Prior to being acquired by Littelfuse, Wickmann was a leading manufacturer of circuit protection components for the consumer electronics, industrial electronics, telecommunications and data processing markets for more than 80 years. Littelfuse acquired the Wickmann brand as part of its acquisition of Heinrich Industrie AG of Witten, Germany, in 2004.
The Wickmann product line includes miniature, sub-miniature, surface mount and other fuses that are used in a variety of electronic devices.
Wickmann has a strong position with consumer electronic and power supply manufacturers. The acquisition added TR and TE fuse technology to Littelfuse and strengthened our position in Europe. The TR and TE fuse category, which is used in power supplies for portable products such as mobile phones and laptops, was not manufactured by Littelfuse at that time. The Wickmann acquisition significantly increased our electronic revenues and strengthened our position in Europe.
