Abstract
Disclosed is a filter device comprising at least a shell, a first discoidal capacitor, a second discoidal capacitor, and an inductor. The shell is elongated in a stack direction. The first discoidal capacitor and the second discoidal capacitor are disposed within the shell, where the first discoidal capacitor is stacked above the second discoidal capacitor along the stack direction. The inductor comprises a first patterned conductive line disposed within the shell. The first patterned conductive line is coupled between the first discoidal capacitor and the second discoidal capacitor. The first patterned conductive line is wound in a winding direction traversing the stack direction.
