KYOTO, Japan -- March 18, 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.

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%^*4 compared with conventional
products. By introducing this newly developed MLCC to the market, Kyocera
hopes to contribute to further size reduction and service life extension of
industrial equipment.

Main Features

1. World's first 1206 size, 100V-rated MLCC with a maximum operating
temperature of 125°C and a capacitance of 4.7μF
Utilizing its long-accumulated material technology, Kyocera has developed a
new dielectric material by reducing the average diameter of particles by
approximately 20% and enhancing its uniformity of composition. This allows
Kyocera to minimize the degradation in dielectric properties such as
dielectric constants and insulation resistance against high voltage, even when
the thickness of a dielectric layer is reduced. As a result, Kyocera has
succeeded in developing the world's first 1206 size, 100V-rated MLCC with a
maximum operating temperature of 125°C and a capacitance of 4.7μF.

2. Excellent ripple-resistance
In addition to low ESR, an intrinsic characteristic of MLCC, this product
features a smaller size with high voltage resistance and high capacitance.
While aluminum electrolytic capacitors are currently widely used in the market
as smoothing capacitors for electronic circuits, this product exhibits
ripple-resistance^*5 even in frequency bands of more than several dozen kHz,
which cannot be achieved by aluminum electrolytic capacitors (e.g. ESR10mΩ at
50kHz, with a load of DC40V). This allows the capacitor to limit heat
generation in the power supply circuit and voltage fluctuation to low levels,
thus contributing to downsizing and enhancing reliability of industrial
equipment.

*3.   X7S (EIA): Temperature variation of capacitance is within ±22% from -55
      to +125°C.
*4.   Compared with conventional Kyocera materials. Based on research by
      Kyocera.
      Ripple-resistance refers to an allowable amount of AC components
      (current noise) superimposed on the DC voltage. When AC components flow
      into the capacitor, heat is generated due to DC resistance of the
*5.   capacitor (Equivalent Series Resistance: ESR), which may reduce service
      life in some cases. Therefore, it can be said that ripple-resistance is
      higher when ESR is low, as heat is not easily generated. As MLCCs
      essentially have a lower ESR than other capacitors such as aluminum
      electrolytic types, they feature superior voltage smoothing performance.
