Japan's Share of the Electrolytic Capacitor Market and Market Entrants

This article focuses on the position of Japanese companies among those participating in the electrolytic capacitor market. Nippon Chemi-Con, Nichicon, Rubycon and Panasonic are cited as participating companies, with a focus on the recognition and role of domestic companies.

Among the characteristics of Japanese companies, Nippon Chemi-Con is said to have a significant global share of large aluminum electrolytic capacitors for industrial equipment, with reliability and long-life design identified as its strengths. Nichicon is valued for the low impedance and heat resistance of its high-performance capacitors for automotive and audio equipment. Rubycon is noted for the low-ESR characteristics and stability of its products for video and communications equipment, while Panasonic is cited for achieving both miniaturization and higher capacitance with hybrid electrolytic and conductive polymer types.

Compared with overseas companies, Japanese companies are seen as having strengths in high reliability and long life, while their prices are considered relatively high. Samyoung and Samwha are described as having cost competitiveness, while Vishay, KEMET and EPCOS are said to be approaching Japanese companies while meeting quality standards for the European and US markets. The flexibility of price negotiations and short delivery times are also cited as strengths of overseas companies.

Regarding domestic demand trends, the main drivers are the increasing sophistication of electronic equipment, vehicle electrification and autonomous driving, and the advancement of medical equipment. Demand for 5G infrastructure and data centers is expected to expand. As a result, demand for highly reliable, high-capacity and compact electrolytic capacitors is expected to increase.
