Abstract

An electronic component includes an electronic component body and metal terminals. The electronic component body includes a base member and external electrodes. The base member includes two opposed end surfaces, two opposed side surfaces, and two opposed principal surfaces. The external electrodes are disposed on the end surfaces of the base member. The metal terminals are connected to the external electrodes by bonding with solder. A relationship of about 21≦Vc/Vh≦about 320 is satisfied where Vc is a volume of the electronic component body and Vh is a volume of the solder provided at one of the pairs of the external electrodes and the metal terminals.

Claims

1. A monolithic ceramic capacitor comprising:

an electronic component body including;

a base member including;

two opposed end surfaces;

two opposed side surfaces; and

two opposed principal surfaces; and

external electrodes disposed on the two opposed end surfaces of the base member; and

metal terminals that are connected to the external electrodes by solder;

wherein

a relationship of about 21≦

Vc/Vh≦

about 320 is satisfied where Vc is a volume of the electronic component body and Vh is a volume of the solder provided at one of the pairs of the external electrodes and the metal terminals.

2. The monolithic ceramic capacitor according to claim 1, wherein the volume Vh of the solder provided at one of the pairs of the external electrodes and the metal terminals is defined by the average value of the volumes of the solder at the two end surfaces of the electronic component body.

3. The monolithic ceramic capacitor according to claim 1, wherein the solder is Sn—

Sb solder and a content rate of Sb is in a range from about 5% and about 15%.

4. The monolithic ceramic capacitor according to claim 1, wherein the solder is located on portions of the external electrodes disposed on the two opposed end surfaces of the base member and the solder does not extend to any of the opposed side surfaces and the opposed principal surfaces of the base member or portions of the external electrodes disposed thereon.
