Abstract: A filter component is adapted to an electrical system having first and second electric apparatuses. The filter component has a resistive element and first, second, third and fourth windings. The first electric apparatus has a power terminal being a first power terminal and another power terminal being a second power terminal. The second electric apparatus has a power terminal being a third power terminal and another power terminal being a fourth power terminal. The first and second windings are connected in series, and the third and fourth windings are connected in series. The first and third windings form a common-mode inductor suppressing a common-mode noise current. The first to fourth windings form a differential-mode inductor suppressing a differential-mode noise current. The resistive element is connected in parallel across at least one of the first to fourth windings.
