Kyocera Develops World's First 1206 Size, 100V-Rated Multilayer Ceramic Capacitor with Maximum Operating Temperature of 125°C and Capacitance of 4.7μF

Achieving smaller size with high voltage resistance and high capacitance

KYOTO, Japan — (BUSINESS WIRE) — March 17, 2013 — Kyocera Corporation (NYSE: KYO)(TOKYO:6971) announced that it has succeeded in developing a new multilayer ceramic capacitor (hereinafter referred to as "MLCC") achieving a smaller size with high voltage resistance and high capacitance, mainly for use in industrial equipment. The company will begin mass production in March 2013.

The new product (CM316X7S475M100V), developed by enhancing dielectric materials with Kyocera's vast material technology, is the world's first*1 1206 size, 100V-rated MLCC with a maximum operating temperature of 125°C and a capacitance of 4.7μF. Compared with Kyocera's conventional 1210 size products*2 meeting equivalent specifications, the mounting surface of this MLCC is reduced by approximately 30%, thus contributing to downsizing and greater design flexibility as well as longer service life in industrial equipment.

Product name CM316X7S475M100V
Size 1206 size (3.2×1.6×1.6mm)
Features X7S (EIA)*3
Capacitance 4.7μF
Rated voltage 100V DC
Mass production schedule March 2013
Production facility Kagoshima Kokubu Plant

(Kagoshima Pref., Japan)

While MLCCs have advantages in terms of small size and extended service life compared with other types of capacitors, reducing size while maintaining high voltage resistance and high capacitance is difficult, as properties such as dielectric constants and insulation resistance degrade when applying high voltage to dielectric materials. Hence, aluminum electrolytic capacitors are often used for electronic circuits applied in power supplies of industrial equipment, which have high voltage resistant and high capacitance specifications such as a rated voltage of 100V and a capacitance of 4.7μF. In recent years, however, there are increasing needs for smaller industrial equipment products with longer service lives.

To respond to such needs, Kyocera has developed a 1206 size MLCC, achieving a smaller size with high voltage resistance and high capacitance. This product was developed by utilizing the company's proprietary material technology, which included improvements such as reducing the size of particles in dielectric materials by approximately 20% <
