There are numerous advantages of MLCC, such as:

• Small parasitic inductance that offers better high-frequency performance compared to aluminum electrolytic capacitors.

• They offer better stability on temperature by relying on the temperature coefficient.

In 2021, the multi-layer ceramic capacitor industry generates $12.2 million revenue, and it is projected to advance at a rate of 12.3%, to capture 34.6 billion revenue in 2030. The high-capacitance MLCCs are integrated into electronic control units in automobiles led by the technical improvements in IoT equipment and infotainment, the development of connected cars, and the growing adoption of ADAS. Therefore, it leads to high demand for MLCCs.

MLCCs are highly required in electric vehicles compared to conventional vehicles that run on petroleum or gasoline. The growing road traction of electric vehicles leads to the increasing demand for MLCCs, which is five times higher than conventional automobiles. For instance, more than 9000 MLCCs are integrated into the TESLA Model 3 automobile, and the Model X and S are equipped with more than 10,000 MLCCs.

Ceramic dielectric capacitors are highly utilized for discriminating circuits, along with decoupling and bypass applications. They are also used for filtering and transient voltage suppression. Therefore, such factors lead to the increasing demand for multi-layer ceramic capacitors. Moreover, the X7R dielectric capacitor is the most significantly used capacitor led by its functioning at maximum temperature and temperature stability.

Moreover, the X5R MLCCs are widely used in mobile devices such as portable gadgets, gaming machines, smartphones, and automobile-mounted electronics. The growing popularity of such mobile devices leads to the increasing demand for the X5R multi-layer ceramic capacitors.

Electronic systems requiring high capacitance and high voltage rely on high-range voltage MLCC capacitors due to advanced ceramic dielectric ceramic thin layers as well as multi-layering methods facilitated in them.

They are used in varying applications such as lighting ballasts, high-voltage coupling capacitors, inverter circuits, and switched-mode power supply systems. In addition, mid-range voltage MLCCs offer numerous advantages such as no polarity, low leakage, low cost, and high capacitance-to-volume ratio which lead to their massive usage in various electronic systems. In addition, these capacitors offer lower ESR/ESL and higher mechanical strength compared to electrolytic capacitors.

MLCCs are also utilized in other sectors such as medical industrial equipment, telecommunications, and the military. They are widely employed in high-frequency RF devices, military communications devices, telecom base stations, and lasers due to the easy installation on circuit boards, enhanced assembly efficiency, and low inductance offered by shorter circuit tracks.

The major players operating in the MLCC industry are Taiyo Yuden Co. Ltd., Eyang Technology Development Co. Ltd., Knowles Capacitors, API Technologies Corp., Walsin Technology Corporation, Yageo Corporation, KEMET Corporation, and Kyocera Corporation.

Therefore, rising road traction of electric vehicles equipped with ADAS, IoT, and infotainment equipment leads to increasing demand for MLCCs.
