Patent number: 9984798Abstract: Provided is a jumper or current detection resistor element having suppressed occurrence of connection defects resulting from the electromigration. The element (1) of the invention comprises a main body (11) consisting of a metal plate-shaped body, and terminal sections (12) provided at both ends of the main body; the terminal sections protruding from the main body, and both terminal sections provided with a mounting surface; and curved or cut surfaces (A, B, C, D, E) formed at periphery of the mounting surface. Both terminal sections are further provided with opposing surfaces at inside in direction of disposition of both terminal sections, and thickness of the opposing surfaces decreases from the mounting surface (13) to the main body (11).Type: GrantFiled: September 19, 2014Date of Patent: May 29, 2018Assignee: KOA CORPORATIONInventors: Hitoshi Amemiya, Satoshi Chiku, Takanori Kikuchi

Publication number: 20170162302Abstract: Provided is a current detection resistor, which has a jumper function and a low resistance resistor function at the same time. The resistor is a metal plate resistor, which comprises a resistor body consisting of a metal material and a pair of electrodes consisting of a metal material having higher conductivity than the resistor body, wherein the resistor body is bonded between the electrodes. The pair of electrodes comprises a first electrode and a second electrode longer than the first electrode, wherein a slit is formed in the second electrode so that a portion of the second electrode becomes a terminal for voltage detection. The end of the slit does not reach the resistor body. The first electrode and the second electrode are respectively provided with mounting portions connecting to wiring patterns, and the resistor body is formed in the vicinity of the mounting portion of the first electrode.Type: ApplicationFiled: June 8, 2015Publication date: June 8, 2017Applicant: KOA CORPORATIONInventor: Satoshi Chiku
