetic interference filtering in space-constrained electronic assemblies.

Common Mode Chokes Replacement Considerations

Consult official Vishay databases for direct cross-references. Verify that any substitute maintains the 3 A current rating, 0.02 Ohms DC resistance, and 1 kOhms impedance at 100 MHz to ensure functional equivalence.
