Film Capacitors

Film capacitors are a type of capacitor that are used in electronic circuits in order to store electrical charge or signal a waveform. They are commonly used in a variety of applications such as power conditioning, power conversion, signal conditioning, sampling and timing. Film capacitors are typically formed by winding thin dielectric layers between two conductive plates.

MKT1817315406D application field and working principle

The MKT1817315406D is a film capacitor manufactured by Panasonic. It is a metallized polyester film capacitor with 4.7µF capacitance and rated voltage of 630V. This capacitor is usually used in AC/DC power supplies, EMI/RFI filter, motor start-up circuits, DC/AC converters and other DC circuits.

The working principle of a film capacitor is based on the electrostatic principle. It consists of two conducting plates, separated by a thin dielectric layer. When a voltage is applied across the plates, an electric field is generated. This electric field is responsible for the storage of electrical energy in the capacitor. When the voltage is removed, the electric field is dissipated and the stored energy is discharged.

The MKT1817315406D is a non-polarized type capacitor, meaning it can be used with AC voltages. It has an insulation resistance of 50000MΩ and a self-healing effect which enables it to heal itself in case of heavy DC load. Additionally, it can withstand higher insulation levels due to its metallized construction and low dissipation factor. It has a low equivalent series resistance (ESR) and high temperature stability.

The MKT1817315406D has proven to be an invaluable tool in the design and implementation of many electronic circuits. It is capable of providing consistent and stable power performance and is ideal for a variety of applications. It is also perfect for use in high temperature applications due to its high temperature stability.
