Film Capacitors

Film capacitors are widely used in power systems, lighting devices, telecommunication equipment, electronic toys, household appliances, and digital systems. A film capacitor, also known as a foil capacitor or film dielectric capacitor, is a type of capacitor using a thin plastic film as the dielectric. It may be constructed as a flat box, cylinder, or other shape. The film capacitor is widely used due to its superior characteristics, such as wide frequency characteristics, low losses, low temperature coefficient, and small size.

MKT1820215106 Application Field and Working Principle

The MKT1820215106 is a film capacitor, specifically designed to work in extreme temperatures and harsh environmental conditions. It is a Polypropylene Film Metalized capacitor with radial leads on the outside. The casing is made of plastic and finished in a black colour. This particular capacitor is capable of working at temperatures ranging from -40°C to +105°C and in humidity levels up to 95%.

The working principle of this film capacitor is the same as a traditional capacitor; two metal plates (conducting plates) separated by a dielectric (film). A voltage is applied to the two metal plates, and current flows in between. This creates an electric field that stores electrical energy. The dielectric film also serves to reduce the dielectric losses in power systems.

The MKT1820215106 capacitor has a capacitance of 1.8µF and an operating voltage of 50V. The phenomenon of electrical displacement is the main working principle of this capacitor. The electrical charge is accumulated on the plates due to the presence of a voltage difference across them; this charge acts as an additional charge that adds to the total charge of the capacitor. This additional charge increases the capacitance of the film capacitor, thus increasing its ability to store energy.

The MKT1820215106 capacitor is suitable for use in a variety of applications such as power supplies, switching circuits, audio systems, communication equipment, control systems, lighting systems, and many more. It is particularly used in applications involving extreme temperatures and humidity levels. The capacitor also has a low temperature coefficient, ensuring accuracy and repeatability. The small size of the capacitor makes it easier to design into a circuit.

The MKT1820215106 film capacitor is an efficient and reliable energy storage solution for a variety of applications. The capacitance and operating voltage of the capacitor make it an ideal choice for a wide range of devices. The low temperature coefficient of this film capacitor ensures accuracy and repeatability, making it suitable for use in extreme conditions. The high-quality construction and design of the capacitor also make it an attractive option for various applications.
