The product development of Japan nippon starts from the basic research of materials needed for capacitors. Less well known to the outside world, Japan is the world's largest producer of aluminium foil, the main material that determines the performance of capacitors, and supplies other capacitor manufacturers. Capacitor materials research and development ability to achieve high quality and high credibility of products, is a major advantage of Japan. Based on the important technologies acquired in the process of developing aluminum electrolytic capacitors, Japan NIPPON has gradually expanded its business scope. Its products include multilayer ceramic capacitors and film capacitors, ceramic chokes, electrical circuit components, etc., and even involved in the field of optoelectronic machinery. Especially in recent years, large capacity supercapacitors have attracted much attention.
