BFC237354683

Film capacitors (also known as plastic film capacitors) are a type of capacitor that use conductive plastic films as the dielectric medium. They typically come in two varieties, polypropylene (PP) and polyester (PET) film capacitors. The BFC237354683 film capacitor is an example of a PP film capacitor.

Application Field

The BFC237354683 film capacitor is widely applied in high frequency AC circuits, such as lighting, switching power supplies, and frequency converters. It is suitable for various applications such as solar inverters, wind turbines, high frequency motor control systems, high-speed machines and even medical equipment. In addition, due to its high dielectric constant and excellent insulation properties, it can also be used in AC filters or high frequency resonant applications for signal processing.

Working Principle

Film capacitors have two electrodes separated by a dielectric material. When a voltage is applied to the electrodes, electrons enter the negative side of the capacitor and build up a negative charge on the negative plate, creating an electric field in the dielectric material. This electric field between the two plates induces a positive charge on the positive plate. This creates an electric potential difference, producing a capacitive effect.

The dielectric material used in film capacitors has a very high dielectric constant, resulting in a very high capacitance per unit volume. This makes the capacitor suitable for high-frequency circuits where a small volume can store a large amount of charge. The BFC237354683 capacitor in particular has a dielectric constant of 4.2 and a capacitance of up to 2700 pF.

As the electric field between the two electrodes generates a charge on the capacitor, the dielectric material also affects the performance of the capacitor. Film capacitors typically require a dielectric material with high insulation resistance and low dissipation factor for optimal performance. The BFC237354683 has a low dissipation factor, a high insulation resistance, and an excellent dielectric constant, making it suitable for high-frequency circuits.

In addition, the BFC237354683 film capacitor also has a high maximum operating voltage, making it suitable for high-voltage applications in harsh environments. Its robust construction also contributes to its durability and long lifespan, making it a great choice for applications in demanding working environments.
