  In an electronic component including a multilayer capacitor, it is necessary to connect a plurality of multilayer capacitors in series in order to improve reliability such as withstand voltage. However, if the multilayer capacitors are directly connected to connect a plurality of multilayer capacitors in series, the mechanical strength at the connection location may not be sufficiently secured. For this reason, there is a demand for an electronic component that can increase the mechanical strength of a connection portion between a plurality of multilayer capacitors connected in series.

  An object of the present invention is to provide an electronic component that can increase the mechanical strength of a connection portion of a plurality of multilayer capacitors connected directly and in series.

  An electronic component according to the present invention includes a substantially rectangular parallelepiped first element body having a pair of first end faces facing each other and four first side faces extending in a facing direction of the pair of first end faces, and one first end face. A first terminal electrode having a first electrode portion disposed on one end surface; a second terminal electrode having a second electrode portion disposed on any one of the four first side surfaces; A first internal electrode disposed in the body and connected to the first terminal electrode; a second internal electrode disposed in the first body so as to face the first internal electrode; and connected to the second terminal electrode; A first multilayer capacitor, a pair of second end faces facing each other, and four second side faces extending in a facing direction of the pair of second end faces, and a first rectangular body having a substantially rectangular parallelepiped shape, A third terminal electrode having a third electrode portion disposed on the two end faces, and any one of the four second side faces A fourth terminal electrode having a fourth electrode portion disposed on two side surfaces; a third internal electrode disposed in the second element body; connected to the third terminal electrode; and a third internal electrode facing the third internal electrode A second multilayer capacitor including a fourth internal electrode connected to the fourth terminal electrode and disposed in the two elements, and disposed so as to face one first end surface and the other second end surface. A first metal terminal to which the first terminal electrode is connected; a second metal terminal to which the third terminal electrode is connected while being arranged to face the other first end face and the second end face of the other; The first multilayer capacitor and the second multilayer capacitor are disposed such that the first side surface on which the second electrode portion is disposed and the second side surface on which the fourth electrode portion is disposed are opposed to each other. The second electrode portion and the fourth electrode portion are connected.

  In the electronic component according to the present invention, the first metal terminal is connected to the first terminal electrode, the second metal terminal is connected to the third terminal electrode, and the second terminal electrode and the fourth terminal electrode are connected to each other. Therefore, the first multilayer capacitor and the second multilayer capacitor are connected in series.

  The first metal terminal is arranged to face one first end face and the other second end face, and the second metal terminal is arranged to face the other first end face and the one second end face. The first multilayer capacitor and the second multilayer capacitor are disposed such that the first side surface on which the second terminal electrode is disposed and the second side surface on which the fourth terminal electrode is disposed are opposed to each other. For this reason, the first metal terminal and the second metal terminal are spaced apart from each other in the facing direction of the first end face of the first multilayer capacitor and the facing direction of the second end face of the second multilayer capacitor.

  By the way, when the first metal terminal and the second metal terminal are arranged at a distance of about the length of the first multilayer capacitor in the longitudinal direction of the first element body, the first metal terminal and the second metal terminal However, compared with the case where the first multilayer capacitor is arranged in the longitudinal direction of the first element body and the length of the second multilayer capacitor in the longitudinal direction of the second element body is spaced apart from each other, Therefore, the mechanical strength against the force applied from is increased. Therefore, the mechanical strength of the connection location of the first multilayer capacitor and the second multilayer capacitor can be increased while the first multilayer capacitor and the second multilayer capacitor are connected in series.

  The second side surface facing the second side surface on which the fourth electrode portion is disposed may be opposed to another electronic device to which the first and second metal terminals are connected. In this case, the first multilayer capacitor is located above the second multilayer capacitor as viewed from other electronic devices. Therefore, the mounting area of the electronic component is small. Therefore, the electronic component can be mounted on another electronic device without increasing the mounting area.

  The first internal electrode and the second internal electrode are disposed in the first body so as to be orthogonal to the first side surface on which the second electrode portion is disposed, and the third internal electrode and the fourth internal electrode are You may arrange | position in a 2nd body so that it may orthogonally cross to the 2nd side surface where the electrode part is arrange | positioned. In this case, even when the number of internal electrodes in the first and second multilayer capacitors is increased, the length of the current path between the first internal electrode and the second internal electrode and the relationship between the third internal electrode and the fourth internal electrode An increase in the length of the current path is suppressed. As a result, an increase in ESL (equivalent series inductance) of the first and second multilayer capacitors can be suppressed.

  The second terminal electrode further includes a second electrode portion that is continuous with the second electrode portion and is disposed on each of the remaining first side surfaces other than the first side surface on which the second electrode portion is disposed. May further include a fourth electrode portion that is continuous with the fourth electrode portion and is disposed on each of the remaining second side surfaces other than the second side surface on which the fourth electrode portion is disposed. In this case, the second terminal electrode and the fourth terminal electrode can be connected regardless of the directions of the first and second multilayer capacitors. Therefore, the workability when connecting the first and second multilayer capacitors is improved.

  The first metal terminal includes a first part facing one first end face and the other second end face, a second part connected to another electronic device, and a third part connecting the first part and the second part. The second metal terminal includes the other first end surface and the fourth portion facing the second end surface, the fifth portion connected to the other electronic device, the fourth portion and the fifth portion. And a sixth portion connecting the two. In this case, the first and second multilayer capacitors are mounted away from other electronic devices by the distance between the first portion and the second portion and the distance between the fourth portion and the fifth portion. For this reason, it can suppress that the electrostrictive vibration generate | occur | produced by the mechanical distortion which arises in a 1st and 2nd multilayer capacitor to other electronic components.

As a result, an increase in ESL (equivalent series inductance) of the first and second multilayer capacitors C1 and C2 can be suppressed.
