In modern electronic devices, there is an inconspicuous but crucial component - Multilayer Ceramic Capacitor (MLCC). This tiny component plays an indispensable role in smart phones, computers, automotive electronics and other fields, and is called the ‘heart’ of electronic products.

Structure and working principle of MLCC

The basic structure of MLCC includes.

1.Ceramic dielectric layer: usually made of barium titanate (BaTiO3) and other materials. 

2.Metal Electrode Layer: Alternating internal electrodes, commonly used nickel or precious metals. 

3.External electrodes: Connect the internal electrodes and solder them to the circuit board.

The operating principle of MLCC is based on the capacitive effect: when a voltage is applied, positive and negative charges accumulate between neighbouring electrode layers, thus storing electrical energy.

Advantages of MLCC

High capacitance density: The multilayer structure enables MLCCs to achieve high capacitance values in a small volume.

Excellent high-frequency characteristics: Suitable for high-frequency circuits.

High Reliability: High temperature and vibration resistance, long service life.

Low ESR and ESL: Help to reduce circuit noise and improve efficiency.

MLCC Application Areas

MLCC plays an important role in many fields.

consumer electronics: smart phones, tablet PCs and other equipment used in decoupling, filtering.

Automotive Electronics: Used in in-vehicle infotainment systems, electric vehicle power systems, etc.

Industrial Control: Used for power stabilisation and signal processing in various industrial equipment.

Medical Equipment: Used in medical imaging equipment, monitors, etc.

Development trend of MLCC technology

1.Miniaturisation: As electronic products continue to miniaturise, MLCCs are also developing towards smaller sizes. 

2. High capacity: Used in various industrial equipment for power stabilisation and signal processing.

3.High Reliability: Developing new MLCCs that are resistant to high temperature, high pressure, and high humidity. 

4.Environmentally friendly materials: research and development of lead-free, halogen-free and other environmentally friendly MLCC.

MLCC Market Overview

MLCC market shows continuous growth.

The global market size is expected to exceed USD 15 billion by 2025.

Japan, South Korea, and Taiwan manufacturers dominate the market.

Emerging segments such as 5G, IoT, and new energy vehicles are driving demand growth.

Summary

The importance of multilayer ceramic capacitors as an indispensable basic component in electronic products is often underestimated. With the continuous progress of electronic technology, MLCC will continue to move towards more miniaturisation, higher capacity, higher reliability of the direction of development, for the future innovation of electronic products to provide solid support. In this microcosm, MLCCs are quietly providing a steady stream of energy for our digital lives.
