Lead terminals for aluminum electrolytic capacitors business
Capacitors are electronic components that are indispensable for the operation of electrical appliances. In particular, "aluminum electrolytic capacitors" are large-capacity capacitors of choice, featuring a large volume of electrical charges that can be stored.
The lead terminals Kohoku Kogyo manufactures for aluminum electrolytic capacitors are important components that connect electronic substrates and capacitors. The Company has a global market share of over 40% on a volume basis and over 60% on a value basis, both the top share in the world.
Optical components and devices business
Optoelectronics and optical technologies, which utilize the actions and properties of light, are used in all areas including information and communication equipment, inspection equipment, and medical equipment. While Kohoku Kogyo provides optical components and devices for all kinds of optical components equipment, its optical isolators for submarine cables carry special weight.
For long-distance submarine cables, optical amplifiers are used to amplify and control the attenuated light. Kohoku Kogyo's optical isolators are used in these optical amplifiers. The Company has the world's top share of over 50% for optical isolators for submarine cables.
