Film capacitors are a component that can store a certain amount of electric charge and are used in electronic circuits. ECQ-E1273KF is a kind of radial film capacitor, a non-polarized one, and its application field is mainly for intermediate frequency circuits and AC bypass and shading circuits. With its superior properties such as relatively low ESR and volumetric efficiency as well as its good performance under high frequency and temperature, it is widely used within a full range of applications in machines, computers, radio and television, meters, instrument and other industries.

Film capacitors are usually made of different types of film, including metalized plastic film, paper film, polyester film, polypropylene film, etc. The metalized film capacitors are usually used in the intermediate frequency circuits and AC bypass and shading circuits, and their main structure include plastic film, metal electrode, metal foil and dielectric. ECQ-E1273KF is made of metalized polyester film, which is produced through metalization technology and ED process, so that the inner surface of the polyester film can be covered by metalized glue. As a result, the film capacitor has the advantage of low dissipation factor, high capacitance stability, capable of withstanding high temperature and so on.

The working principle of ECQ-E1273KF is based on the same principle of electrical condenser. This kind of film capacitor is formed by applying a metallized film to the inner layer of a paper dielectric in an alternating stacked sheet between the metalized foils. When the power source is connected to the items, a DC current will travel through the circuit, it will cause the electrode to make a gradual charge buildup between opposite electrodes and build an electric field. When the power supply is shut off, the accumulated charge on the film capacitor can be stored and can greatly reduce the voltage drop on the circuits.

The capacitance value of the ECQ-E1273KF can be adjusted by varying the number of foils used in the winding process. When assembled and connected together, the electrical properties of the film capacitor will be maintained above the specified value within the specified temperature range. In addition, the ECQ-E1273KF is designed to operate at low frequencies and has a long operating life. It adopts a long-term reliability design, which allows it to operate in a high humidity environment.

Overall, ECQ-E1273KF is a successful application of metallized film capacitors due to its superior performance and long service life. It can be used in a wide range of applications in machines, computers, radio and television, meters, and other electrical instruments. With its reliable performance and high stability, it can effectively reduce the impact of intermediate frequency circuits and AC bypass and shading circuits and ensure the stability of the electric network.
