Film Capacitors

Film capacitors, also known as film dielectric capacitors, are electrical components that store electric energy within a thin film, installed between two conductive plates of metal foil. This type of capacitor is a non-polarized device and is often used with alternating current circuits, due to its high linearity, low noise and low leakage current. The MKP385475125JPI2T0 is an example of a film capacitor, and its application field and working principle are presented in this article. The MKP385475125JPI2T0 is one of the most common types of film capacitors, as it is a high-voltage polymer film capacitor that is ideal for various applications, such as medical, measurement and instrumentation, communication, and in consumer electronics. Being a non-polarized device, it requires no special orientation or direction. This capacitor also has a high reliability, due to its low leakage current and small temperature coefficient. The MKP385475125JPI2T0 is composed of two aluminium electrodes which are assembled in a double-layer design, enabling it to handle up to two times the rated voltage. The electrodes are insulated with a polypropylene film which is protected by a non-woven fabric on its exterior. This combination ensures that the buildup of electrostatic charge is avoided. Additionally, the device is resistant to heat, dust, moisture and pollutants which may be encountered along its path of operation. The working principle of the MKP385475125JPI2T0 is based on the capacitance effect that is generated between the electrodes. The capacitance is the electrical property which determines the amount of charge stored by the device in the form of energy. When a DC voltage is applied to the device, the charge carriers (electrons) move in one direction, while the other oppositely charged carriers moves in the opposite direction, thus creating an electric field. This electric field creates a charge separation between the electrodes, which in turn reduces the current flow across the device. The charge stored on the capacitor also acts as a counter current to the current flow of the circuit, and its value is determined by the applied voltage. In conclusion, the MKP385475125JPI2T0 is a film capacitor which is ideal for applications such as medical, measurement and instrumentation, communication, and consumer electronics. Its high-voltage design, low leakage current and low temperature coefficient make it reliable and suitable for operation in harsh environments. Its working principle is based on the capacitance effect which is generated between the electrodes when a DC voltage is applied, allowing the device to store electric energy in the form of charge.
