The Leading Edge of R&D

Enhancing the competitiveness of front-end modules*

Improve the development of SAW/FBAR devices and EOMIN® components

SAW/FBAR components are primarily used in smartphones as well as other mobile electronics devices. These products are quickly becoming an essential component in mobile telecommunications products. EOMIN® is an embedded-parts multilayer wiring substrate. It uses a copper core to provide low noise and heat dispersion qualities. These EOMIN® modular devices can greatly reduce the overall size of conventional modules.

As smartphones incorporate increasing functionality and multiband capabilities, the number of individual components they require is steadily increasing. At the same time users are demanding that the handsets be smaller and thinner. TAIYO YUDEN’s SAW/FBAR devices and EOMIN® products can be used to create highly functional front-end modules which can respond to these market needs.

TAIYO YUDEN uses its advanced product development technology and production technology to supply a multitude of high value-added super-high-end products, and is expanding production capacity accordingly. R&D efforts will continue to focus on SAW/FBAR devices and EOMIN® products.

Electronic Components

Capacitors

Multilayer ceramic capacitors

The Company has improved its dielectric materials technology, thin-film and high capacity technology, and miniaturization capabilities to develop dielectric layers that are less than 1 micron in thickness and has mass-produced these products on a consistent basis. The Company’s multi-layering technology is approaching a 1000-layer capability, allowing TAIYO YUDEN to introduce and mass produce new capacitor products in the EIA 1206 size (3.2mm x 1.6mm) and EIA 1210 size (3.2mm x 2.5mm) range, both with a high capacitance of 220μF.
Looking ahead, we will apply these technologies to expand production of new products for the smartphone market.

Energy devices (capacitors)*

TAIYO YUDEN has developed the world’s smallest polyacene capacitors, for use in smartphones and for backup purposes in digital cameras. The Company has begun mass production of a coin-type 3.8mm-diameter x 1.1mm device, the smallest in the industry, and a rectangular 3.2mm x 2.5mm device, and has also begun mass production of low-profile, low-impedance polyacene capacitors. With the utilization of a two-layered electric capacitor structure and a lithium ion-coated anode, the Company has developed a cylindrical lithium ion capacitor which offers improved energy precision. Development work on a low-profile lithium ion capacitor is continuing. The Company will continue to develop superior new products that meet market needs in the energy device market. This market is expected to enjoy strong growth in the future.

*From the fiscal year ending March 2013, TAIYO YUDEN changed the product segment to the "Other Electronic Components" segment.

Ferrite and Applied Products

Multilayer chip inductors

TAIYO YUDEN is expanding its lineup of multilayer choke coils for DC-DC converters used in the expanding mobile electronics market. The Company has begun mass production of miniaturized, EIA 0603 size (1.6mm x 0.8mm) products which have a low profile of just 0.33mm in height. In the market for high-frequency multilayer inductors, used in the high-frequency circuits of mobile phones, TAIYO YUDEN developed EIA 0201 size (0.6mm x 0.3mm) and EIA 01005 size (0.4mm x 0.2mm) products which offer the best Q-factor characteristics in the industry. These products are in mass production. As technology continues to progress, the Company intends to launch even smaller and higher-function products.

Wire-wound inductors

Surface-mounted coil inductors used in power supply circuits are another focus of development for TAIYO YUDEN. Of particular note is the choke coils used in DC-DC converters produced for the growing smartphone market. To address strong market demand for low-profile products, the Company has begun mass production of 2mm x 2mm products. In response to the demand for even smaller products with large power outputs, the Company has used its technological know-how in developing new materials and advanced production technology to develop and mass produce the MCOIL® metallic power inductor. In the future, the Company plans to expand its lineup of MCOIL® products and increase production to further enhance competitiveness and product breadth. The Company will also continue working to develop new products by vigorously expanding its product lineup to meet market needs.

Modules

Multifunctional modules

A strong market demand for power-conserving components has prompted TAIYO YUDEN to work on the development of power source technology which reduces power consumption. Meanwhile, the Company is developing LED technology for use in both lighting applications and as a backlight unit for flat screen television sets. This technology provides the Company with several competitive advantages. In the future, the Company will continue working to address power conservation needs, developing multifunctional modules that have superior compactness, a low profile and high efficiency. One way to further reduce power consumption is to reuse energy in circuits. TAIYO YUDEN is developing new applications for power sources, and its own in-house IC control technologies for power sources, creating a stronger and more competitive product lineup.

Wireless communication modules

In the growing market for short-range wireless communications, TAIYO YUDEN has developed a multitude of products from small, low-profile modules and its own antenna modules, to meet customer needs with an emphasis to develop a wide range of products that reflect market demand.
