What are Film Capacitors?

Film capacitors are a type of high-voltage electrical component, usually cylindrical in shape. They serve a variety of useful purposes, such as energy-storage, voltage-drop reduction, supplying power to components, and eliminating noise. Film capacitors are used in a wide variety of applications, including automotive, renewable energy, and industrial.Film capacitors are made up of layers of thin sheets of plastic with metalized surfaces on either side. The metalized surfaces, which are typically aluminum or nickel, are separated by thin sheets of dielectric material, such as paper, polyethylene, or polypropylene. This structure gives the capacitor its high-voltage, low-resistance, and ultra-low self-inductance capabilities. The type of material used in the metalized layers determines the capcitor\'s value--specific capacitance and voltage-handling rating. Due to their thin, light-weight structure, film capacitors are often used where high-voltage requirements and space constraints demand a compact solution.
