Film capacitors, whose full name is plastic film capacitors, are widely used in fields such as electronic equipment, electronic communication, precision measurement and audio equipment due to their many advantages, such as small size, large capacity, and high reliability. Taking MKT1813533015G as an example, we will explain its application field and working principle.

MKT1813533015G is a high-end series of film capacitors developed by KEMET. It adopts Japanese imported materials and high-precision automatic winding technology to ensure the performance of the product. It applies to occasions such as general AC and DC circuits, low-voltage circuits, filter circuits, and pulse circuits, and is especially suitable for circuit environments with high current, high vibration, and high temperature. For example, in the application fields of avionics, aerospace, scientific instruments, medical instruments, special lighting, automotive electronics, computer power supplies, and precision instruments, it can effectively improve product safety and reliability performance.

The MKT1813533015G film capacitor is composed of three parts: the wound core, the terminal weld joint (bead), and the outer casing. The winding core is a Mylar polyester film sheet and a special assembly technology throat shape. The upper and lower ends of the throat are tangentially extended into a rectangular shoulder shape, and the edge is made into a filter throat shape based on the wire shape size, to facilitate winding and improve core tension. The terminal weld joint is a bead-shaped lead end, which is welded to the winding core through special alloys. The outer shell is an anti-corrosive material that protects the body of the capacitor.

The working principle of the MKT1813533015G film capacitor is that under the action of a certain DC voltage, the two lead wires of the capacitor are connected to an external circuit, and the two electrodes of the winding core are in different polarities, respectively bonding Charging, when the two electrodes are charged to an electric state, the surface charges of the two charged electrodes repel each other, resulting in a large electric field between the two electrodes. At this time, the current in the external circuit is blocked, and the capacitor can be regarded as a closed switch. When the dc voltage disappears, the energy stored in the electric field is released. At this time, the current in the external circuit is restored, and the capacitance can be regarded as an open switch.

In summary, MKT1813533015G is a high-end series of film capacitors produced by KEMET. Products that use high-quality imported raw materials and precision winding technology are widely used in aerospace, military, and automotive electronics industries. The product has strong vibration and high temperature resistance, and its main function is to store energy in the electric field to form a closed switch, and release energy when the electric field disappears, to form an open switch.
