After the housing, epoxy is the second line of defense to protect the capacitor. Similar to plastic housing – which faces an environmental beating – epoxy resin is another necessary component for a long-lasting product. As shown in Table 5, a polyurethane resin is used in dry-type Al film capacitors.
struction. Here’s how to choose. For a metallized film capacitor, the capacitor plates are aluminum sprayed onto the dielectric fi m by thin-film vacu-um deposition. Compared to making the capacitor with sep-arate foil and film sheets, met-allizing enables smaller size, lighter weight, lower cost per microfarad and self-healing, but it also
Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life. The film capacitor uses a thin dielectric material with the other side of the capacitor metalized. Depending on the application, the film capacitor is rolled into thin films.
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.
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.
Film and foil capacitors are typically potted for internal protection with a very soft, gel type material. ELANTAS Europe offers a broad portfolio of epoxy and polyurethane compounds to ensure the safety and reliability of these capacitors, ranging from very soft to rigid and stiff materials.
