Since the commercialization of a nickel-electrode high value multilayer ceramic capacitor in 1984 by TAIYO YUDEN, the company has continually led the market for these products and has promoted more compact, higher value multilayer ceramic capacitors through its advances in material science and multilayer technology. As we further our position as the worldwide leader for these products we are establishing a mass production technology for the 008004 size multilayer ceramic.
Production of this multilayer ceramic capacitor will begin within 2014 at the company’s Tamamura Plant in Gunma Prefecture, Japan, at a production rate of 10 million units per month.
Technology Background
For design of RF front end of wireless modules mounted on smartphones and wearable devices, noise control and improvement in efficiency are achieved through impedance matching that makes use of capacitors and inductors.
This requirement is even more pronounced in the design requirements for high-end smartphones. In order to comply with the various communications standards and frequency bandwidths for each country throughout the world, multiband is being promoted and the number of components is increasing. Further design requirements are driving products to be smaller and thinner and mounted components need to be smaller in size. As a result of a reduction in the size and thickness, as well as an improvement in performance of digital devices, multilayer ceramic capacitors are continuously becoming smaller and thinner with higher values. TAIYO YUDEN has always provided the market with the smallest, thinnest, and highest value multilayer ceramic capacitors in the industry. In 2005, we introduced and commercialized the EIA 01005 size. For our next step and as we continue our advancements and lead the market in technology we have established mass production technology, which includes the material technology, thin film technology, and multilayer technology of the world’s smallest class of 008004 size multilayer ceramic capacitor. Shipment of the evaluation samples has started April 2014.
We will continue to actively promote the product development of smaller, thinner, and higher value multilayer ceramic capacitors to address the ever-growing demand of the market.
■ Application
Impedance matching applications for the high frequency circuits of devices that are required to be small and thin, such as smartphones and wearable devices, and for decoupling of IC power supply lines in devices.
