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: An electronic component includes an element body, an external electrode, and a metal terminal. In the metal terminal, a base includes a first surface and a second surface opposing each other, and a pair of third surfaces coupling the first surface and the second surface. A first metal layer is disposed on the first surface and connected to solder with which the external electrode and the metal terminal are connected together. A second metal layer is disposed on the second surface. A coating layer is disposed on each of the third surfaces. The first metal layer and the second metal layer each include an outermost layer containing Sn. Each of the coating layer includes an outermost layer lower in solder wettability than the respective outermost layers of the first metal layer and the second metal layer.

Abstract: An electronic component includes: a substrate; a plurality of multilayer capacitors mounted on a first main surface of the substrate; and a sealing part formed of a resin and sealing the plurality of multilayer capacitors. A first external electrode and a second external electrode of the multilayer capacitor are mounted on the substrate by solder. At least a part of adjacent multilayer capacitors overlaps each other when viewed from a direction in which a pair of side surfaces of an element body are opposed to each other, the direction being along the first main surface of the substrate. In the adjacent multilayer capacitors, stacking directions of a plurality of internal electrodes are the same, and a distance between the adjacent multilayer capacitors is ½ or less of a height of the multilayer capacitor mounted on the substrate.
