Polyester film caps are good for coupling and storage purposes. They often find use in audio and oscillator circuits and moderately high frequency circuits. Capacitance values range from 0.001 µF to 10 µF. Voltage ratings range from 50 V to 600 V.
One common type of film capacitor is the polyester film capacitor, also known as the Mylar capacitor. Since polyester film provides the best insulation and durability, it is employed in its construction as the dielectric material. Polyester film capacitors are tiny, cheap, and have low dielectric losses.
Film capacitors are used in electromagnetic interference (EMI) suppression and as safety capacitors (Classes X and Y). While ceramic capacitors offer better dv/dt capabilities, film capacitors are good (with a maximum value of 2200 V/µs) making them suited for use in snubber circuits.
Film capacitors are made out of two pieces of plastic film covered with metallic electrodes, wound into a cylindrical shaped winding, with terminals attached, and then encapsulated. In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:

Polyester capacitors are available in the range of 1nF to 15µF, and with working voltages from 50V to 1500V. They come with the tolerance ranges of 5%, 10%, and 20%. They have a high temperature coefficient. They have high isolation resistance, so they are good choice capacitors for coupling and/or storage applications.
Tolerance The tolerance of many kinds of polyester film capacitors simply has 5% or 10%, so that is adequate for several applications, however. At present, capacitors with better tolerances are available at a low cost. Operating Temperature
Figure 2: 0.1 µF polyester film capacitors Polycarbonate film capacitors are a reliable alternative to polystyrene, excelling in critical coupling and timing applications. They exhibit linearity within a limited temperature range of 25 to 85 degrees Celsius and their temperature stability is lower compared to polystyrene film capacitors.
A polyester capacitor with a high temperature will dissipate huge power, so this feature will make the capacitor inappropriate for the applications of high current & frequency. In addition, polyester material shows a major change in capacitance up to 5% when the temperature comes close to high or low-temperature limits.
In comparison, polypropylene metallized film capacitors and double-sided metallized film capacitors have a self-healing property, and they are suitable for use in low pulse and medium pulse applications.
