MUTILAYERED CHIP CAPACITOR AND CAPACITANCE TUNNING METHOD OF THE SAME

摘要

A multilayer chip capacitor and a method for controlling an electrostatic capacity thereof are provided to select a desired electrostatic capacity by connecting an external electrode to a power line without a separate multilayer chip capacitor. A multilayer chip capacitor(10) includes a main body(11), a plurality of first internal electrodes, a plurality of second internal electrodes, a plurality of first external electrodes(18a,18b), and a plurality of second external electrodes(19a,19b). The main body is made of a plurality of dielectric layers. The first internal electrodes and the second internal electrodes are arranged inside the main body by turns in between the dielectric layers, and are divided into a plurality of groups including at least a pair of first and second internal electrodes. The first external electrodes and the second external electrodes are formed on a surface of the main body. The first internal electrode and the second internal electrode of each group are respectively connected to the first external electrode and the second external electrode, and have at least two capacity values according to a selection of the first external electrode and the second external electrode connected to an external power line.
