Since its establishment in 1950, TAIYO YUDEN has always been driven by materials science, starting with ceramic capacitors and gradually developing into a hidden champion in the global electronic component field. Its development process can be divided into four stages, each of which focuses on technological breakthroughs and market expansion, ultimately forming an industrial pattern covering multiple fields such as communication, automotive, and consumer electronics.
1、 Technological foundation and product diversification (1950s to 1980s)
In 1950, Dr. Shouichiro Inoue founded Solar Induction in Tokyo, Japan, with barium titanate ceramic capacitors as its core product, quickly entering the high reliability electronic component market. In 1954, the company achieved commercialization of ferrite magnetic cores, further consolidating the technological foundation of passive components. In the 1960s and 1970s, solar induced electricity continued to innovate, launching products such as ultra small cylindrical ceramic capacitors (US type) and H-series inductors, gradually expanding into the fields of transistor radios and early consumer electronics.
1984 became a key turning point: the company mass-produced the world's first nickel electrode high-capacity stacked ceramic capacitor (MLCC), achieving a capacity of 1 μ F with a 3225 size, breaking through the bottleneck of miniaturization technology at that time. Afterwards, solar induced electricity continued to lead the trend of miniaturization of MLCC through material iteration and multi-layer technology optimization. In 1988, the company launched the world's first recordable optical disc "That's CD-R", setting a benchmark in the storage media market with the "Green Disc" series. DVD-R technology was commercialized with a capacity of 4.7GB in 1998.
2、 Globalization Layout and Breakthrough in RF Technology (1990-2000s)
In the 1990s, solar induced electricity accelerated its global expansion: in 1997, its Taiwan subsidiary obtained ISO14001 certification, pioneering environmentally friendly production; In 2001, the Bluetooth module passed Ver.1.1 certification and entered the wireless communication market. During the same period, the company made breakthroughs in high-frequency component technology. In 2003, it developed an ultra small ceramic chip antenna for UWB, and in 2004, it launched a disc substrate material recycling business, forming a "material product cycle" closed loop.
In 2005, the solar induced electricity was introduced into the radio wave method to strengthen the research and development capabilities of wireless equipment. In 2008, the world's first organic pigment recording layer blue light recordable optical disc was released, extending its technological reserves to the field of optical storage. At this stage, the company has built a complete industrial chain from passive components to modular products by vertically integrating ceramic materials, precision machining, and packaging technologies.
3、 Automotive Electronics and High end Market Challenge (2010-2020)
In the face of the wave of automotive electrification, Sun Induction focuses on high reliability automotive grade components: the Changzhou factory was established in 2019 and put into operation in 2023, specializing in the production of MLCC that meets the AEC-Q200 standard, with an upper working temperature limit of 150 ℃, covering full package sizes from 0402 to 008004. The company has simultaneously launched conductive polymer hybrid aluminum electrolytic capacitors, which combine low ESR and long lifespan characteristics to enter the power management system of electric vehicles.
In the field of 5G communication, solar induction relies on FBAR/SAW filters and LTCC integration technology to provide low loss, high bandwidth RF front-end modules. In 2021, the proportion of automotive and industrial equipment in the company's MLCC production capacity reached 43%, while the proportion of consumer electronics decreased to 19%, completing the strategic transformation of the market structure from C-end to B-end.
4、 Intelligence and Sustainable Development (2020s present)
Currently, solar induction is upgrading from a "component supplier" to a "solution provider":
Technical iteration: Develop 0.01mm micro MLCC, each capacitor containing hundreds of layers of dielectric, with a single layer thickness of only 1-2 microns, for application in wearable devices and medical electronics.
Capacity optimization: The Changzhou factory has become the world's largest MLCC production base. After completing vehicle certification in 2024, it will achieve full coverage of consumer grade to vehicle grade products.
Environmental Protection Strategy: Committed to reducing greenhouse gas emissions by 42% compared to 2020 by 2030, and reducing production energy consumption through ceramic formula improvement and process optimization.
Market response: Set up technical teams in Beijing, Shenzhen, Suzhou and other cities in China, promising to respond to customer needs within 24 hours and strengthen localized services.
Core competitiveness and industry status
The competitive advantages of solar induced electricity are reflected in three dimensions:
Materials Science: Independently developed ceramic formulas such as barium titanate and lead zirconate titanate to achieve high dielectric constant and high temperature stability.
Precision manufacturing: Multi layer technology can stack thousands of layers of media in a few millimeters of space, and MLCC products have a thickness of only 0.064 millimeters.
Vertical integration: Control the entire process from ceramic powder to finished product packaging to ensure product consistency and reliability.
As of 2025, the market share of solar induced MLCC ranks among the top three in the world, and products such as inductors and RF devices are widely used in leading companies such as Tesla and Huawei. The company is driving towards its annual sales target of 480 billion yen with the dual wheel drive of "material innovation+intelligent manufacturing", continuously consolidating its leadership position in the electronic components industry.
