Film Capacitors are electrical components consisting of two or more capacitor plates made of different materials separated by a thin film of dielectric material. ECQ-E6393RKF is a film capacitor designed to meet the ever-increasing demands of digital signal processing, power transmission and delivery, and communications technology. In this article, we\'ll explore the application field and working principle of the ECQ-E6393RKF.

Applications

The ECQ-E6393RKF is an ultra-low capacitance film capacitor with a maximum capacitance rating of 10nF. This makes it a great choice for a variety of applications, from high-speed data transmission to power conditioning. The ECQ-E6393RKF is particularly well-suited for AC and DC power supply, output stage circuits of switching power supplies, AC adapter applications, and many other applications where precise low-current rectification and filtering is required.

Working Principle

A film capacitor is a type of capacitor composed of two or more alternating layers of different types of materials. The materials are usually a thin film of conductive material such as aluminum or thin-film tantalum, sandwiched between two porous insulating dielectric layers. When a voltage is applied to the capacitor, a current will flow through the capacitor, creating an electric field, which creates a charge separation between the layers. The capacitance of the device can be adjusted by changing the thickness, or dielectric constant of the dielectric material. The capacitance of a film capacitor is also affected by temperature, which is why it is often used in temperature compensation circuits.

The ECQ-E6393RKF is a combination of several types of film capacitors. The dielectric material of the ECQ-E6393RKF is a combination of a thin-film aluminized polypropylene and a thick film of ABS plastic. This combination of materials allows for high capacitance, low ESR (equivalent series resistance) values, and stable performance in temperatures up to 85°C. The ECQ-E6393RKF also features an internal protective overcurrent element, allowing the capacitor to withstand high inrush currents and transient voltages.

The ECQ-E6393RKF is a well-suited choice for a variety of applications, due to its low capacitance, low ESR, and temperature stability. The combination of materials used in its construction make it a reliable choice for applications requiring precise low-current rectification and filtering of both AC and DC power supply, output stage circuits of switching power supplies, AC adapter applications and many others.
