Film Capacitors

Film capacitors, or polyester, polypropylene, or polystyrene capacitors, are electrical components which generally use a thin plastic film as the dielectric. This film is wrapped in a metal foil, and then the combination is wound into a coil, giving the component its cylindrical shape. These capacitors can come in sizes ranging from as small as 0.033 inches in diameter up to several feet in length, and can have capacitance values ranging from a few picofarads up to several microfarads.

QXK2E334JTP7ZHFL Application Field and Working Principle

QXK2E334JTP7ZHFL film capacitors are used in many different electrical applications, such as power electronics, motor control, power supply, and protection circuits. These capacitors are especially popular for their light weight, low cost, and high performance for power applications. Additionally, film capacitors offer various advantages in terms of temperature stability, humidity resistance, and long life.Film capacitors work on the same principle as any other type of capacitor – in order for a current to flow through the capacitor, a voltage has to be applied across it. This application of voltage causes the dielectric material inside the capacitor to become polarized; it results in the build-up of electrical charge on the metal foil. The intensity of the electric field which develops in the dielectric material varies with the applied voltage, and this, in turn, changes the capacitance of the capacitor.

The structure and packaging of QXK2E334JTP7ZHFL also play an important role in their performance and application field. Generally, these capacitors are available in axial or radial configurations, and possess radial leads that can be soldered. QXK2E334JTP7ZHFL are also available in both plastic and metallic cases, and the capacitors themselves can feature non-inductive winding for better performance. Additionally, the capacitors are generally operated over a wide temperature range, from -25°C to +85°C, making them suitable for many different applications.
