Film capacitors are non-polarized capacitors made from films of cellulose or plastic, where the two conductors are either applied onto the surface during manufacture or sandwiched in the layer. The ECW-H8273JL is a film capacitor designed primarily for high-voltage applications, built on a porcelain body with polyester film as the main insulation material between the electrodes. This capacitor is widely used in automotive, telecommunications and consumer electronics applications.

The capacitance of a film capacitor is determined by the area of overlap between its two electrodes, the thickness of the film between them, and the relative dielectric constant of the film. The ECW-H8273JL is designed for high-voltage, high-capacitance applications, with a maximum operating voltage ranging from 1000vdc to 6000vdc, and a maximum capacitance ranging from 5pF to 52pF. This makes the ECW-H8273JL suitable for a wide variety of electronic applications, including high-voltage DC motor drivers, flyback converters, snubber circuits, as well as motor run and start capacitors.

The ECW-H8273JL is designed to operate in any environment, with an IP67 rating meaning that it is dust-tight and can withstand the occasional submersion in fresh water for up to 30 minutes. This capacitor is also rated to operate up to temperatures of +105°C and up to altitudes of 5,000 meters. The ECW-H8273JL is designed to be used in automotive applications, such as engine control units, ignition systems, and ABS brakes, and in telecommunications applications, such as mobile phone repeaters, base stations, and RF cables.

The ECW-H8273JL is designed to be used with voltages greater than the rated voltage, up to the applied voltage of 10,000vdc. This means that this capacitor can be used to create a high-impedance DC path between two circuits that have different potentials. This can help protect sensitive parts of a circuit from static electricity, high voltage spikes, and other potentially hazardous phenomena. Additionally, the film capacitor can be used to filter out noise and ripple created by switching power supplies.

The ECW-H8273JL operates on an “open-circuit” principle, meaning that when no voltage is applied, the capacitor does not perform any function. When a voltage is applied, the electrical field across the film causes the alternate layers of metalized foil to build up electrical charge. The capacitance created by this process is determined by the area of the metalized film, the thickness of the film, and the relative dielectric constant of the film. The ECW-H8273JL is designed to provide reliable, consistent performance in extreme environments.

In conclusion, the ECW-H8273JL is a high-voltage, high-capacitance film capacitor designed primarily for high-voltage applications ranging from 1000vdc to 6000vdc. This capacitor is designed for use in extreme environments, and is ideal for automotive, telecommunications and consumer electronics applications. Its open-circuit principle allows it to provide reliable, consistent performance in a variety of high-voltage applications, including motor run and start capacitors, high-voltage DC motor drivers, flyback converters, and snubber circuits.
