Publication number: 20240258036Abstract: An electronic component includes: an element body including first and second end surfaces opposing each other and a side surface coupling the first and second end surfaces; first and second internal conductors in the element body; a first external electrode on the first end surface; a second external electrode on the second end surface; and first and second external conductors on the side surface. The first and second external conductors are separated from the first and second external electrodes. The first internal conductor is electrically connected to the first external electrode and the first external conductor. The second internal conductor is electrically connected to the second external electrode and the second external conductor. The first external conductor is located between the first external electrode and the second external conductor. The second external conductor is located between the second external electrode and the first external conductor.Type: ApplicationFiled: November 29, 2023Publication date: August 1, 2024Applicant: TDK CorporationInventors: Yuichi NAGAI, Ken Morita, Kyohei Takata, Yasuhiro Okui, Yoshitaka Nagashima

Publication number: 20240177936Abstract: A multilayer electronic device includes an element body including an interior region and an exterior region and a pair of external electrodes. The interior region includes inner dielectric layers and internal electrode layers laminated alternately. The exterior region is disposed outwards from the interior region in a lamination direction. The pair of external electrodes is disposed on a surface of the element body and connected to the internal electrode layers. DRAa<DRAb<DRAc and DRBa>DRBb>DRBc are satisfied, where “RA” includes an element having a highest mole ratio among “RE” in the inner dielectric layers of a third region at a center of the interior region in the lamination direction, “RB” includes an element having a highest mole ratio among “RE” in a first region at a center of the exterior region in the lamination direction, and “RA” and “RB” are different from each other.Type: ApplicationFiled: October 31, 2023Publication date: May 30, 2024Applicant: TDK CORPORATIONInventors: Taku MURAKAMI, Nobuto MORIGASAKI, Takuma ARIIZUMI, Yoshitaka NAGASHIMA, Tsubasa AOKI

Publication number: 20240047136Abstract: A multilayer electronic device includes an element body and a pair of external electrodes. The element body includes an interior region in which inner dielectric layers and internal electrode layers are alternately laminated and an exterior region located outside the interior region in its lamination direction. The pair of external electrodes exists on surfaces of the element body. Main-phase particles in the inner dielectric layers and outer dielectric layers of the exterior region include a main component having a perovskite crystal structure represented by a general formula of ABO3. r1<r2<r1×4.0 is satisfied, in which r1 is an average particle size of the main-phase particles constituting the inner dielectric layers, and r2 is an average particle size of the main-phase particles constituting the outer dielectric layers.Type: ApplicationFiled: July 24, 2023Publication date: February 8, 2024Applicant: TDK CORPORATIONInventors: Taku MURAKAMI, Nobuto MORIGASAKI, Takuma ARIIZUMI, Yoshitaka NAGASHIMA, Masato KIMURA
