Film capacitors, also known as plastic-film capacitors, polyester capacitors, are electrical capacitors, which use polyester (PET) films as the dielectric material. These are capacitors whose construction is designed to have the characteristics of extremely low losses, excellent volumetric efficiency, wide temperature range and good self-healing properties for medium and high voltage applications. The MKT1820568016 film capacitor is a highly reliable film capacitor typified by its low equivalent series inductance (ESL). It features a very wide temperature range of -55°C to +125°C, high Ripple Current and rated voltage of 250V-450V which make it suitable for high voltage filter applications.

The construction of the MKT1820568016 film capacitor is composed of a winding of dielectric film, two small metal electrodes on both ends of the film to serve as contact surfaces, a heat shrinkable tubing for adjusting the width of the winding, adhesive tape for keeping the film in the winding slots and an epoxy top winding with a solid-plate electrode and an anode terminal. This construction makes the MKT1820568016 highly reliable in high voltage applications as it can withstand high voltage surges.

The working principle of the MKT1820568016 film capacitor is based on the dielectric properties of the polyester film used. The MKT1820568016 film capacitor has an insulation resistance of 8 Mohm@20°C/30V which allows it to store electrical charge. The dielectric film made from polyester shows good stability and charge retention, meaning that it can sustain a steady voltage charge without any leakage. This makes the MKT1820568016 highly reliable for high voltage applications.
