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 issuesEdit

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][5] No explanation has been given for the production runs of defective capacitors, but some sources claimed that these capacitors were either overfilled with electrolyte,[4] or were constructed using electrolyte that was prone to leaking, causing premature failure in any equipment using them.[citation needed] This issue was not related to the Taiwanese capacitor plague.[4]

In 2010 Dell settled a civil lawsuit concerning its shipment of at least 11.8 million computers from May 2003 to July 2005 that used faulty Nichicon components and were prone to major failure.[6][7]
