Patent number: 12512242Abstract: In a multilayer coil component, a plurality of coil conductors are stacked in a coil axis direction. A connecting conductor connects the coil conductors adjacent to each other in the coil axis direction. First, second, and third coil conductors are arranged in order in the coil axis direction. A main body portion extends in a circumferential direction of the coil axis. Pad portions are connected to the main body portion, are connected to the first coil conductor via the connecting conductor, overhang from the third coil conductor in a direction away from the coil axis when viewed from the coil axis direction, and are inclined with respect to a virtual plane orthogonal to the coil axis direction.Type: GrantFiled: November 22, 2022Date of Patent: December 30, 2025Assignee: TDK CORPORATIONInventors: Yuya Oshima, Kenji Komorita, Takehiro Ishii, Kouichi Kakuda, Shigeshi Osawa, Yusaku Abe, Tsubasa Ozawa, Midori Kishimoto, Makoto Yoshino, Koki Ito, Masato Kudou

Patent number: 12347607Abstract: In the multi-layer coil component, the hole portion is provided in the vicinity of the side surface of the element body, and the distance from the tip position of the external electrode to the hole portion is shorter than the distance from the tip position of the external electrode to the coil. Therefore, when a crack is generated starting from the tip position of the external electrode on the mounting surface, the crack progress toward the hole portion located at a distance closer than the coil. Therefore, in the multi-layer coil component, splitting of the coil due to the crack can be prevented.Type: GrantFiled: March 28, 2022Date of Patent: July 1, 2025Assignee: TDK CORPORATIONInventors: Yuya Oshima, Kenji Komorita, Masayuki Suzuki, Yuudai Katou, Takeru Sasaki, Shigeshi Osawa, Takehiro Ishii, Kouichi Kakuda, Yukio Takahashi, Tsubasa Ozawa, Makoto Yoshino
