Film capacitors, also known as film dielectric capacitors, are electrical components made from dielectric films such as polyester, polycarbonate and polypropylene. They are generally constructed by applying an adherend and an electrode on the dielectric film, which is then wound in a spiral or folded into multiple layers. Film capacitors are known for their high capacitance per unit volume, long lifetime and stability, excellent noise filtering and transient response, good insulation resistance and low capacitance change with applied voltage.

ECQ-E2563JFB is a surface mounted, high voltage, Class Y1 film capacitor developed for highly reliable aerospace, military and commercial applications. It features a robust construction in a small ceramic package for easy mounting on PC boards. It is compliant with MIL-PRF-55681 specifications, and has an insulation system of 1.20mcd•m (minimum). With a maximum rated voltage of 2000Volts and low ESR, it is excellent for filtering and transient power supply applications.

When used in an application, the ECQ-E2563JFB provides an almost constant capacitance over a wide frequency range. This has been achieved by using a combination of high dielectric constant and the multiple-layer film winding technique. The capacitor also provides a low ESR over a wide temperature range and low inductance, making it suitable for high frequency applications. As the capacitor is rated for 2000Volts, it can be used for a range of switching and voltage regulation applications.

The working principle of the ECQ-E2563JFB film capacitor is simply that, like other capacitors, it stores electric charge between two electrodes. When a voltage is applied to the two electrodes, one of the electrodes, known as the plate, becomes positively charged. The second plate, known as the dielectric, becomes negatively charged. This creates an electric field between the two plates, which stores energy and increases the capacitance of the capacitor.

The film layer acts as the dielectric, and it is this layer that provides the dielectric constant, which is the measure of the ability of the film to store energy. The film capacitor also has a low ESR, which is a measure of the resistance to current flow through the capacitor. This allows the capacitor to efficiently store energy, and the energy is released quickly when needed. The smaller size of the ECQ-E2563JFB also makes it a valuable component in miniaturized circuit designs.

In conclusion, the ECQ-E2563JFB film capacitor is a reliable, high voltage capacitor that is suitable for a range of applications, from power supply and switch mode circuits to high frequency applications. Its small size and high dielectric constant make it an excellent choice for space constrained designs, and its low ESR ensures efficient storage of energy and fast discharge when required.
