Film capacitors, also called polyester capacitors and polypropylene capacitors, are a type of capacitor that uses polypropylene or polyester film as its dielectric material. The ECW-FD2J395J is one such capacitor application field and working principle.

The ECW-FD2J395J is a polyester film capacitor. It has a small rectangular shape and a film thickness of 1.78 ± 0.03mm for the polyester material. The device offers a voltage rating of 400VAC or 1000 VDC and a capacitance of 0.002 µF to 0.22 µF. These capacitors are designed for use in stable AC power lines, AC motor controllers, and similar applications.

The basic working principle of the ECW-FD2J395J is that it stores electrical energy within its structure in the form of an electric field. The electric field is produced by the difference in voltage between the two terminal ends. When the voltage across the capacitor’s terminals increases, the capacitor charges up with electrical charge. When the voltage decreases, the capacitor will expel energy back into the circuit.

The capacitance of a film capacitor is determined by the size and shape of the film itself. The larger the area of the film and the lower the thickness, the higher the capacitance. The dielectric characteristics of the ECW-FD2J395J is determined by the thickness of the polyester film and the spacing between the interleaving layers of the film. This controls and optimizes the capacitor’s performance.

Furthermore, the capacitance of the ECW-FD2J395J is very stable over a wide temperature range. This makes it suitable for applications that require an environment with varying temperatures. A properly designed capacitor should be able to maintain its capacitance regardless of the temperature or humidity, making it perfect for use in motor control applications or in other similar applications.

The ECW-FD2J395J is a high quality film capacitor with excellent electrical characteristics. It offers a power rating of 0.2W and a maximum current rating of 750mA. It is designed for use in AC power lines, motor control, and many other applications. The stable performance and wide range of operational temperatures make it suitable for a variety of industrial and consumer applications.
