Film Capacitor

Film capacitors generally refer to capacitors in which the dielectric layer is thin film, or in which the dielectric is a material resembling thin film.The dielectric layer used in a film capacitor is a polyester, polycarbonate or polypropylene material. Its working principle is based on the dielectric properties of a conductor. When a voltage is applied, electrostatic forces are created, with positive ions at the anode and negative ions at the cathode. The electrons in the ions then migrate towards the nearest metal plate, forming a double-layer of electrostatic charges in between the plates. These two layers have different electric potentials, and together create an electrostatic field.

MKT1813347634R film capacitors offer superior performance and are used for various applications. They can be used in audio and video applications to filter and demodulate signals. These capacitors also have low temperature coefficients and high selectivity, making them suitable for harmonic filters.

MKT1813347634R film capacitors are typically used in power electronics applications as they have low ESR (equivalent series resistance) and high voltage capabilities. Their low capacitance, low dielectric absorption and low dissipation factor make them ideal for use in high frequency switches, power supplies and motor drives, where high voltage and high frequency energy is generated.

MKT1813347634R film capacitors are also widely used in automation, telecom and consumer electronics circuits where low capacitance and high stability are highly desirable. In consumer electronics, they are used for power factor correction circuits and in audio circuits for power supply decoupling. They are also used as conventional electrolytic capacitors in high temperature applications where high current and high temperature rating is needed.

Since film capacitors are constructed using thin plastic layers, they do not suffer from electrolyte leakage, which is a common problem with electrolytic capacitors. Moreover, they are more stable over a wide range of temperature and voltage variations. Additionally, they have very good frequency characteristics and low inductance, making them ideal for use in high frequency applications.

In conclusion, MKT1813347634R film capacitors are generally used for filtering, control, decoupling, and power electronics applications. Their excellent frequency characteristics, high temperature rating, good stability, and low ESR make them an ideal choice for a variety of applications.
