AI Customer ServicePolymers in Film Capacitors - The Next Generation Material is available! Polypropylene is the polymer of choice for most film capacitors, but there is an inherent high temperature limit for its usage. New polymer materials are therefore required to overcome these temperature limitations.
The dielectric material used in film capacitors is typically either polyester, polystyrene, or polypropylene, and the electrodes are made of metal foil. Film capacitors are known for their stability, reliability, and low distortion, making them ideal for use in audio circuits.
New polymer materials are therefore required to overcome these temperature limitations. Accordingly, a new class of engineering materials, EPN (Ethylene-Propylene-Norbornene), has been developed for capacitor films, combining the advantages of polypropylene and cyclic olefin copolymers.
Film capacitors are one of the most common types of capacitors used in electronics systems today. The most widely used types of film capacitors include polyester, polycarbonate, polystyrene, polypropylene, polysulfone, and Teflon capacitors. A comparison chart of various film capacitors is shown in Table 1.
Polyester film capacitors, also known as Mylar capacitors, are a popular choice, featuring polyester as their dielectric material. Available in both film and foil as well as metallized varieties, they offer an economical solution with voltage capacities ranging from 50VDC to 1000VDC.
Teflon film capacitors match polystyrene’s performance and excel at high temperatures. These capacitors are moisture-resistant with a low dielectric absorption of around 0.02%. Teflon film capacitors have higher price limits and are mostly used in mission-critical applications such as aerospace.
