Ceramic capacitor and electronic component including the same

摘要

In a ceramic capacitor, first and second electrode terminals each include a bonded-to-substrate portion, a first bonded-to-electrode portion bonded to a first edge of one of first and second external electrodes, a second bonded-to-electrode portion bonded to a second edge of the one of first and second external electrodes and disposed at a distance from the first bonded-to-electrode portion in the first directions, and a connecting portion connecting the first and second bonded-to-electrode portions and the bonded-to-substrate portion. W1/W0 is about 0.3 or more, and h/L is about 0.1 or more.

1. A ceramic capacitor for mounting on a substrate, the ceramic capacitor comprising:
a capacitor body substantially made of a dielectric material, the capacitor having a substantially rectangular parallelepiped shape and including first and second end surfaces, first and second side surfaces, and first and second main surfaces, the first and second end surfaces extending along vertical directions and first directions perpendicular or substantially perpendicular to the vertical directions, the first and second side surfaces extending along second directions and the vertical directions, the second directions being perpendicular or substantially perpendicular to the first directions and the vertical directions, the first and second main surfaces extending along the first directions and the second directions; first and second internal electrodes disposed at an interval inside the capacitor body; a first external electrode disposed on the first end surface and electrically connected to the first internal electrode; a second external electrode disposed on the second end surface and electrically connected to the second internal electrode; a first electrode terminal having a first edge bonded to the first external electrode and electrically connected to the first external electrode and having a second edge bonded to the substrate; and a second electrode terminal having a first edge bonded to the second external electrode and electrically connected to the second external electrode and having a second edge bonded to the substrate; wherein the capacitor body is supported by the first and second electrode terminals at a distance from the substrate; each of the first and second electrode terminals includes:
a bonded-to-substrate portion bonded to the substrate;a first bonded-to-electrode portion bonded to an edge in one of the first directions, of one of the first and second external electrodes;a second bonded-to-electrode portion bonded to an edge in the other of the first directions, of the one of the first and second external electrodes, the second bonded-to-electrode portion being disposed at a distance from the first bonded-to-electrode portion in the first directions; anda connecting portion arranged to connect the first and second bonded-to-electrode portions and the bonded-to-substrate portion; and where a width along the first directions, of a portion of the ceramic capacitor except for the first and second electrode terminals is represented by W0 and a distance along the first directions between the first and second bonded-to-electrode portions is represented by W1, a ratio of W1 to W0 is about 0.3 or more.
