摘要： A capacitor connection structure of a power conversion device, includes a capacitor having a capacitor end face from which a positive electrode terminal and a negative electrode terminal protrudes that is deformed outward into a convex shape when the fuse is blown, a positive electrode-side main conductor and a negative electrode-side main conductor that are formed by a thick plate and that are connected to another electronic component at positions facing the capacitor end face; a positive electrode-side intermediate conductor that connects the positive electrode terminal to the positive electrode-side main conductor; and a negative electrode-side intermediate conductor that connects the negative electrode terminal to the negative electrode-side main conductor. When the capacitor end face is deformed into the convex shape, the positive electrode-side intermediate conductor and the negative electrode-side intermediate conductor are deformed along with inclination of the positive electrode terminal and the negative electrode terminal.

摘要： [Subject] To provide a highly-reliable and small-size chip component, e.g., a chip resistor having an accurate resistance value.[Solution] The chip resistor (10) includes: a substrate (11); a plurality of resistor elements each having a resistive film portion (20) provided on the substrate (11) and an aluminum-containing interconnection film portion (21) provided in contact with the resistive film portion (20); electrodes (12, 13) provided on the substrate (11); and a plurality of fuses (F) each having an aluminum-containing interconnection film portion integral with the aluminum-containing interconnection film portion of the resistor element and disconnectably connecting the resistor element to the electrodes (12, 13).[Effect] The resistance of the chip resistor can be adjusted at a desired resistance value by selectively disconnecting desired ones of the fuses. Since the fuses are formed in a minute layout pattern from an aluminum-containing interconnection film, the processing accuracy is improved in the disconnecting step.

摘要： A pocket within the molded casing of a solid electrolyte capacitor is of greater volume than a fuze passing through the pocket, thereby ensuring that the fuze will not reestablish its conductive path after being blown. The pocket is established between layers of polyester tape that insulate the cathode of the capacitor from its leadframe and protect the fuze from the molding material.

摘要： A fuse for a solid electrolyte capacitor is made of two exothermically alloyable metals such as aluminum and palladium. The fuse has a series electrical connection with and a thermal connection to the capacitor body. A defective and overheated capacitor section results in abnormally high currents so that the fuse temperature is elevated by ohmic self-heating and/or by the flow of heat from the overheated body. When the alloying temperature of the fuse is reached, the temperature of the alloying fuse momentarily becomes very high and opens essentially along its entire length.

摘要： An oil filled capacitor has an exothermically alloyable fuse strand within the closed housing that is filled with a dielectric oil. A circuit interruptor means is included within the housing that interrupts a capacitor section to housing terminal connection either in response to overpressure or to overtemperature within the housing, or both. The fuse strand is part of that connection and a portion of the fuse is located at the predetermined point of potential interruption so that any arcing that occurs across the gap of the opened connection will kindle the fuse which in turn will be completely obliterated and quench the arc.
