Abstract

The invention provides a surface-packaged capacitor and a manufacturing method of the surface-packaged capacitor. The surface-packaged capacitor comprises an anode element and a cathode element whichare isolated from each other, an anode outgoing line; a substrate, wherein an anode connecting groove and a cathode connecting groove are formed in the substrate, and conductors are arranged in the anode connecting groove and the cathode connecting groove; an anode bottom surface terminal which is connected with a notch in one side of the anode connecting groove, wherein one end of the electric conductor arranged in the anode connecting groove is connected with the anode leading-out wire, and the other end of the electric conductor arranged in the anode connecting groove is connected with theupper surface of the anode bottom surface terminal; a cathode bottom surface terminal which is connected with a notch in one side of the cathode connecting groove, wherein one end of the electric conductor arranged in the cathode connecting groove is connected with the cathode element, and the other end of the electric conductor arranged in the cathode connecting groove is connected with the uppersurface of the cathode bottom surface terminal. Through the above structure arrangement, the ESR value of the surface-packaged capacitor is reduced, and the reliability of the surface-packaged capacitor is improved.

Description

technical field [0001] The present application relates to the technical field of capacitors, in particular, to a surface mount capacitor and a method for manufacturing the surface mount capacitor. Background technique [0002] In current surface mount capacitors, the terminals are drawn out mainly by the cathode terminal and the anode terminal to lead the interior to the bottom terminal. This method has a small connection area and a single lead-out path, which makes the connection of the surface mount capacitor unstable and high in use risk, and this method makes the ESR (Equivalent Series Resistance, equivalent series resistance) value of the surface mount capacitor also large. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a surface mount capacitor and a method for manufacturing a surface mount capacitor, so as to improve the problem of "current surface mount capacitors are unstable in connection, high in use ri...
