ECQ-B1122JF

Film capacitors are capacitors that utilise a film as their dielectric material. The layers of film can be any number of materials that vary from a polymer type to a charged ceramic coating. This article will discuss the ECQ-B1122JF application field and operating principle, while exploring how it relates to other film capacitors.The ECQ-B1122JF belongs to the ECQ series of film capacitors, which are widely used in many applications such as television sets, sound amplifiers, and other audio equipment. These capacitors have useful properties such as high insulation capacity, high dielectric strength, and good stability. The ECQ-B1122JF in particular is specifically designed for audio frequency use.The operating principle behind the ECQ-B1122JF is similar to other film capacitors. It has two metal plates separated by a thin dielectric layer, usually made of plastic film. When a voltage is applied, a charge builds up and forms an electric field, creating an electrostatic force between the plates. This force stores electrical energy in the form of an electric field, allowing it to remain relatively stable until it is discharged.In operation, the ECQ-B1122JF behaves much like other film capacitors. As the electric field between the two metal plates increases, the capacitance of the capacitor increases as well. The power stored in the capacitor increases with the amount of charge and voltage, allowing it to absorb more electrical energy and reduce the amount of power loss. The ECQ-B1122JF offers excellent performance even under high-frequency conditions.The ECQ-B1122JF has a temperature coefficient of capacitance that ranges from +31ppm/°C to +62ppm/°C, depending on the size of the component and the type of dielectric material used. This temperature coefficient means that the capacitance of the capacitor will increase or decrease with the increase or decrease in temperature. This makes the ECQ-B1122JF suitable for use in applications that require temperature stability.The ECQ-B1122JF also offers good tolerance against vibration and shock. This makes it a suitable choice for applications that require durability and a long service life. The ECQ-B1122JF is also capable of handling high frequencies, enabling it to be used in high-frequency applications such as television sets and other audio equipment.Overall, the ECQ-B1122JF is an efficient and reliable capacitor that offers excellent performance in a range of applications. Its thin dielectric layer allows it to store significant amounts of charge, while its temperature coefficient of capacitance ensures that it remains relatively stable. Its high tolerance to vibration and shock also makes it an excellent choice for applications that require long service life.
