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(Hybrid type)
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.The mission was originally scheduled to last for two years, but after four years of activity, which exceeded the original schedule, the mission was completed in December 2022.
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 ratio of electronic component costs in vehicles was around 3% in the 1980s, but has increased to around 40% in recent years, and is around 70% for electric vehicles due to the replacement of EVs and FCVs in the context of decarbonisation. Further increases are expected in the future. 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.
