Based on the type of dielectric used, metal film capacitors are either of polypropylene or of polyester type. This article covers the polyester metallic film capacitor which is also known as Polythene –Teraphthalate (PET) capacitor. These capacitors are highly heat resistant and can work at temperatures close to 150 °C.
The value of capacitors can be determined by several ways depending up on the type of capacitor like electrolytic, disc, film capacitors, etc. These methods include value or number printed on the body of the capacitor or color coding of the capacitor.
The polyester capacitor is designed with two metal plates where the polyester film is arranged between them; otherwise, a metalized film can be placed over the insulator. The polyester capacitor capacitance ranges from 1nF -15µF and works from 50 to 1500V. The tolerance ranges of the polyester capacitors are 5%, 10% & 20% and the polyester

Another popular type of capacitor is an electrolytic capacitor. It consists of an oxidized metal in a conducting paste. The main advantage of an electrolytic capacitor is its high capacitance relative to other common types of capacitors. For example, capacitance of one type of aluminum electrolytic capacitor can be as high as 1.0 F. However, you must be careful

Making a sufficiently accurate measurement of a different type of passive component, such as a capacitor, is an entirely different matter. This article describes various capacitance measurement techniques and compares the effectiveness of their accuracy.
Capacitance is measured under standard conditions to IEC 60068-1:2013. In case of doubt, stricter reference conditions are defined in sub-clause 5.2 of the same specification. Prior to being measured, a capacitor must be stored under measuring conditions until the entire capacitor has reached the measuring temperature and humidity.

Mullard (and Phillips) C280 polyester capacitors, with striped color codes, popular during 1960s/1970s. Before the introduction of plastic films, capacitors made by sandwiching a strip of wax-impregnated paper between strips of metal, and rolling the result into a cylinder–paper capacitors–were commonly used; their manufacture started in 1876, [17] and they were used

This is about the capacitors and their values finding as both number and color code.

The polyester capacitor is designed with two metal plates where the polyester film is arranged between them; otherwise, a metalized film can be placed over the insulator. The polyester capacitor capacitance ranges from 1nF -15µF and works from 50 to 1500V.
The temperature coefficient of the material is positive. Polyester capacitors are regarded as “general purpose capacitors”. They provide the best volume efficiency of all film capacitors at moderate cost and are preferably used for DC applications such as decoupling, blocking, bypassing and noise suppressions.
The tolerance ranges of the polyester capacitors are 5%, 10% & 20% and the polyester capacitor temperature coefficient is high. The isolation resistance of these capacitors is high, so these are the best choices for storage or coupling applications. These capacitors are extremely heat resistant so they can work close to 150 °C temperatures.
The polyester capacitor is also called polyester film and the dielectric material used in this is made with a polymer known as PET or polyethylene terephthalate. So this is the main reason to call this capacitor a PET Film Capacitor. As compared to other manufacturers, the leading manufacturer of this capacitor is “Hostaphan”.
There are several techniques to test a Capacitor to check its functioning. Some of the techniques include the following. In electronic produces, a polyester capacitor is a fundamental and essential component and polyester is used as the medium. The dielectric constant of type of capacitor is high, tiny in size has good stability & huge capacity.
