Rubycon Corporation was established in April 1952 as a manufacturer of electrolytic capacitors. The company owns a high-level manufacturing technology for electrolytic capacitors, has an extensive sales network, and a long expertise in conductive polymer materials plus business experience with PC-CONs (conductive polymer aluminum solid electrolytic capacitors). As electronic devices become increasingly digitalized, compact, and high-frequency, there is a growing demand for miniaturized capacitors that can offer low ESR and low impedance in high frequency zones. The trend toward lead-free soldering for mounting to PCBs means that superior heat resistance is also required. In response to these requirements, Rubycon is engaged in the design, manufacture, and sales of PC-CONs that employ the highly conductive and heat resistant conductive polymer polypyrrole (PPy) for the cathode.
