Abstract
The present invention reduces the volume and weight of capacitive and inductance devices, particularly used in filters, by combining the capacitive elements and inductive elements into the same construction. Accordingly, alternating conducting and dielectric sheets of material are wound into a coil. The conducting sheets can be variously connected to signal lines and to ground in order to form common mode, differential mode and/or mixed mode filters.
