Murata's Application/Solution Design Technology (Capacitor Design Technology)

Technical Explanation

Murata’s capacitor design technology consists of a combination of multiple techniques that enable performance enhancement and adaptability to diverse applications. In particular, with a focus on Multilayer Ceramic Capacitor, Murata leverages proprietary material selection and Monozukuri expertise to achieve high performance and high quality.

In material design, Murata uses high-dielectric materials such as barium titanate (BaTiO₃). Through ultra-fine particle control and processing technologies that ensure high-density and uniform material distribution, Murata realizes thin dielectric layers. This approach enables simultaneous miniaturization and increased capacitance while maintaining high reliability. In addition, material properties are carefully adjusted according to application requirements, optimal specifications are defined, and tailored design proposals are provided.

In Monozukuri technology, Murata ensures product uniformity and reliability by combining high-precision processing technologies—such as proprietary material dispersion technology, thin-film forming technology, and firing technology—with rigorous quality control.

Technological Strengths

Murata’s strength in capacitor design technology lies not only in supplying components, but in directly solving customer challenges from an application and solution perspective.

Murata has a precise understanding of the electrical characteristics and environmental resistance required for each series within its extensive Multilayer Ceramic Capacitor lineup. For smartphones and communication devices, designs emphasize high frequency performance and miniaturization. In contrast, for automotive, industrial equipment such as servers, and space applications, Murata provides application specific designs that ensure high temperature resistance, high voltage endurance, and long term reliability.

Murata also analyzes the roles of capacitors in power supply stabilization, noise suppression, and signal rectification and smoothing. Based on this understanding, capacitors are designed to match specific circuit configurations and load conditions. As a result, Murata goes beyond supplying individual components and delivers solutions that address customer challenges such as energy efficiency improvement and extended product lifetime.

Examples include high voltage capacitors for xEV battery management systems, low loss capacitors for 5G communication base stations, and high reliability capacitors for medical devices and space applications.

By continuously refining its technology in line with evolving applications, Murata contributes to value creation for both customers and markets through solution oriented capacitor design.

Technological Advancement

Murata's capacitor design technology has evolved over decades to meet the needs of each era, cultivating advanced technical capabilities applied across diverse fields.

In the 1970s, starting with leaded capacitors, we established core technologies such as stacking and thin-film processes, and began designing and producing Multilayer Ceramic Capacitor.

From the 1980s onward, with the proliferation of mobile phones and personal computers, demands for miniaturization and higher capacitance intensified. In response, we refined our unique material and Monozukuri technologies, such as controlling the particle size of ceramic particles in high-dielectric-constant materials and thin-layer stacking processes. As a result, we successfully developed capacitors that achieved high capacitance while enabling miniaturization. As a technological pioneer in the fields of high capacitance and miniaturization, we have led the industry.

In the 2000s, advances in environmental compliance made lead-free technology essential, and we swiftly adopted it. Simultaneously, for automotive and industrial equipment applications, design technologies evolved to withstand high-temperature and high-voltage environments, strengthening our product offerings in these sectors.

In recent years, 5G Communications and next-generation xEVs demand even higher-performance, more durable capacitors. Murata is advancing materials development and Monozukuri utilizing new technologies to enhance performance. Furthermore, to provide custom solutions tailored to customer needs, we are strengthening close communication.

Moving forward, we will continue innovating capacitor design technology to meet the evolution of electronic devices, promote materials development and Monozukuri for a sustainable society, and keep creating new value.
