Film capacitors are a type of capacitor that has existed since the early 19th century. Generally, film capacitors use a polymer dielectric material that separates two electrodes. An electrical charge, either positive or negative, builds up on each side of the dielectric material. This electrical charge creates a potential difference in the capacitor, allowing electricity to flow through it.

ECQ-E1155JF is a film capacitor device made by Panasonic. This device is designed for energy storage, filtering, and signal coupling applications which require high capacitance range, low ESR, and high reliability. The ECQ-E1155JF features radial leads, banded end sealing, non-inductive construction, flame retardant packaging, and temperature-compensated capacitance. Furthermore, this capacitor is rated for an operating temperature of -25°C to +125°C and is available in a package size of 0201mm^2.

The working principle of ECQ-E1155JF is based on a parallel plate capacitor. When a voltage is applied, positive and negative charges build up on the two plates of the capacitor. As the voltage increases, the positive and negative charges increase, creating an electrostatic field inside the dielectric material. This electrostatic field creates an electrical field that acts to oppose further increases in the applied voltage, thus creating a capacitance. The capacitance of a film capacitor can be further increased by using multiple layers of dielectric material or by adding metallic surfaces on the outer sides of the capacitor to increase the area of charge accumulation.

In the ECQ-E1155JF film capacitor, the dielectric material is a polyethylene-naphthalate (PEN) film, and the metallic surfaces are formed by aluminum foil plates. The PEN film is chemically stable and has high dielectric strength and good mechanical strength. It also offers excellent high frequency resistance and low temperature characteristics. The aluminum foil has high electrical conductivity and good corrosion resistance, which makes it ideal for use in the manufacturing of film capacitors. The aluminum foil is also necessary for the reduction of dielectric losses at high frequencies.

The ECQ-E1155JF is well-suited for applications such as energy storage, filtering, and signal coupling. Its low ESR, high capacitance range, and high reliability make it an ideal component for filtering and signal coupling applications. Additionally, its temperature-compensated capacitance, flame retardant packaging, and non-inductive construction make it highly suitable for energy storage applications.

In summary, the ECQ-E1155JF is an excellent film capacitor device that is ideal for use in a variety of applications. Its parallel plate capacitor construction, with a PEN dielectric material and aluminum foil plates, gives it high capacitance range, low ESR, and high reliability. This capacitor is also rated for an operating temperature of -25°C to +125°C and has a package size of 0201mm^2. The ECQ-E1155JF is perfect for applications such as energy storage, filtering, and signal coupling, where it can be relied upon for excellent performance.
