Film capacitors (also referred to as plastic film capacitors, foil capacitors, insulation film capacitors, or film foil capacitors) are a type of capacitor made from a thin plastic film that is wrapped or rolled around an insulating material, such as glass fiber or ceramic. The plastic is usually polypropylene, polyethylene terephthalate, polyvinyl chloride, or polycarbonate. The capacitance of the capacitor is directly proportional to the thickness of the film and the distance between the conductive elements.

The ECW-U2104JC9 is a film capacitor designed for a wide variety of applications, such as high frequency, precision timing, and power conditioning. The ECW-U2104JC9 is made of a high-quality polyester film wrapped around an epoxy resin and glass-fiber encased sleeve. The capacitance is 100pF ± 20% and the voltage rating is 200V. It is RoHS compliant.

The ECW-U2104JC9 is most commonly used in AC line filter applications. It helps suppress both common mode and differential mode noise that may be induced in line voltage. It also improves the transient response of power supplies, thus improving the overall power quality of the system. In addition, the capacitor acts as a timing element in circuits such as oscillators, timers, and frequency dividers.

The working principle of the ECW-U2104JC9 is that when a voltage is applied across the terminals, the electric field near the boundaries of the insulator causes the current to flow freely across the electrode plates and through the polymer film. The current flow is linear and the voltage across the plates remains nearly constant. The amount of current allowed to pass through the capacitor is proportional to the capacitor\'s capacitance, which is determined by the size of the plates and the dielectric of the material used. The voltage across the capacitor is determined by the current passing through it and the amount of dielectric material in the capacitor.

The ECW-U2104JC9 film capacitor is a versatile component that can be used in many different applications. It is an ideal choice for high frequency applications such as AC line filter, power conditioning, as well as timing and frequency dividers. With its high voltage rating, it is also suitable for applications that require high voltage currents to be filtered. Moreover, its RoHS compliant design ensures that it meets the environmental regulations and can be safely used in all types of projects.
