Murata Manufacturing Co., Ltd. has introduced its highest capacitance value, 3-terminal multilayer ceramic capacitor in the 0402 inch size (1.0mm × 0.5mm) for decoupling in smart phones. This product achieves the world’s highest capacity (14uF) in this size, and is primarily intended for use in the power supply lines of APUs*1
. Sample shipping for this product has already begun, and mass production is scheduled to start from June 2018.
The power circuit of the processor uses a decoupling capacitor to reduce impedance, thereby suppressing fluctuation of the power voltage and increasing stability. As the processing speed (operating frequency) of the processor increases, suppression of impedance in a wide frequency band is needed.
A 3-terminal multilayer ceramic capacitor has lower ESL*2
than a conventional 2-terminal multilayer ceramic capacitor, so it can reduce impedance in a high frequency band with fewer components. Making use of this characteristic has resulted in expanding adoption in smart phones and other devices where compactness and high density are needed for mounted high speed processors.
This product uses leading-edge technology for MLCCs*3
to achieve the world’s highest capacity of 14uF in a 0402 inch size. The product will contribute to further gains in compactness and high density in smart phones.
