An EMI filter is described. The filter includes an input, an output, first and second line-side X capacitors, and a line-side Y capacitor. The input includes first and second input terminals. The output includes first and second output terminals. A first conductive path is defined between the first input terminal and the first output terminal. A second conductive path is defined between the second input terminal and the second output terminal. The first line-side X capacitor is coupled between the first conductive path and the second conductive path, and the second line-side X capacitor is coupled between the first conductive path and the second conductive path in series with the first line-side X capacitor. The second line-side X capacitor is coupled to the first line-side X capacitor at a common point. A first end of the line-side Y capacitor is coupled to the common point.
