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 (series HM and HN) that ended up being used by major computer manufacturers, including Dell, Hewlett-Packard, and Apple.[4][5] No overall reason was ever proven 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 fluid that was prone to pop and leak fluid, causing premature failure in any equipment using them. This issue was not related to the contemporaneous Taiwanese "Capacitor Plague".[4]

In 2010 Dell settled a civil lawsuit for 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]
