Abstract
A multilayer capacitor include dielectric layers stacked in a direction perpendicular to a mounting surface of a capacitor body, and internal electrodes and an equivalent series inductance (ESL) control pattern formed on upper and lower portions of the dielectric layers, respectively. The internal electrodes have an area larger than that of the ESL control pattern, and the ESL control pattern is exposed to a mounting surface of a capacitor body.

A multilayer capacitor, comprising dielectric layers stacked in a direction perpendicular to a mounting surface of a capacitor body, and internal electrodes and equivalent series inductance (ESL) control patterns formed on upper and lower portions of the dielectric layers, respectively,
- wherein the internal electrodes have an area larger than that of the ESL control patterns, and the ESL control patterns are exposed to the mounting surface of the capacitor body.
A multilayer capacitor comprising:
- a capacitor body including a plurality of dielectric layers stacked in a direction perpendicular to a mounting surface of the capacitor body;
- first and second external electrodes extending from opposing surfaces of the capacitor body in a length direction to portions of the mounting surface of the capacitor body, respectively;
- a plurality of first and second internal electrodes disposed to face each other, with at least one of the dielectric layers interposed therebetween in the capacitor body, and electrically connected to the first and second external electrodes, respectively;
- and
- a plurality of first and second equivalent series inductance (ESL) control patterns disposed at positions closer to the mounting surface of the capacitor body than the first and second internal electrodes, respectively, to face each other, with at least one of the dielectric layers interposed therebetween in the capacitor body, and exposed to the mounting surface of the capacitor body, to thereby be electrically connected to the first and second external electrodes, respectively,
- wherein the first and second internal electrodes have an area larger than that of the first and second ESL control patterns, respectively.
