Film capacitors, also known as plastic film capacitors, polyester film capacitors (PET), polypropylene film capacitors (PP), polycarbonate film capacitors (PC), polyphenylene sulfide film capacitors (PPS), and other custom film capacitors are made with a variety of plastic films as their dielectric. Typically, a great selection of film capacitors are available in the market ranging from miniature to large, from general purpose to pulse operation, from low voltage to high voltage, from low-leakage current to low-ESR, from X2 to X1 safety standards. Among these capacitors, ECW-U1104JC9 slide film capacitor (ECW) manufactured by Eaton is one of the most outstanding products.

ECW-U1104JC9 is a single-angulated, polyester film-coated metallized capacitor that provides a high insulation resistance, a long useful life and a high voltage rating. It features a non-linear equidistance rating structure and an excellent dielectric constant. These capacitors have a rated operating temperature of -25℃ to 85℃ and a rated ripple current of 0.01A for 10kHz. They are available in a variety of package styles, such as surface-mount, through-hole, and axial or radial leaded packages. With a breakdown voltage of 3.1kV, ECW-U1104JC9 capacitors can withstand high-voltage surges and provide long-term stability.

The main applications of ECW-U1104JC9 capacitors include power supplies, communication and signal equipment, CCTV systems, appliances, automobiles, industrial monitoring systems and LED lighting. They are also used as output filters in DC-DC converters and in a variety of electrical circuits, such as low-noise audio amplifier circuits. Additionally, these capacitors are used as general purpose capacitors for bypass, decoupling and coupling. For instance, ECW-U1104JC9 capacitors are used to suppress motor noise in motors, provide low-leakage current bias circuits in audio systems, and reduce peak-to-peak output current ripple in power supplies.

In terms of working principle, ECW-U1104JC9 capacitors typically consist of two conducting surfaces separated by a dielectric material. The conducting surfaces are usually made from aluminum, copper, or any other conductive material, while the dielectric material consists of a plastic film that forms the main insulating layer. When a voltage is applied across the capacitor, an electric field is created across the dielectric material, causing a displacement of the conducting surfaces. This generates an electric charge on each of the two surfaces, thus creating an electric field within the capacitor and allowing current to flow through it. As a result, the magnitude of the electric charge stored in the capacitor depends on the capacitance of the dielectric material, which is determined by its thickness and dielectric constant.

In conclusion, ECW-U1104JC9 slide film capacitors are perfect for high-voltage applications, providing a reliable and efficient performance. Their non-linear equidistance rating structure ensures a voltage that remains constant over the course of their lifespan, and their wide range of package styles makes them suitable for a variety of applications. With a reliable dielectric material and excellent insulation resistance, this capacitor can be safely used in various types of electrical circuit, ensuring a long and trouble-free service life.
