Rubycon Products Contributing to Promote DX of the Society through Electronics Technology

Nowadays, various devices & equipment around us are digitalized and equipped with Information Technologies, and the electronic devices & equipment are indispensable in the present-day Society. In the electronics industries, Capacitors are being of necessity, and Rubycon recently contributes to so-called Digital Transformation of the Society through electronics technologies by proposing and supplying Capacitors, our main Products, to various electronic devices & equipment.

Conductive Polymer Aluminum Solid Electrolytic Capacitors

Among Aluminum Electrolytic Capacitors, Conductive Polymer Aluminum Solid Electrolytic Capacitors have wider operating temperature limits than other types of Capacitors, and have various high performance characteristics such as compact, low ESR, and high-ripple current. This technology enables designing High Efficiency Power Supplies and enables Reduction-in-Number of Capacitors used which was never achieved with conventional types of Capacitors.  This not only realizes High Efficiency but also contributes to Resource Saving and De-carbonization through Miniaturization and Reduction-in-Number of Capacitors.

Example of Reduction-in-Number by using high performance Conductive Polymer Aluminum Solid Electrolytic Capacitors

Compared to conventional Aluminum Electrolytic Capacitors, Conductive Polymer Aluminum Solid Electrolytic Capacitors are capable of very high ripple currents. As an example, where six conventional Aluminium Electrolytic Capacitors are required, only one would be enough with the same performance, saving a much larger space on the Board and contributing to the Miniaturization of the Device.

Polymer Multi-Layer Capacitors, PMLCAP

PMLCAP, developed with our proprietary technology, achieves extremely ideal characteristics and contributes to the high performance of electronic devices.PMLCAP is a surface-mounted film capacitor that achieves a significant reduction in size compared to conventional film capacitors by adopting a revolutionary technology in which electrodes and dielectrics are formed by vacuum evaporation. Compared with high dielectric constant multilayer ceramic capacitors, which have excellent frequency characteristics and temperature characteristics, they have superior “bias characteristics”, “beat sound characteristics”, “harmonic distortion ratio”, etc. Its characteristics were found among developers and adopted for Mars Exploration Rover / Seismograph, which landed in the plains near the equator of Mars in November 2018. Since then, PMLCAP has been contributing as a sensing key part of ultra-sensitive seismograph to exploring the geological activities and internal conditions of Mars.

Aluminum Electrolytic Capacitors for Automotive Application

With the development of “C.A.S.E.” (*) in the Automotive Industries, Electronic Components installed in Automobiles have been increasing year by year.
(*) = “Connected, Automated, Shared and Electric”
The Cost % of Electronic Components to the whole Vehicle Cost used to be about 3% in the 1980s, then has being largely increasing in recent years up to 40%, and is still expected to further increase due to replacement by EVs as well as FCVs aiming for De-carbonization. Rubycon has been devotedly promoting development of advanced Aluminum Electrolytic Capacitors for Automotive Applications including Conductive Polymer Aluminum Solid Electrolytic Capacitors (PZ-CAP) through our intensive internal R&D activities.
