Abstract: An electronic device includes first and second capacitors, a case, a coil, and first to fourth conductive terminals. The first capacitor includes first and second terminal electrodes. The second capacitor includes third and fourth terminal electrodes. The case includes an accommodation recess for accommodating the first and second capacitors. The coil is separated from the first and second capacitors by a part of the case and disposed outside the accommodation recess. The first terminal is connected to the first electrode and partly disposed on a mounting-side bottom surface of the case. The second terminal is connected to one end of the coil and the second electrode and partly disposed on the surface. The third terminal is connected to the other end of the coil and the third electrode and partly disposed on the surface. The fourth terminal is connected to the fourth electrode and partly disposed on the surface.

Abstract: A ceramic electronic device includes a ceramic element body, a terminal electrode, and a lead terminal. The ceramic element body has an end surface and a lateral surface. The terminal electrode is formed on from the end surface to a part of the lateral surface of the ceramic element body. The lead terminal is connected to the terminal electrode by a connection member. The lead terminal includes an electrode facing portion disposed correspondingly to an end-surface electrode of the terminal electrode, an extension unit extending downward from a lower end of the electrode facing portion, and a step surface located between the electrode facing portion and the extension unit. The electrode facing portion has a recess dented in a direction away from the terminal electrode. A center of the recess is located below a center of the electrode facing portion in a height direction.

Abstract: A conductive terminal includes an inner electrode part, an opening edge electrode part, and a lateral electrode part. The inner electrode part is connectable to a terminal electrode of a chip component by being inserted along an inner wall of an accommodation recess of a case. The opening edge electrode part is formed continuously to the inner electrode part. The lateral electrode part is formed continuously to the opening edge electrode part along an outer surface of the case. The inner electrode part includes a base part, a curved part, and a continuous boundary part. The base part continues to the opening edge electrode part. The curved part is formed near a tip of the base part and protrudes away from the lateral electrode part. The continuous boundary part is formed between the base part and the curved part and continuously connects them.

Abstract: A ceramic electronic component of the present invention includes: a ceramic element body; a terminal electrode formed on from an end surface to a side surface of the ceramic element body; and a lead terminal joined to the terminal electrode by a solder. A fillet of the solder is formed between the terminal electrode of a side surface at the ceramic element body and the lead terminal, and a coating layer is formed on a surface of the lead terminal that is in contact with the solder. The coating layer is formed of a metal component having a contact angle with the solder smaller than that of the lead terminal.

Abstract: An electronic device includes chip components, a terminal connection body, conductive terminals, and a support member. Each of the chip components has a pair of end surfaces on which terminal electrodes are formed. The terminal connection body connects the terminal electrodes on one side of the chip components arranged next to each other in a parallel direction to the end surfaces. Each of the conductive terminals includes a connection part and a mount part. The connection part is connected with the terminal electrode of either of the chip components located on both ends of the chip components connected in series via the terminal connection body. The mount part faces the connection part and is connected with a mount board. The support member is disposed between the connection parts and the mount parts. The chip components are arranged so that the end surfaces face the mount board.
