Horizontally mounted capacitor module and electronic device including same

An electronic device comprising:

• a printed circuit board (PCB) having principal surfaces horizontally extending in a first direction and a second direction perpendicular to the first direction and including a mounting area, a first contact terminal, a second contact terminal and a third contact terminal;
• a case configured to be horizontally mounted on the PCB at least partially within the mounting area and including a first side surface, a second side surface opposing the first side surface, a first electrode pad and a second electrode pad disposed at the first side surface, and a third electrode pad disposed at the second side surface;
• and
• an electrolytic capacitor including a dielectric extending in the first direction, a first electrode and a second electrode spaced apart from the first electrode in the second direction,
• wherein the electrolytic capacitor is mounted on the case by connecting the first electrode to the first electrode pad and connecting the second electrode to the second electrode pad, and
• the case is horizontally mounted within the mounting area of the PCB by connecting the first electrode pad to the first contact terminal, the second electrode pad to the second contact terminal, and the third electrode pad to the third contact terminal.

A capacitor module configured to be horizontally mounted on a printed circuit board (PCB), the PCB having an upper surface and a lower surface horizontally extending in a first direction and a second direction perpendicular to the first direction, the capacitor module comprising:

• a case including a frame, a first side surface, a second side surface opposing the first side surface, a third side surface connecting the first and second side surfaces, a first electrode pad and a second electrode pad disposed at the first side surface, and a third electrode pad disposed at the third side surface;
• and
• a cylindrical electrolytic capacitor including a dielectric extending in the first direction, a first electrode contacting the first electrode pad and a second electrode contacting the second electrode pad,
• wherein the first electrode pad is spaced apart from second electrode pad in the second direction, and the frame substantially surrounds side surfaces of the cylindrical electrolytic capacitor.
