The electrodes of metallized film capacitors consist of an extremely thin aluminum layer (0.02μm - 0.1μm) that is vacuum deposited either onto the dielectric film or onto a carrier film. The dielectric film materials currently used in production range from 0.9μm to 20μm. The opposing and extended metallized film layers of the wound capacitor element are connected to one another by flame spraying different metals to the endfaces. The metal spraying process is also known as schooping. The terminals are connected to the end-faces by means of welding or soldering. For the production of metallized film capacitors Vishay Roederstein uses both the conventionally wound film and the stacked film (multilayer) technology. Stacked film capacitors, compared with wound film capacitors, exhibit a higher pulse load. Metallized film capacitors are typically manufactured in C-values ranging from about 1000pF to 10μF.
