Abstract
Disclosed is a multilayered common mode filter exhibiting wideband characteristics as well as allowing uniform resistance and inductance in the coil patterns that form the channels. The disclosed multilayered common mode filter includes first and second capacitor layers on top and bottom, respectively, of an electrode stack, to overlap with multiple coil patterns and form additional capacitance, the electrode stack including stacked upper and lower electrode layers each having a stacked body provided with multiple coil patterns.
Claims18
A multilayered common mode filter comprising:
- an upper electrode layer configured as a stacked body including a first coil pattern, a second coil pattern, and a third coil pattern;
- a lower electrode layer configured as a stacked body including a fourth coil pattern, a fifth coil pattern, and a sixth coil pattern and arranged on a bottom of the upper electrode layer;
- a first capacitor layer configured as a stacked body including a capacitor pattern and a ground pattern, arranged on a top of the upper electrode layer, and configured to overlap the first coil pattern to the sixth coil pattern to form an additional capacitance;
- and
- a second capacitor layer configured as a stacked body including a capacitor pattern and a ground pattern, arranged on a bottom of the lower electrode layer, and configured to overlap the first coil pattern to the sixth coil pattern to form an additional capacitance.
