Multilayer capacitor including a dielectric breakdown prevention layer

摘要

A multilayer capacitor capable of having reducing electrical field intensity at external electrode edges while preventing occurrence of surface dielectric breakdown. This multilayer capacitor has a capacitor main body which includes a capacitance formation section having alternately laminated pluralities of internal electrodes and dielectric layers, and outer dielectric layer sections laminated on the upper and lower surfaces of the capacitance formation section. The capacitor also has external electrodes formed on respective opposite external side surfaces of the capacitor main body and each connected to certain ones of the internal electrodes. The outer layer sections each have respective dielectric breakdown prevention layers therein, each of which exhibits a carefully designed relative dielectric constant epsilon which is less than that of the dielectric layers in the capacitance formation section, and not more than 300, and has a thickness d [ mu m] satisfying the relation: d>(0.2x epsilon )+20.
