Film Capacitors A film capacitor, also known as a plastic capacitor, is a capacitor that uses thin plastic film as a dielectric, usually a polyethylene terephthalate (PET) film. Film capacitors can offer improved performance and extended temperature range due to their low dielectric absorption.In the electronics industry, film capacitors are used in various applications such as power electronics, high-voltage power supply, signal processing, and as shields in high-frequency noise suppression circuits. The most common types of film capacitors are metalized polyester, polypropylene, polystyrene, paper and film, and foil.The QYX2A474JTP1FG is a film capacitor specifically designed for high-frequency switching power supply applications. It is made of non-metallized polyester, which offers excellent performance in temperature environments from -40 to +105°C. The capacitor also has a wide range of input voltages from 250V to 400V. It features a low ESR and a high operating temperature of up to 125°C.The working principle of the QYX2A474JTP1FG is similar to that of other film capacitors. It features two metallic plates with a non-metallic material, such as polyester, in between. The non-metallic material acts as a dielectric, allowing the capacitor to store an electric charge. When an alternating current passes through the capacitor, the electric field between the plates is changed, which causes the voltage across the capacitor to fluctuate. This fluctuation is related to the frequency of the alternating current and is the basis of the capacitor’s functioning.The film capacitor’s capacitance and ESR values depend on its construction. The dielectric material, the thickness of the dielectric layers, and the surface area of the plates all affect the capacitor’s performance. A thicker dielectric layer allows the capacitor to store more charge, but it also increases the ESR value. The surface area of the plates also affects the ESR value and the maximum current that can be carried by the capacitor.The QYX2A474JTP1FG is designed for high-frequency switching power supply applications, and is suitable for DC to DC converters, voltage regulators, and switching power supplies. It is also suitable for medical devices, automotive applications, and telecommunications. It can handle high ripple currents and offers high performance in high-frequency switching environments. Its low ESR, high temperature range, and wide voltage range make it an ideal choice for these types of applications.
