TAIYO YUDEN has displayed strengths in technology and development since its earliest days. The history of the company cannot be separated from the history of advancements in the global electronics industry. Despite intense competition, we continue to grow together with our customers as a result of our unique approach and innovation. This, combined with our outstanding technical capabilities, makes TAIYO YUDEN a world leader in the electronics market.

Rutilcon HiK series

March 1950Hikohachi Sato establishes TAIYO YUDEN CO., LTD. in Suginami-ku, TokyoHikohachi Sato began researching ceramic materials before World War II. Based on the belief that product commercialization should start from the development of materials, he set about developing, commercializing and mass-producing barium titanate tubular ceramic capacitors. This laid the foundation for TAIYO YUDEN.

September 1950Commercializes barium titanate tubular ceramic capacitors and begins sales under the brand name RutilconTAIYO YUDEN used barium titanate in its capacitors on account of its high dielectric constant after a number of hurdles were cleared. Extensive efforts and numerous different paths were taken before Rutilcon capacitors were commercialized with an electrostatic capacity of 10,000pF, representing close to a double-digit increase in capacitance relative to conventional products.

September 1954Begins producing small ferrite coresTAIYO YUDEN accelerated the development of a small Intermediate Frequency Transformer (IFT) for use in transistor radios. The company’s technical team commercialized the product after focusing on nickel zinc ferrite as the component for the IFT. This product subsequently contributed to the development of transistor radios and televisions.

September 1964Establishes technical research laboratory in Haruna-machi, Gunma-gun, Gunma (currently in Takasaki-shi)Investments in R&D had been active in the electronics field since the mid-1950s. In 1960, after around 10 years in business, the company’s management policy adhered to bolstering research capabilities via establishing a new R&D structure featuring an independent research department.

1965Markets inductors (H Series) employing a uniquely developed ferrite coreUpon establishing material and production technologies for ferrite, TAIYO YUDEN then developed a coil (inductor) using ferrite produced by the company following a customer’s request. This became an area of comparative strength, with full-scale development and production carried out thereafter.

May 1967Establishes the first overseas subsidiary, TAIWAN TAIYO YUDEN CO., LTD.Around this time, production of such items as televisions and transistor radios as exports items was expanding, and in response to growing demand overseas, TAIYO YUDEN decided to construct a facility in Taiwan, where numerous major European and U.S. electronics manufacturers had already set up operations. Thereafter, the company started local production of tubular ceramic capacitors for IFTs.

March 1970Stock listed on Second Section of Tokyo Stock Exchange with an alternative listing on the First Section in 1973

July 1976Develops world’s first axial leaded ceramic capacitor Amid moves to conserve energy and electrical power after the first oil crisis in the mid-70s, electronics equipment makers began introducing automatic inserting machines for electronic components. Axial leaded ceramic capacitors were just the right size and shape for the machines. These components were widely used mainly in VTRs and audio equipment.

April 1977Commercializes axial leaded inductors In addition to capacitors, TAIYO YUDEN started to develop axial leaded type inductors as well. Since this product was not suited to the mass-production lines of existing items, TAIYO YUDEN developed suitable production machinery internally. Meanwhile, through a collaborative development project with machine makers, TAIYO YUDEN was able to overcome numerous hurdles, including the creation of a streamlined and integrated production line, which led to the successful commercialization of axial leaded inductors.

October 1977Develops world’s first tubular chip type ceramic capacitorIntegrating technologies amassed in the development of axial leaded ceramic capacitors and in long-established tubular ceramic capacitors for IFTs, TAIYO YUDEN developed the world’s first tubular chip type ceramic capacitor to meet the need for compact equipment and leadless components. It was primarily used in TV tuners.

Kuwata Building, TAIYO YUDEN’s founding sales office (Kanda Kamezumi-cho, Chiyoda-ku, Tokyo)

March 2010Makes TAIYO YUDEN Mobile Technology Co., Ltd. a subsidiaryTAIYO YUDEN took over the Communications Device Business of Fujitsu Media Devices Limited. This move strengthens our lineup of communications equipment such as FBAR/SAW devices and is expected to help expand business in line with growing markets.

May 2012Commercializes metal power inductor MCOILTM Using its independently developed metallic magnetic materials, TAIYO YUDEN developed the metal power inductor MCOILTM that achieves a balance between a miniaturized and low-profile form and high current response. This inductor is used in smartphones and tablet devices, in which the trend is moving toward devices that offer high functionality and are smaller and thinner. TAIYO YUDEN commenced mass production of a wire-wound type in 2012 and commercialized the world’s first multilayered type in December 2013.

Anechoic Chamber Test Facility

DVD-Rs, BD-Rs, CD-Rs

November 1998Establishes R&D CenterTo continue generating world-leading products based on our core strengths in technology and development, TAIYO YUDEN established our R&D Center modeled after cutting-edge, innovative laboratories. We have created an environment exclusively dedicated to research and development. In 2003, we constructed an Anechoic Chamber Test Facility (EMC Center) at the R&D Center. We are committed to actively accelerating research and development in the wireless communications field.

July 1984Commercializes the world’s first nickel electrode high-capacitance multilayer ceramic capacitorDemand for multilayer ceramic capacitors was forecasted to increase in line with the miniaturization of electronic equipment. Focusing attention on the compact, high-capacitance zone, TAIYO YUDEN leveraged its unique material and processing technologies to develop the world’s first multilayer ceramic capacitor using nickel for the internal electrode. This signaled the dawn of competition in the development of ever-smaller multilayer ceramic capacitors of high capacitance.

June 1986Opens EMC CenterCombating noise in electronic equipment became increasingly critical as miniaturization and multi-functionality progressed in the market. To this end, TAIYO YUDEN established the EMC Center to examine electromagnetic compatibility (EMC).

September 1988Announces release of the world’s first recordable CD-R compact disksWhen the 12cm audio disk was unveiled in 1982, TAIYO YUDEN started work on the development of optical recording media compatible with the CD. Taking a completely different approach, TAIYO YUDEN made a major breakthrough and succeeded in developing the world’s first CD-R, a name conceived of by the company. The technology used in the CD-R was subsequently deployed in other high capacitance recording media such as DVD-R and recordable Blu-ray Disc (BD-R).

June 1998Commercializes LB Series wire-wound chip inductors for power circuitsTAIYO YUDEN marketed its LB Series wire-wound chip inductors for power circuits featuring a unique new structure that totally eliminates wasted space. In the following year, the company realized the smallest wire-wound chip inductor in the industry at the time (2012 size). These products were widely employed in portable digital equipment such as mobile phones and digital cameras.

2000Simultaneous startup of four overseas production basesTo respond to increased demand for a wide array of multilayer products in such IT-related markets as mobile phones and PCs, from 1999 through 2000 TAIYO YUDEN built an overseas production structure consisting of four production bases in Malaysia, the Philippines, Korea and China. As a result, TAIYO YUDEN has established a stable supply structure that raises our global competitiveness and ability to provide an uninterrupted supply of components to the market.
