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. A maximum thickness of the first external electrode on the second principal surface is larger than a maximum thickness of the pair of second external electrodes on the second principal surface. The maximum thickness of the pair of second external electrodes on the second principal surface is larger than a maximum thickness of the pair of insulating coating portions on the second principal surface.

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: An electronic component includes a multilayer body, first to fourth outer electrodes, a pair of first insulating coating portions, and a pair of second insulating coating portions. The pair of first insulating coating portions is in at least one of a state in which inner end portions are in contact with the third outer electrode and a state in which outer end portions are in contact with the first outer electrode and the second outer electrode. The pair of second insulating coating portions is in at least one of a state in which inner end portions are in contact with the fourth outer electrode and a state in which outer end portions are in contact with the first outer electrode and the second outer electrode.

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.

Abstract: An electronic component has dimensions (length×width×thickness) of about 0.6 mm to about 1.0 mm×about 0.3 mm to about 0.5 mm×about 0.07 mm to about 0.15 mm. An area of a triangle defined by a first hypothetical straight line being in contact with the top of a portion of an outer electrode positioned on a first main surface at a center in the width direction and extending in the length direction, a second hypothetical straight line being in contact with the top of a portion of the outer electrode positioned on the first end surface at the center in the width direction and extending in the thickness direction, and a third hypothetical straight line being in contact with the outer electrode at the center in the width direction and being inclined at about 45° with respect to the first and second hypothetical straight lines is about 450 μm2 or larger.
