High-Frequency MLCC: From Basic Component to Core Technology in the 5G Era

2025-02-23

Multilayer Ceramic Capacitors (MLCCs), it is also called a monolithic capacitor, have evolved alongside the advancements of the electronics industry. From simple structures in the 1960s to today's high-frequency, high-Q products, the technological evolution of MLCCs has always been in sync with the progress of communication technologies. In the 5G era, high-frequency MLCCs have become indispensable core components in communication equipment.

We will have deep discussion of high Q MLCC, from their background, market demand(which application will use high frequency MLCC) , and HONGDA Capacitors’ high Q mlcc.

I. The Technological Evolution of MLCCs

Early MLCCs were primarily used in low-frequency circuits, with BaTiO3 as the main dielectric material, resulting in relatively low Q values. With the development of mobile communication technology, MLCCs transitioned from low-frequency to high-frequency applications and from standard Q values to high-Q values. In the 1990s, the rise of microwave communication spurred the development of high-frequency MLCCs, leading to the emergence of new materials and manufacturing processes.

Breakthroughs in high-frequency MLCC technology are primarily reflected in improvements in dielectric materials. New ceramic materials such as MgTiO3 and CaTiO3, combined with precise doping modifications, have achieved high Q values and stable temperature characteristics. Electrode materials have shifted from traditional Pd/Ag to purer silver electrodes, reducing high-frequency losses.

II. Market Demand for High-Q MLCCs

1. 5G Communication Equipment

High-Q MLCCs are critical components in 5G communication devices, particularly in RF modules, antenna tuning, and filters. Their low-loss characteristics significantly improve signal transmission efficiency and reduce power consumption. The large-scale deployment of 5G base stations and the rapid upgrade cycle of smartphones have created substantial demand for high-Q MLCCs.

2. Internet of Things (IoT) Devices

The proliferation of IoT devices has further expanded the application scenarios for high-Q MLCCs. In smart homes, industrial IoT, and other fields, high-Q MLCCs ensure the reliability and stability of wireless communication. As IoT networks grow, the demand for high-performance MLCCs in sensors, connectivity modules, and edge devices continues to rise.

3. Automotive Electronics

The automotive industry, particularly with the rise of electric vehicles (EVs) and advanced driver-assistance systems (ADAS), is another major driver of high-Q MLCC demand. These applications require components that can operate reliably in harsh environments while maintaining high performance.

4. Market Growth Projections

The global market for high-Q MLCCs is expected to reach $2 billion by 2025, driven by the rapid adoption of 5G, IoT, and automotive electronics. This growth is further fueled by the increasing complexity of electronic devices and the need for higher performance in smaller form factors.

III. High Q MLCC Capacitor Trends

1-- Miniaturization and Portability: Trend towards smaller and more portable devices

The market demand for lighter and thinner terminal equipment and complete functions has promoted the development of MLCC in the direction of miniaturization and small size.

On the one hand, consumers are keen on "lightweight and thin" mobile electronic devices, driving the miniaturization of electronic products. On the other hand, as smart phones become more comprehensive and richer in functions, it is expected that the electronic circuits in the fuselage will increase substantially. Therefore, it is necessary to further reduce the volume of capacitors such as MLCC in order to implant more electronic components in the body of a mobile phone that is shrinking. In 2008 and 2016, the MLCC used in smartphones was dominated by 0402 and 0201 size series products, respectively. In the future, 01005 and 008004 series will occupy a dominant position.

2-- Rising Popularity of 5G Technology: Demand for capacitors with high frequency and stability

The working frequency of MLCC has entered the millimeter wave frequency range. In order to meet the high performance and multi-function requirements of electronic circuits, the working frequency of LSI is getting higher and higher, which also proposes a higher level of low impedance power supply. Requirement, the market has become more urgent for MLCCs with low impedance and low inductance ESR/ESL that can be used in broadband (MHz-GHz).

IV. Competitive Landscape of Major Manufacturers

1. Established Players

Companies like American Technical Ceramics (ATC), Johanson Technology, and Knowles have long dominated the high-end market for high-Q MLCCs, known for their superior performance and reliability. Japanese manufacturers such as Murata and TDK also hold significant shares in the mid-to-high-end market, leveraging their extensive technological expertise and patent portfolios.

2. Emerging Competitors

Chinese manufacturers, particularly HONGDA Capacitors, have made significant strides in high-Q MLCC technology. Through continuous innovation, HONGDA Capacitors has developed high-Q MLCC products that can compete with those from ATC and Johanson. HONGDA Capacitors offerings match international standards in terms of Q value, temperature characteristics, and reliability while offering cost advantages. This breakthrough is reshaping the competitive landscape of the high-Q MLCC market.
