Film Capacitors

Film capacitors play an essential role in many modern electronic circuits. Film capacitors are capacitors whose dielectric layers are made of polymer films, such as polystyrene, polyester and polypropylene. These capacitors are usually small, lightweight and can handle high voltages and temperatures. Film capacitors are widely used because of their excellent high frequency response, high dielectric breakdown strength, low dissipation factor, high impact resistance, excellent temperature stability, wide operating temperature range and long life.

The ECW-F6134JLB is an ultra-thin polyester film capacitor and is one such application field of capacitors. It is a non-polarized capacitor with a rated voltage of 630V, an insulation resistance of 100M ohms, and a maximum operating temperature of + 105°C. It is designed for applications where high insulation resistance and high stability are required.

The ECW-F6134JLB is constructed with two electrodes covered with an ultra-thin polyester film. The silicon rubber encases the capacitor, providing moisture protection and insulation. The capacitor is electrically connected to two printed wiring boards, which in turn, are connected to the external circuit. The electrodes are plated with nickel to improve the solderability. Additionally, to ensure Xylene insulating properties, the capacitor is impregnated with acrylic or epoxy resin.

The working principle of the ECW-F6134JLB is quite straightforward. The electrodes and the dielectric layer together create an electric field. This electric field can store electrical charge. When a voltage is applied to the capacitor, electric charges are drawn from one electrode to the other, creating an AC electric field. The capacitance value of the capacitor is determined by the size of the dielectric layer and the magnetic field between the electrodes.

The ECW-F6134JLB is a high-performance and reliable film capacitor. It is often used in a variety of applications, such as audio, automotive, communication, and lighting systems. It can also be used in power supply, voltage amplification, and signal processing systems. With its high performance, excellent insulation, and low temperature stability, it is ideal for use in demanding applications.
