Among the global top three in the multibillion-dollar capacitor market, Rubycon is famous for compact yet powerful capacitors. Its miniaturisation technology led to the ubiquity of flat panel displays on a global scale. The company continues to bring industries to new frontiers as it turns 60 this year.
"We aspire to create the infinite future of electronics with a clear sense of improvement and innovation," says Shuichi Katsuyama, Rubycon president and chief operating officer.
The company's latest innovation in light-emitting diode (LED) lighting is an aluminium electrolytic capacitor that lasts up to 20,000 hours at 105 degrees Celsius. This service life is the longest so far reached in LED lighting.
Rubycon has 70 per cent of the global supply of capacitors for photo flash equipment. It is a top supplier in the LED lighting, automotive, home appliances and industrial equipment segments.
Among some 5,000 customers worldwide that rely on Rubycon are global brands such as Panasonic, Sony, Canon and Toyota. Taiwan's Delta Electronics, Lite-on Technology and Germany's Siemens and Bosch are also major overseas clients.
With its proven track record for durability and high quality, Rubycon's capacitors have come to greater use in power generation, especially in Europe's wind and solar energy systems. Rubycon is eyeing a greater role in the mainland's energy modernisation with its power capacitors. With heat resistance and low noise levels that far exceed industry standards, polymer multilayer capacitors also have great potential in the automotive, medical and lighting industries.
"Long-life capacitors play an important role in decreasing the material and environmental costs of technology in a broad base of industries. Such eco-friendly solutions embody Rubycon's Technology triangle philosophy of contributing to society and the future," Katsuyama says.
Rubycon's manufacturing process is fully in-house, from raw materials to machinery and assembly systems that are optimised for energy efficiency. Certified for ISO9001, ISO/TS16949 and ISO14001, the company's global manufacturing facility is based in Indonesia. It works closely with clients in developing advanced applications and new technologies at its factories in Japan.
Rubycon is exploring partnership opportunities in line with its expansion on the mainland, in India and Southeast Asia. It opened its office in Mumbai last year, and will open two more on the mainland next year in Chongqing and Chengdu.
"As a market leader in China, we want to keep on growing especially in helping shape next-generation systems," Katsuyama says. The company is open to co-development partnerships on the mainland.
