Problems solved by technology

If the electrode cross-sectional area of ​​the connection portion to the ground terminal of the second internal electrode is reduced, the ESL will increase, resulting in a problem of degraded noise removal characteristics.
That is, there is a problem that insertion loss characteristics deteriorate

Abstract

The invention provides a capacitor having good insertion loss characteristics and a method for manufacturing the capacitor. The capacitor includes a capacitor body made of a dielectric, a first internal electrode, a second internal electrode, a first signal terminal, a second signal terminal, and a grounding terminal. The first and second signal terminals are connected to the first internal electrode. The grounding terminal is disposed on the outer surface of the capacitor body so as to be connected to the second internal electrode. The grounding terminal is connected to the ground potential. The grounding terminal includes a plating layer which is disposed on the capacitor body and which is connected to the second internal electrode.

Description

technical field [0001] The present invention relates to a capacitor and a method of manufacturing the same. Specifically, it relates to a capacitor having a pair of signal terminals and a ground terminal and a method of manufacturing the same. Background technique [0002] Conventionally, a three-terminal type capacitor such as that described in Patent Document 1 and the like is known. In general, a three-terminal capacitor has a rectangular parallelepiped ceramic body. First and second internal electrodes are arranged inside the ceramic body. The first internal electrodes and the second internal electrodes are arranged to face each other. First and second signal terminals are formed on both end surfaces of the ceramic body. The first and second signal terminals are connected to the first internal electrode. On the other hand, a ground terminal connected to the second internal electrode and connected to a ground potential is formed on a part of the side surface of the ce...
