AWCDMC-2019V-12

Overview

The AWCDMC-2019V-12 is an integrated common-mode and differential-mode filter manufactured by AW Coil. It features a vertical through-hole mounting configuration with flat wire construction. The component provides a minimum winding inductance of 12 mH at 10 kHz and a leakage inductance of 300 µH. It supports a rated current range of 2.5 to 3.0 A and operates within a temperature range of -40°C to 115°C. The unit has a voltage rating of 250 V AC and measures 25.00 mm x 15.00 mm.

Feature Summary

• Integrates common-mode and differential-mode filtering capabilities into a single two-winding power-line filter structure.
• Utilizes flat wire technology to achieve low-profile design suitable for high-density applications.
• Offers vertical through-hole mounting orientation for specific board layout requirements.

Applications

• Power line filtering in data center infrastructure
• EMI suppression for GPU VRM and accelerator power delivery systems
• High-density power conversion circuits requiring combined mode noise reduction

Procurement Notes

Verify the exact inductance tolerance and DC resistance values against the official manufacturer datasheet before integration. Confirm that the vertical footprint dimensions align with the PCB silkscreen and copper pad layout. Ensure the operating temperature range meets the thermal requirements of the final enclosure environment. Check for any specific handling instructions regarding the flat wire construction during assembly.

Selection Notes

Select this component when simultaneous common-mode and differential-mode attenuation is required in a compact form factor. The vertical orientation suits boards with limited surface area but available height clearance. Consider the 12 mH inductance level for lower frequency noise suppression compared to standard chokes. Evaluate the 3.0 A current rating against peak load conditions to prevent saturation.

Part Context

This part belongs to the AWCDMC series, which combines common-mode and differential-mode inductance in horizontal and vertical layouts. The series targets advanced power magnetics applications, including AI servers and high-performance computing hardware. AW Coil specializes in low-profile, ultra-low-DCR magnetics for GPU and accelerator power delivery systems.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Verify compatibility based on inductance, current rating, and physical footprint if cross-referencing with other integrated CMC/DMC filters from different manufacturers.

FAQ
