AWCDMC-2019H-12

Overview

The AWCDMC-2019H-12 is a through-hole common mode choke from AW Coil, designed for power line filtering. It features an inductance of 12 mH at 10 kHz and supports a maximum current rating of 3A. The component has a maximum DC resistance (DCR) of 150mOhm and a rated AC voltage of 250V. It utilizes a horizontal package with four PC pins. The unit provides integrated common and differential mode filtering capabilities within a single compact form factor.

Feature Summary

• Integrates both common-mode and differential-mode filtering functions into a single power-line component.

Applications

• Power supply input filtering
• AC/DC converter noise suppression

Procurement Notes

Verify the specific suffix 'H' against official AW Coil documentation to confirm mechanical orientation and pin configuration. Ensure the 12 mH inductance value aligns with circuit requirements at the target frequency. Confirm that the 3A current rating and 150mOhm DCR meet system thermal and efficiency specifications before procurement.

Selection Notes

Select this component when combined common and differential mode attenuation is required on a single power line. The 12 mH inductance offers significant impedance at low frequencies. Verify that the through-hole mounting style and horizontal body dimensions fit the PCB layout constraints. Ensure the 250V AC rating exceeds the operating voltage of the application.

Part Context

This part belongs to the AWCDMC series, which combines common-mode chokes with differential-mode filters. The series is designed to simplify power line EMI suppression by replacing multiple discrete components with a single integrated unit. AW Coil manufactures these components using specialized winding techniques to achieve high performance in a compact footprint.

Replacement Considerations

AWCDMC-2019V-12 is a related variant in the same series. Verify if the leakage inductance and current range differences are acceptable for the specific application requirements.
