Publication number: 20140254067Abstract: Disclosed herein is a tantalum capacitor capable of improving equivalent series resistance (ESR) characteristic by increasing the bond between a tantalum wire and a tantalum powder. The tantalum capacitor according to the present invention includes: a tantalum wire; a tantalum powder having embedded a front end of the tantalum wire and then being sintered; and a rough part formed on a surface of the tantalum wire so as to strengthen a bond between the tantalum wire and the tantalum powder.Type: ApplicationFiled: August 1, 2013Publication date: September 11, 2014Applicant: Samsung Electro-Mechanics Co., Ltd.Inventors: Hee Dong Myung, Jeong Oh Hong, Hee Sung Choi, Kyoung Hwan Kim

Publication number: 20070279841Abstract: A chip capacitor which can be miniaturized with structural stability. In the chip capacitor, a capacitor device has a cathode layer formed on an outer surface thereof and an anode wire is protruded from a portion thereof. A cathode lead is electrically connected to the cathode layer. An anode lead is electrically connected to the anode wire through a weld reinforcement. A molding is configured to cover the capacitor device in such a way that the cathode and anode leads are only partially exposed. Protrusions are protruded from outer surfaces of the cathode and anode leads, respectively, thereby forming steps on the outer surfaces thereof. In the chip capacitor, the leads and molding are bonded with much greater strength, thus more structurally robust. Also, this prevents external moisture from penetrating inside the chip capacitor, thereby significantly enhancing moisture resistance.Type: ApplicationFiled: June 1, 2007Publication date: December 6, 2007Inventors: Jae Kwang Kim, Hee Dong Myung, Jae Jun Park, Gyu Hwang Lee
