Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
The film capacitor manufacturing process for three products including plastic box, aluminum can or a customized solution (seen in Figure 2). Within this process, there are key steps to further analyze. Figure 2: Film capacitor manufacturing process. Source: TTI
The electrodes of metalized film capacitors consist of an extremely thin metal layer (0.02 μm to 0.1 μm) that is vacuum deposited either onto the dielectric film or onto a carrier film. The opposing and extended metalized film layers of the wound capacitor element are connected to one another by flame spraying different metals to the end-faces.
Film capacitors can be optimized through diferent materials and manufacturing methods. Capacitors are all unique; their fundamentals, the manufacturing processes, advantages and even technology trends are worth highlighting. There are diferent grades and applications critical to considering before choosing the best option.
The process of making an aluminum (Al) can film capacitor is similar except the round capacitor is not hard pressed; instead it is left round (Figure 11). Then, depending on whether the Al can is oil-filled or dry-filled, the capacitor goes through a process to place the bound capacitor inside the Al shell and fill with oil or resin.
These capacitors come with very specific advantages including non-polarity, a high insulation resistance, low dielectric losses and self-healing capability. Film capacitors can be optimized through diferent materials and manufacturing methods.
