A solid electrolytic condenser includes a condenser element, an anode wire including one end inserted into the condenser element, a cathode drawing layer formed on outer side of the condenser element, terminal reinforcements arranged respectively under opposite side portions of a bottom surface of the condenser element, a liquid epoxy resin filled in spaces between the terminal reinforcements and between the bottom surface of the condenser element and top surfaces of the terminal reinforcements, a molding part surrounding the condenser element while exposing the other end of the anode wire, an end portion of the cathode drawing layer, and bottom surfaces of the terminal reinforcements, and anode and cathode terminals formed by a plating layer provided on the bottom surfaces of the terminal reinforcements and on opposite side surfaces of the molding part. The liquid epoxy resin includes fillers of a smaller size than those in the molding part.

Solid electrolytic condenser with enhanced volumetric efficiency

A solid capacitor according to an aspect of the invention may include: a capacitor device having an anode lead wire extending from one side thereof; a case molding the capacitor device and exposing the anode lead wire to the outside thereof; cathode and anode lead frames exposed on the outside the case and electrically connected to the capacitor device; a reinforcement interposed in the case between the anode lead wire and the anode lead frame so as to support the capacitor device and electrically connecting the anode lead wire and the anode lead frame; and a resin shielding part applied to the exposed portion of the anode lead wire to prevent the infiltration of foreign substances through the anode lead wire.

Solid capacitor

The present invention relates to a solid electrolytic capacitor and a method for preparing the same. There is provided a solid electrolytic capacitor in accordance with the invention including a capacitor element with anode polarity therein and a cathode layer formed on an outer surface thereof; an anode wire with an end portion protruding on one surface of the capacitor element; a cathode lead layer formed on the other surface the capacitor element; a molding part surrounding the capacitor element to expose the protruding end portion of the anode wire and an end portion of the cathode lead layer; and an anode terminal and a cathode terminal formed by a plating layer at both sides of the molding part. It is possible to save preparation cost by simplifying a structure and a preparation process of the solid electrolytic capacitor.

Solid electrolytic capacitor and method for preparing the same

A solid electrolytic capacitor includes a capacitor element surrounded with a cathode layer, an anode wire inserted into the capacitor element, a cathode terminal electrically connected to the capacitor element by being positioned at one side below the capacitor element, an anode terminal defining a space between the capacitor element and a top surface thereof and is electrically connected to the anode wire by being positioned at the other side below the capacitor element, a conductive paste coated being thicker toward an inside of the capacitor element, thereby electrically connecting the capacitor element to the cathode terminal and broadening the space, and a fixing film closely coupled to a bottom surface of the conductive paste. A molding unit wraps the capacitor element and the fixing film in a state of closely adhering the conductive paste and the cathode terminal to top and bottom surfaces of the fixing film, respectively.
