Polyester capacitors are electronic components used to store energy in electronic circuits or to meet the power requirements of power supplies. Capacitors are made with a coating between electrically conductive and non-conductive materials, with a dielectric material between the two electrodes.

Polyester capacitors are produced using polyester material and have a longer life and higher energy storage capacity than other capacitor types. In addition, they have a longer lifespan because they are less sensitive to temperature, humidity and other environmental conditions.

Polyester capacitors are used in a variety of electronic devices, especially power supplies. It is available in small sizes and various shapes and is available in various capacities.
