Abstract: An electronic component includes a laminated body including dielectric layers and internal electrode layers, a first external electrode, a pair of second external electrodes, and a pair of insulating coating portions. The internal electrode layers include first and second internal electrode layers, the second internal electrode layers each include first and second extended electrode portions. A relationship of L1/L2>1.0 is satisfied when a length of a first contact portion with one second external electrode in contact with the first extended electrode portion in the length direction is L1, and a length of a second contact portion with the other second external electrode in contact with the second extended electrode portion in the length direction is L2.

Abstract: A monolithic capacitor includes a laminated body including stacked dielectric layers and substantially in the shape of a rectangular parallelepiped, and including a first surface being a mounting surface, a second surface opposite to the first surface, opposing third and fourth surfaces orthogonal to the first and second surfaces, and opposing fifth and sixth surfaces orthogonal to the first to fourth surfaces; capacitor electrodes disposed in the laminated body and each including a capacitive portion and a lead portion extending therefrom to at least one surface of the laminated body, the capacitive portions facing each other with dielectric layers interposed therebetween; and first and second outer electrodes disposed on at least one surface of the laminated body and connected to the lead portions. A gap between the first surface and the capacitive portions is greater than a gap between the second surface and the capacitive portions.

Abstract: A mounting structure includes an electronic component mounted on a circuit board. Land electrodes are disposed on a board body and are connected to outer electrodes of the electronic component through solders, respectively. A distance from each of the land electrodes to a top of the corresponding solder is not larger than about 1.27 times a distance from each of the land electrodes to an exposed portion of a capacitor conductor exposed at an end surface of the electronic component, the capacitor conductor being positioned closest to the circuit board.

Abstract: A multilayer ceramic capacitor includes a capacitor body and first to fourth outer connectors. The capacitor body includes dielectric layers and conductor layers, first and second principal surfaces facing each other in a height direction, first and second side surfaces facing each other in a length direction, and third and fourth side surfaces facing each other in a width direction. The first to fourth outer connectors cover portions of the first to fourth side surfaces, respectively. In a case where L0, W0, and H0 are maximum external dimensions of the multilayer ceramic capacitor in the length direction, the width direction, and the height direction, respectively, L0, W0, and H0 satisfy a condition of about 2.67≤L0/H0 and a condition of about 1/1.72≤L0/W0≤about 1.72.

Abstract: A multilayer ceramic electronic component includes a laminated body, a first external electrode, a pair of second external electrodes, and a pair of insulating coating portions. The pair of insulating coating portions extends in a laminating direction between each of the pair of second external electrodes and the first external electrode on a second principal surface, from the second principal surface to respective portions of a first side surface and a second side surface. As viewed from at least one direction in the laminating direction, an end of the first external electrode and pair of second external electrodes, which is located closest to a first principal surface, is located closer to the first principal surface than an end of the pair of insulating coating portions, which is located closest to the first principal surface.
