TAIYO YUDEN Achieves the Industry’s Largest Capacitance with its Low-Profile Ceramic Capacitors

Suitable for Small and Thin Mobile Devices with a Capacitance of 0.47 μF and the World's Thinnest Profile of 0.11 mm
Picture (PresseBox) (Tokyo, ) TAIYO YUDEN CO., LTD. announced today the commercialization of the low-profile multilayer ceramic capacitors PMK105 BJ474ML and PMC105 BJ474ML (both 1.0 x 0.5 x 0.11 mm, with height as the maximum value).

These products can be used in devices that are required to be small and thin, such as smartphones and wearable devices, for the purpose of decoupling IC power supply lines or embedded-parts multilayer wiring substrates and various modules. The capacitance enhancement technique TAIYO YUDEN has nurtured enables the capacitor products to achieve a capacitance of 0.47 μF at a height of 0.11 mm, which is the world’s thinnest profile for multilayer ceramic capacitors.

Production of this multilayer ceramic capacitor commenced at the company’s Tamamura
Plant (Tamamura-machi, Sawa-gun, Gunma Prefecture, Japan) from September 2016 at a production rate of 10 million units per month.

Technology Background

Multilayer ceramic capacitors are placed near IC devices mounted in a smartphone or a wearable device for the purpose of decoupling. In accordance with reductions in the size and thickness of devices and the need for improved functionality, the mounting area available for various parts is decreasing. There is a need to implement higher-density mounting, which includes mounting low-profile parts inside or at the back of the IC package and embedding them in the substrate, rather than using the conventional method of mounting parts on the printed circuit board. Furthermore, for stably driving the IC device, multilayer ceramic capacitors for the purpose of decoupling are required to have a larger capacity while maintaining their small form.

To address this market need, TAIYO YUDEN has commercialized the 1005-size multilayer ceramic capacitors with the industry’s largest capacitance of 0.47 μF in a 0.11 mm profile by refining the conventional capacitance enhancement technique to reduce the thickness of the external electrodes. Moreover, the PMC105 BJ474ML product has copper-plated electrodes, which are suitable for mounting on embedded-parts multilayer wiring substrates. We will continue to actively promote the development of low-profile multilayer ceramic capacitors with a smaller, thinner profile and a higher capacitance.

For decoupling IC power supply lines for embedded-parts multilayer wiring substrates and various modules, particularly in devices that are required to be small and thin, such as smartphones and wearable devices
