Abstract
A composite electronic component includes a main body including insulating layers, first and second input terminals, first and second output terminals, a ground terminal, first and second filters, and a resistance pattern connected between the second filter and the ground terminal. The first filter includes a first coil pattern connected between the first input terminal and the first output terminal, and a second coil pattern connected between the second input terminal and the second output terminal. The first and second coil patterns form a common mode filter. The second filter includes a third coil pattern connected between the first input terminal and the ground terminal, and a fourth coil pattern connected between the second input terminal and the ground terminal. The third and fourth coil pattern form a differential mode filter. The resistance pattern is on the insulating layer different from those of the first to fourth coil patterns.
