Wickmann

Wickmann is a well-known, leading developer and manufacturer of innovative circuit protection products for the automotive, electronic and power industries. For over 80 years, Wickmann circuit protection products have solved both overcurrent and overvoltage issues for the widest range of applications.

Wickmann was a leading manufacturer of circuit protection components for the consumer electronics, industrial electronics, telecommunications and data processing markets. 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 Littelfuse 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.
