What TOKIN Corp does

TOKIN Corp, headquartered in Shiroishi, Miyagi Prefecture, Japan, is a manufacturer of passive electronic components serving automotive electronics, medical equipment, industrial machinery, consumer devices, and information and communications equipment markets. Founded in 1938 as Tohoku Metal Industries to commercialize KS Steel and Sendust alloy developed at Tohoku Imperial University, the company has accumulated 80+ years of materials science capability across magnetic materials (ferrite, nano-crystalline, Sendust), piezoelectric ceramics, and dielectric formulations. TOKIN became a wholly-owned subsidiary of KEMET Corporation in April 2017 (changing its name from NEC TOKIN) and now operates within the YAGEO Group following YAGEO's 2019/2020 acquisition of KEMET.

The company's product portfolio is organized into three core segments: capacitors (TOKIN polymer tantalum, supercapacitors up to 105°C AEC-Q200 rated, and KEMET/YAGEO ceramic, tantalum, aluminum, and film capacitors); EMC and noise components (AC/DC line filters, EMI cores including nano-crystalline split-type, noise suppression sheets under the Bustraleid brand, and metal composite power inductors rated to 180°C); and sensors and actuators (temperature, current, piezoelectric vibration, pyroelectric infrared, and laminated piezoelectric actuators). Supporting the product business, TOKIN produces electronic materials including ferrite tiles for wireless power transfer, permanent magnets (samarium-cobalt magnets used in JAXA Hayabusa spacecraft ion engines), shape memory alloys, and electromagnets for particle accelerators. Notable engineered components include the SC-XV Series automotive common-mode line filter (industry-first 1000V AC/DC AEC-Q200 compliant choke) and the T598 polymer tantalum capacitor rated at 125°C for 2,000 hours.

Revenue is generated through B2B hardware sales of components, with a sales-led go-to-market spanning direct sales offices in Tokyo, Nagoya, and Osaka; a Korean sales subsidiary; e-commerce via Zaiko Store and Chip One Stop distributor; and the global YAGEO Group distribution network. Manufacturing is distributed across Japan (Shiroishi, Toyama), Thailand (TOKIN Electronics Thailand), Vietnam (TOKIN Electronics Vietnam, established 1997), and China (TOKIN Electronics Xiamen). Pricing is quote-based and not publicly disclosed. Consolidated headcount stood at 5,257 (880 Japan, 4,377 overseas) as of April 2017. The company is led by Representative Executive Officer President Shigenori Koyama with William M. Lowe Jr. (former KEMET CEO) as Representative Chairman.
