Abstract
Incrementally adjustable multilayer monolithic capacitors having a set of base electrodes extending to and being coextensive with a first terminal end surface of the capacitor and a set of incremental electrodes extending to and being coextensive with a side surface of the capacitor. The base electrodes are electrically interconnected by a conductive metal coating on the first terminal end surface. Capacitance values of the resultant capacitor can be incrementally adjusted by electrically interconnecting or disconnecting one or more of the incremental electrodes either along the side surface to which they extend and are coextensive with or along the second terminal end surface of the capacitor.
Claims15
A multilayer monolithic ceramic capacitor comprising a dielectric material body having two major surfaces, a first side surface, a second side surface, a first end terminal and a second end terminal;
- at least two base electrodes each of which is in a plane substantially parallel to the major surfaces and each of which extends to and is coextensive with only the first end terminal there being no base electrodes extending to and in direct contact with the second end terminal;
- a conductive coating on the first end terminal which electrically interconnects each of the base electrodes extending to and coextensive with the first end terminal;
- and, at least one incremental electrode which extends, in a plane substantially parallel to the major surfaces, to, and is coextensive with, at least one side surface of the capacitor.
