Film Capacitors

Film capacitors, also known as paper capacitors, dielectric film capacitors, polyester capacitors, polypropylene capacitors, and plastic film capacitors, are electronic components made of dielectric polymer films. They have dielectric properties which separate the positively-charged and negatively-charged conductors in electrical circuits, allowing the flow of electric currents for various applications.

BFC238304134 is a type of film capacitor. This capacitor can be used for many applications, including those involving signal, power, and audio. The film capacitor has superior noise characteristics, and its dielectric properties allow for greater power efficiency.

Application field

BFC238304134 is suitable for AC and DC voltage applications. It can be used for the filtering of noise and signal processing. It is applied in automotive, consumer electronics and industrial equipment. It can also be used in motor control, audio and radio transmitters and receivers, as well as other products such as microwave ovens, fans, and telecommunication equipment.

This film capacitor can also be used in switching power supplies, UPS systems, and other voltage stabilization applications. Its function is to reduce the ripple of the output voltage, thus providing more stable power output for various types of electrical equipment. It can also be used in rectifier circuits for the same purpose.

Working Principle

The working principle of a film capacitor is based on the capacitive reactance property of electrical charge. The capacitor stores the charge and releases it back to the connected circuit in a timely manner. The capacitor consists of a film separator, two conductors, and a dielectric. The film is electrically insulating and releases the charge back to the circuit when needed. The two conductors create an electrical field when they get connected to the power source, and this field creates electric charge on the film. The charge on the film is opposed by the conductors, producing a net capacitance. The capacitor is able to store the electrical charge and regulate the voltage across the circuit.

The capacitance of a film capacitor is defined by the physical materials of its construction. The dielectric, thickness and area of the film, and the type of metal used for the conductors are all factors affecting the capacitance value. In order to have a high capacitance, a thinner film is used with the same area, thereby reducing the amount of electrical field required to create the required amount of charge.

The working frequency of a film capacitor is much higher compared to a regular ceramic capacitor. This is due to the high capacitance value of the dielectric. The frequency range depends on the dielectric and the type of material used for the conductors.

BFC238304134 is a film capacitor which has a wide range of applications in the signal, power, and audio industries.
