A solid electrolytic capacitor includes a capacitor element, an anode lead terminalelectrically connected to an anode of the capacitor element, a cathode lead terminalelectrically connected to a cathode of the capacitor element, and a packagewhich is made of synthetic resin and hermetically seals the capacitor element. The lead terminals are embedded in the bottomof the package with the lower surfaces of the lead terminals exposed at the bottom surface of the package. The anode lead terminal and the cathode lead terminal are respectively formed with standing piecesandat portions corresponding to side surfacesof the package, and the standing pieces have respective outer surfaces exposed at the side surfaces of the package. This structure enhances the soldering strength and facilitates the visual inspection of the quality of the soldering.

Surface-mount solid electrolytic capacitor and process for manufacturing same

An electronic component is provided which comprises a resin package for enclosing inside parts. The package has a heat sensitive surface portion provided with a heat sensitive material which irreversibly discolors at a temperature higher than the soldering temperature for the electronic component. The component may be a solid tantalum capacitor, solid aluminum capacitor, diode or transistor which generates heat under abnormal operating conditions.

Heat sensitive electronic component

A capacitor apparatus incorporating a fuse incorporates a capacitor device having a first electrode and a second electrode; a fuse whose one end is connected to the first electrode; a first lead terminal connected to the other end of the fuse; a second lead terminal connected to the second electrode; and resin in which the capacitor device, fuse, and a part of the first and second lead terminals are molded. According to such features, fuming and ignition of the capacitor device due to an excessive current therethrough can be prevented without fail.
