Rubycon products contribution to society

Rubycon products contribute to society through power electronics technologies

Urgent global themes such as energy issues are faced by societies. Core technologies to control energy with countermeasures to avoid escalation of global warming with power electronics are of primary importance. Rubycon is proposing capacitors to various power conversion devices to contribute higher efficiency, longer life and miniaturization.

«Conductive Polymer Aluminum Solid Electrolytic Capacitor»

Conductive polymer aluminum solid electrolytic capacitors have a wider temperature range, are more compact, have lower ESR, and higher resistance to ripple current than other aluminum electrolytic capacitors. These features enable high-efficiency power supply design and can contribute to the reduced number of parts. The net result of this capacitor technology is energy savings improved efficiency.

«Power Film Capacitor»

Voltage and current of main circuits have been increased to improve efficiency in power electronics. Most notably, in applications such as solar/wind power and automotive. Demand of large film capacitors (referred to as power film capacitors) is increasing. We are addressing deposition technology and low ESL (inductance) designs to improve efficiency and improve miniaturization.

«Screw Terminal Type Aluminum Electrolytic Capacitor»

Screw Terminal Type Aluminum Electrolytic Capacitor is used to main circuit of power electronics together with power film capacitor.
We are downsizing dimensions and raising withstand voltage with our independent development of new electrolytes and adoption of high capacitance etched foil.
Stud screw type capacitor has efficient heat radiation structure and high resistance to ripple current, so as to contribute to efficient package and downsizing of equipment.
We are further addressing to development of new electrolyte and foil for higher voltage use, which is important to circuits with the next-generation power electronics semiconductor.

«Electric Double Layer Capacitor»

Electric double layer capacitors use "electric double layer" produced on the boundary between the electrode and electrolyte (as dielectric) for storing electric charges. This capacitor realizes quick charge-discharge cycles as well as long life since there aren't chemical reactions to store charges. This capacitor is ideal for applications requiring momentary large current such as power assist and energy regeneration. If the capacitor is used as the main power for rechargeable equipment, maintenance is reduced.
