The dielectric of polypropylene film capacitors is made of the thermoplastic, non-polar, organic and partially crystalline polymer material polypropylene (PP), trade name Treofan, belonging to the polyolefin family. They are manufactured as metallized wound and stacked versions, film/foil types. Polypropylene film is the most commonly used dielectric film in industrial and power capacitor types. The polypropylene film material absorbs less moisture than mylar and is therefore also suitable for "naked" gather designs without a fur coat. But the maximum temperature of 105 °C prevents the use of PP film in SMD packaging.
The temperature and frequency dependence of electrical parameters of polypropylene film capacitors is very low. Polypropylene film capacitors have a linear negative temperature coefficient of capacitance of ±2.5% over their temperature range. 1 Frequency determination circuit, filter, oscillator circuit, audio circuit and timer. They are also used to compensate induction coils in precision filter applications, and high frequency applications.
In addition to the application class qualification of PP film capacitors in the film/foil version, the standard IEC/EN 60384-13 specifies three "stability classes". These stability classes specify tolerances for temperature coefficients and allowable variations in capacity-defining tests. They are divided into different temperature coefficient classes (α), with associated tolerances and preferred values for the allowable change in capacitance after mechanical, environmental (humidity) and lifetime tests.
