Film Capacitors

Film capacitors, also known as plastic film capacitors or film dielectric capacitors, are a type of capacitor that uses a thin plastic film as the dielectric. The film is usually a polyester, polycarbonate, polypropylene, polystyrene, or other similarly thin plastic material. The film is used to provide capacitance value, which is determined by the amount of film used. The dielectric constant of the film is usually between 4.0 and 6.0, depending on the thickness of the film and the film\'s composition.

The MKP1839310403 is a film capacitor that is designed for high voltage applications. It is a 2-terminal, surface-mountable device with a rated voltage of up to 10kV and a temperature range of -40°C to +125°C. It has an insulation resistance of more than 10 GΩ and a capacitance of 0.2 pF to 270 μF.

The main application fields of the MKP1839310403 are medical, aerospace, automotive, industrial, telecom, military, radio-frequency (RF) and general-purpose applications. It is used in various applications such as EMI/RFI suppression, power-line filtering, voltage division, noise/signal conditioning and energy storage.

Working Principle

The MKP1839310403 works by forming an electric field between two layers of plastic film. The film is then charged by the electric field created when a positive and negative voltage is applied to the different layers of dielectric film. This creates a polarized electric field, which stores energy in the form of an electric charge between the two layers of film. The electric charge is stored until the electric field is reversed, which releases the stored energy.

The MKP1839310403 is designed to provide a high level of stability over a wide range of temperatures and frequencies. It is also designed to provide excellent resistance to moisture, chemicals, and tracking. The device has an insulation voltage rating of 4000V, and is UL 94 V-0 rated for flame resistance. Its high voltage qualities make it ideal for use in medium and high-voltage applications requiring high insulation and good reliability.

In conclusion, the MKP1839310403 is a film capacitor designed for medium and high voltage applications, with high insulation resistance and excellent reliability. It is used in a variety of applications, including EMI/RFI suppression, power-line filtering, voltage division, noise/signal conditioning and energy storage. It is designed to provide excellent stability over a wide range of temperatures and frequencies, as well as resistance to moisture, chemicals, and tracking.
