Film Capacitors

Film capacitors are a type of capacitors that make use of a film material as the dielectric in order to store electrical charge. They are primarily used in applications requiring a high voltage, high current or temperature-dependent characteristics, making them ideal for applications such as AC power supply filtering, motor drive systems, and for damping and absorbing impulse voltages. Film capacitors are also widely used for signal filtering in audio and video equipment, in passive crossover networks for loudspeakers and in antenna coupling devices.

Film capacitors also display a range of advantages over other capacitor types, including the fact that they are small and lightweight, highly stable over both time and temperature, and are regarded as higher precision than other capacitor types.

The MKT1820433404 capacitor is a polyester film capacitors and is a very popular type of film capacitor with a wide range of applications. It is most commonly found in consumer electronic applications, where its main purpose is filtering AC power so as to prevent the electronic device from interference or voltage spikes.

The MKT1820433404 capacitor is normally constructed of metallized polyester film. This type of dielectric material is very stable and has a good temperature coefficient, and offers excellent capacitance stability over frequency and signal amplitude. This makes it an ideal choice for applications such as high frequency power supplies, where the capacitor is required to provide very low impedance, high capacitance and high reliability.

The working principle of the MKT1820433404 capacitor is based on the fact that the dielectric material acts as a nonconductive barrier between the two plates of the capacitor, allowing a charge to be stored. When a voltage is applied across the terminals of the capacitor, the dielectric allows electric charges to flow, creating an electrical field, which ultimately stores energy. When the voltage is removed, the stored charge is released.

The MKT1820433404 capacitor is widely employed in a variety of consumer electronics and industrial equipment, where its ability to absorb and hold electrical charge makes it invaluable. It is suitable for applications such as AC power input filtering, motor drive systems, damping and absorbing impulse voltages, signal filtering in audio and video equipment, passive crossover networks and antenna coupling devices. The MKT1820433404 capacitor is also a popular choice for lighting applications, due to its high frequency response and high temperature coefficient.
