MKT1820710065 Application Field and Working Principle

Film capacitors, originally developed in the early 1950s, are capacitors with a dielectric film of polypropylene, polyester or polycarbonate as the dielectric medium. This type of capacitor is a non-polarized capacitor consisting of a two-electrode system, separated by a thin dielectric layer. Through the use of this type of capacitor, it is possible to obtain a low inductance value and a low distributed capacitance in the wiring. With these advantages, the film capacitors of the MKT1820710065 series are widely used in audio frequency filters, pulse circuits, timing circuits, signal separation circuits, high stability power supply filters, and high definition as well as low signal noise.

The MKT1820710065 series film capacitor have several advantages over its counterparts. It is a non-polarized construction that requires no polarity for operation, and its dielectric capacitance is extremely stable over a large temperature range. The high frequency response range of the series is 10Hz to 100KHz and it can withstand rated voltage of 250V.

MKT1820710065 series capacitors consist of a polyester dielectric film as the dielectric medium, as well as two electrodes of polyester foil. The two electrodes are separated by a thin film which when formed in different thicknesses determined its capacitance. This makes it possible to manufacture capacitors in a very compact size while sustaining better performance. The construction of the capacitor also helps to minimize the dissipation factor and improve the insulation characteristics of the capacitor. In addition, this type of capacitor is highly durable and resistant to temperature, vibration and shock.

MKT1820710065 series film capacitors are manufactured through a series of processes. First, the film strip is cut from a polyester film with a specific thickness to serve as the dielectric. After this is accomplished, the film strip is placed between the two electrodes. An insulating and impregnating material is then applied to the film strip that helps to minimize moisture related issues and help to improve the insulation. Finally, the electrodes and impregnated dielectric film are spiral wound with a precise number and distance to form the capacitor.

The performance of MKT1820710065 series film capacitor is excellent due to the special dielectric material and the precise winding technique used in its construction. It offers high dielectric strength and film strength, as well as very low power loss, low noise and low temperature drifts. This type of capacitor is also resistant to oil, grease, moisture and other extreme environmental conditions and is ideal for use in high voltage circuits and high circuit density applications.
