ICM2020ER501RA

Common Mode Chokes Overview

The Vishay Dale ICM2020ER501RA is a surface-mount common mode choke designed for DC/DC power supply applications. It features an unshielded ferrite core within a 2020 (2.0mm x 2.0mm) package. Key electrical parameters include a nominal impedance of 500 Ohms with a tolerance of 50%, measured at 100 MHz. The component supports a maximum DC current rating of 4.5A and exhibits a maximum DC resistance of 10.5 mOhms. It operates reliably within a temperature range of -40°C to +125°C and holds AEC-Q200 automotive qualification.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for high-current DC/DC power lines
• Automotive-grade reliability certified under the AEC-Q200 standard
• Compact surface-mount footprint suitable for space-constrained PCB layouts

Common Mode Chokes Applications

• DC/DC Power Supplies
• Automotive electronic circuits
• Signal line filtering in harsh environments

Common Mode Chokes Procurement Notes

Verify the specific suffix 'RA' against official Vishay documentation to confirm reel packaging specifications, as distributor listings may vary. Ensure the selected variant matches the required 50% impedance tolerance and 4.5A current rating for your design. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for your application.

Common Mode Chokes Selection Notes

Select this component when designing for high-current DC/DC converters requiring robust noise attenuation in compact spaces. The 500 Ohm impedance offers significant filtering capability compared to lower-impedance alternatives. Consider the 4.5A current rating to ensure adequate headroom for peak load conditions without saturation. The wide operating temperature range supports deployment in demanding thermal environments.

Common Mode Chokes Part Context

This part belongs to the Vishay Dale ICM series of common mode chokes, which are engineered for signal integrity and power line protection. The ICM2020 variant specifically targets applications needing higher current handling than smaller packages like 0603 or 0805, while maintaining a small profile relative to larger through-hole or industrial-sized SMD chokes.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult Vishay's official cross-reference tools or datasheets for verified equivalents that match the 2020 package, 500 Ohm impedance, and 4.5A current rating specifications.
