Polystyrene capacitors have been long time favorite capacitor of audiophiles and high-end audio manufactures. Polystyrene Film capacitors are very highly regarded due to their most desirable electrical characteristics such as exceptionally high insulation, low leakage, low dielectric absorption, low distortion and excellent temperature stability.
However this type of capacitor is not limited to only audio applications, it’s perfect for any application that requires a through hole high tolerance capacitor. Polystyrene as a dielectric has many positive properties which include a low dielectric absorption, low distortion, low leakage, high insulation, and excellent temperature stability.
Polypropylene film capacitors boast a negative temperature coefficient of -150 ppm. They offer a low dielectric absorption of .02% and can handle temperatures up to a maximum of 105 degrees Celsius. If their negative temperature coefficient is not an issue, they make a good replacement for polystyrene.
We at Tedss.com pride ourselves on our vast selection of Polystyrene Film Capacitors. Polystyrene Film Capacitors can be found in communication/audio equipment such as guitar amplifiers, power amps, preamps and CATV amplifiers. Click here to browse our Axial Polystyrene Film Capacitor inventory.
Polystyrene capacitors are constructed like a coil inside, so they are not suitable for high-frequency applications. A note worth noting is that polystyrene capacitors exhibit a permanent change in value should they ever be exposed to temperatures much over 70°C; they do not return to their old value upon cooling.
Depending on the application, environment and specifications, there are viable – even better – alternatives for replacing polystyrene capacitors. Many customers have already successfully made the move. Contact Electrocube’s engineering department to discuss particular applications and find new solutions.
