WIMA has a long tradition in the field of passive electronic components. It was founded by Wilhelm Westermann in Unna/Westphalia in 1948. Within only a few years he extended his company into one of the leading specialists in capacitor production. WIMA is a privately owned company and the president today is Dipl.-Ing. Dipl.-Wirtsch.-Ing. Wolfgang Westermann. WIMA’s strength lies in the design and production of customized products requiring experience and highly developed expertise. Solutions can therefore be offered to all customer needs. 

Major customer groups are in automotive, consumer and industrial electronics and the lighting industry. Among others there are well-known and demanding customers like Bosch and Siemens with supply of worldwide facilities.
