An integral dual frequency by-pass device is of one or more ceramic dielectric layers, the opposed surfaces of which are formed with electrodes of generally U-shaped configuration. The base portions of the electrodes are exposed at opposite surfaces of the monolith, the leg portions of the U-shaped electrodes extending toward the base portions of electrodes of opposite polarity. The overlap or registration area of one pair of legs differs from the overlap area of the other leg pair with the result that two capacitors of different values are formed, the capacitors being in parallel and accordingly defining low impedance path at two discrete frequencies. By varying the conductive paths as a function of the length of the electrode and/or the base of the U, a desired internal inductance is be developed.
An integrated ceramic dual frequency by-pass device including a parallel connected pair of ceramic capacitors of disparate values, each capacitor including a series connected inductance comprising at least one planar dielectric layer, a first electrode and a second electrode disposed on respective opposite surfaces of said dielectric layer, said first electrode and said second electrode each being of generally U-shape and including a base portion and a pair of leg portions extending from said base portion, said base portion of said first electrode being disposed at an opposite end of said dielectric layer from said base portion of said second electrode, said leg portions of each of said first electrode and said second electrode extending toward said base portion of the other, each of said leg portions of said first electrode being disposed in registry with an area of respective said leg portions of said second electrode, the areas of registration being of different values whereby a capacitance defined between a first registering pair of said leg portions differs from a capacitance defined between a second registering pair of said leg portions.
