Film capacitors are electrical components that use films of plastic-like material instead of typical metals as a dielectric. The skinny, flexible electrodes are held onto the film together with a tiny space, or “gap,” between them. This gap, along with the physical properties of the film material, determines the capacitance of the capacitor.ECQ-E2123KB film capacitors are a popular choice for many small and medium-sized electrical devices. Their small size, large capacitance range, high current capabilities, low ESR (equivalent series resistance) and low ESL (equivalent series inductance) make them great for applications ranging from precision timing to power conditioning, filtering, and more.The main advantage of ECQ-E2123KB film capacitors is that they provide high capacitance values in a very small package. This makes them highly suitable for applications where space is limited. Additionally, the capacitors offer low impedance and low ESR values, which are important in high-frequency applications.The capacitance of a film capacitor is determined by the gaps between the two electrodes, the dielectric constant of the film and the thickness of the film. ECQ-E2123KB film capacitors have an effective thickness of 0.033mm and a dielectric constant of 4.2, which makes them well suited for high capacitance applications.ECQ-E2123KB film capacitors are designed to be used in applications where high-frequency signals are present. The small size of these components makes them well suited for applications where space is an issue. Additionally, their low inductance and low equivalent series resistance (ESR) values make them great for applications where high performance is required.The working principle of a film capacitor is based on a simple electric field. When an AC voltage is applied across the electrodes, the current is considered a charge carrier, causing an electric field to be created between the two electrodes. This field results in a capacitance between the two electrodes, which is measured in units of farads.The ECQ-E2123KB film capacitors are commonly used in applications such as AC power control, AC power conditioning, filtering, and high-speed timing. They are also suitable for energy storage, pulse energy application, and switch mode power supply applications.In summary, ECQ-E2123KB film capacitors are a popular choice for many small and medium-sized electrical devices due to their small size, large capacitance range, high current capability, low ESR, and low ESL. Their low inductance and low ESR values make them ideal for applications where high performance is required. Furthermore, their effective thickness of 0.033mm and dielectric constant of 4.2 makes them suitable for high capacitance applications.
