Nichicon Corporation (ニチコン株式会社) is a manufacturer of capacitors of various types, and is one of the largest manufacturers of capacitors in the world, headquartered in Karasuma Oike, Nakagyō-ku, Kyoto, Japan. In 1950, it separated from the Nii Works Co., established itself as Kansai-Nii Works and completed its first factory by 1956. In 1961, it adopted the Nichicon name and has been using it, or a variant thereof, ever since.
In 2011 and 2012 Nichicon spun off several major factories into independent subsidiaries, and established representative branches in foreign countries, thus realigning its corporate infrastructure.[3]
Early 2000s capacitor issues
From 2001 to 2004, Nichicon produced defective capacitors ("HM" and "HN" series) that were used by major computer manufacturers, including Dell, Hewlett-Packard, and Apple.[4] No explanation has been given for the production runs of defective capacitors, but some sources claimed that these capacitors were either overfilled with electrolyte,[5]
