Film capacitors, also known as plastic film capacitors and film dielectric capacitors, are electronic components used to store electrical energy in an electric field. They are constructed of thin plastic films, typically polyester, polypropylene, polycarbonate, and Teflon, which are then rolled up or wound into an insulated cylinder. Inside the cylinder is an electrical conductor, usually either copper or silver, which is wound around a cylindrical core or pole piece. This core is typically made of a high-dielectric, electrically insulating material. Film capacitors can be used for both DC and AC applications and are used in a variety of power electronic circuits such as: resistors, filters, switches, inductors, and motor controllers.

The MKT1818422065G is a film capacitor that is used in a wide range of applications. It is a 100Vdc, 39µF capacitor with a capacitance tolerance of ± 10%. It has a rated temperature range from -25°C to +85°C and a ripple current up to 9.3mA. The MKT1818422065G is mainly used as an alternative for large electrolytic capacitors and other ceramic type capacitors. It can be used in AC and DC circuits, power supply systems, high frequency switching circuits, and smoothing circuits. It is also suitable for noise suppression and high frequency filtering applications.

The working principle of film capacitors is based on the same basic principles as other capacitive components. The size and shape of the conductor will determine its ability to store and discharge an electric charge. The construction of these capacitors begins with a highly durable, electrically insulating film material. This material is typically rolled up or wound into an insulated cylinder or pole piece. Inside the cylinder is an electrical conductor, usually either copper or silver, which is wound around a cylindrical core. This core is typically made of a high-dielectric, electrically insulating material. When a voltage is applied across the terminals of the capacitor, electric charge is stored at the interface between the conductors and the insulating film. As the voltage changes, the field within the capacitor will cause the charge to move and the capacitor to discharge its stored electrical energy.

The MKT1818422065G is a popular choice for many power electronic applications due to its high capacitance, low equivalent series resistance (ESR), low internal losses, and wide temperature range. It is also well-suited for power supply systems, high frequency switching circuits, and smoothing circuits, as well as noise suppression and high frequency filtering applications. With its long life and high reliability, this film capacitor is an excellent choice for a variety of circuit designs.
