- summary and notes on the polystyrene capacitor or polystyrene capacitor detailing its properties, advantages and disadvantages.
Capacitor types includes:• Capacitor types overview • Uses and applications • Electrolytic capacitor • Ceramic capacitor • Tantalum capacitor • Polycarbonate capacitor • Silver mica capacitor • Glass dielectric capacitor • Polystyrene capacitor • Capacitor markings
Polystyrene capacitors are used within a limited number of applications. Polystyrene capacitor construction does not lend itself to surface mount technology and accordingly polystyrene capacitors tend to be used for leaded applications.
As a result of their construction and limited use, polystyrene capacitors are not widely sued these days and can be difficult to source.
Polystyrene capacitor properties
Polystyrene capacitors are not widely available these days, however they still find applications within audio circles. This is as a result of their electrical characteristics which lend them to these applications.
The polystyrene capacitors provide a number of electrical characteristics which make them suitable for a number of applications. These capacitors provide high insulation, low leakage, low dielectric absorption, low distortion and excellent temperature stability.
In view of their properties, polystyrene capacitors can often be used in place of silver mica or ceramic disc capacitors.
Polystyrene capacitor advantages and disadvantages
While the polystyrene capacitor has many advantages it also has a number of disadvantages as well.
