Film capacitors are widely used in many practical circuits due to their wide range of characteristics. 474PSB152K4J film capacitors as a type of film capacitors are one of the most popular capacitors. It is a kind of polyester film capacitors with self-healing characteristic.

474PSB152K4J film capacitors have low internal, low dissipation factor and low temperature drifts. Therefore, they have excellent electrical properties over a wide frequency range and good stability. The superior frequency characteristic property of 474PSB152K4J film capacitors makes them very suitable for use in low-frequency 20kHz widespreading applications including consumer products and medical equipments.

A 474PSB152K4J paper capacitor consists of thin sheets of uniformly carburized self-healing paper with terminals, wrapped in a cylindrical aluminium container. The paper in the capacitor is dielectric which splits the positive and negative charge. Aluminium is also used to ensure electrical insulation. The aluminium electrolytic capacitor has two aluminium end caps, which are separated by paper spacers. This provides the necessary electrical insulation between the two sides of the aluminum casing. As the capacitor is constructed, it is vacuum sealed and hermetically sealed.

The working principle of 474PSB152K4J film capacitor is based on the electrostatic storage of energy in a dielectric material located between two metal plates. When a voltage is applied across the plates, electric charges are stored in the capacitor material. The electric charges build up until the voltage across the plates is equal to the applied voltage, and then they remain at the same value. The amount of charge stored in a capacitor is equal to the applied voltage multiplied by its capacitance rating. The higher the applied voltage, the greater the amount of charge which can be accumulated.

The charge stored on the capacitor can be released in the form of current if the capacitor is connected to a circuit with an electrical load. The current flows until the capacitor has released all of its stored energy, and then the capacitor voltage drops to zero. The capacitor can charge and discharge in an alternating manner, allowing it to act as a signal filter and noise suppressor. The capacitor can also be used to store energy and release it in a controlled manner, making it an important electrical component in applications such as power supplies and motor drives.

In summary, 474PSB152K4J film capacitors have wide range of applications in low frequency 20kHz widespreading. It has excellent electrical properties and good stability over a wide frequency range, and can be used in power supplies, motor drives and other applications.
