The German capacitor manufacturer FTCAP has expanded its portfolio in the area of high-voltage capacitors

The German capacitor manufacturer FTCAP has expanded its portfolio in the area of high-voltage capacitors. The company now offers film capacitors that enable a voltage of up to 120 KV DC, which makes them ideal for use in X-ray machines and high-voltage power supply modules, for example.

The new film capacitors for high-voltage applications are designed for flexible adaptation to the respective requirements: the edge steepness (dU/dt) can be changed individually as needed and the capacitors can also be implemented in diverse types. “We produce the housing ourselves, at the factory in Husum; custom designs are no problem. For example, the new film capacitors can easily be integrated in existing installation spaces,” explains Dr. Thomas Ebel, Managing Director of FTCAP. The innovative film capacitors are available with a voltage of up to 120 KV DC in a housing.

The newly developed vacuum casting technology achieves especially high-quality and homogeneous insulation, which reduces partial discharges to a minimum. The potting and encapsulation are resistant to high-voltage oil to guarantee a long service life. Because FTCAP always strives to convince its customers all along the line, each single film capacitor is subjected to extensive tests and measurements for quality assurance prior to delivery.



FTCAP Fischer und Tausche Capacitors has more than 70 years of experience in the development and production of capacitors used in diverse industries. The products include both film and electrolytic capacitors and FTCAP is one of the few companies to still manufacture all of its capacitors in Germany. In addition to standard capacitors in small and medium-sized quantities, the Husum-based manufacturer also offers special custom-made products for demanding applications: The company’s experts work in close cooperation with the customer to implement complex custom solutions. Since 2018 FTCAP belongs to the Mersen Group. The merger of the two enterprises will result in substantial growth potentials for both parties. The explicit goal is to offer innovative modules, in which FTCAP capacitors are optimised for use with busbars and heat sinks from Mersen.
