Smartphones need to pack a lot of electronic functions into a small chassis, and the capacitors need to be as small as possible. For this reason, most of the capacitors used in smartphones are MLCCs, which excel in miniaturization, and there are now more than 1,000 MLCCs in each high-end, state-of-the-art smartphone.

Murata Manufacturing Co., Ltd. has introduced its largest capacitance 3-terminal multilayer ceramic capacitor in the 05035 inch size (1.2mm×0.9mm) and 0402 inch size (1.0mm×0.5mm) for decoupling in smartphones.
Tantalum capacitors are often used as the capacitor connected to the power line of PA (=Power Amplifier) for GSM on smart phones. In this report, we evaluate replacing the tantalum capacitor (Ta-Cap) with a ceramic capacitor. We purchased a smartphone and evaluated it.
Ceramic capacitors have low ESR and low ESL characteristics. Therefore, the impedance of a ceramic capacitor (22uF/6.3V/0603size) is smaller than that of a Ta-Cap (100uF/6.3V/1206size) over 100kHz range. Thus, the ceramic capacitor has a better noise suppression effect at a high-frequency range.
To ensure stable operation of these electronic circuits, many capacitors are used to supply power and eliminate noise. Smartphones need to pack a lot of electronic functions into a small chassis, and the capacitors need to be as small as possible.
Ceramic capacitors have good performance for noise suppression because the ESR and ESL of ceramic capacitors are lower than Ta-Cap. Ceramic capacitor has low temperature rise performance because the ESR of ceramic capacitors is lower than Ta-Cap. Breakdown voltage of ceramic capacitors is higher than Ta-Cap.
In general, these capacitors are required to have low leakage current, high quality factor, high power capability and high linearity. For instance, tunable capacitors for use in antenna systems are designed to offer excellent RF performance, high linearity, and low power consumption.
