Not a quality issue, but a lifespan issue. Jan 14, 2012 · Hi. polycarbonate capacitors 3. Table 1 shows the relative permittivity of some common dielectric materials used in capacitors. Problem is, most polypropylene caps are way to big - like twice as big as a corresponding polyester cap. In general, ceramic capacitors are somewhat non-linear in their frequency and voltage responses, compared to film capacitors. Compare their construction, stability, voltage range, tolerance, and temperature performance to choose the right capacitor for your electronic circuits.

Polypropylene have somewhat better characteristics, they are superior in almost every aspect except that they are somewhat bigger and usually more expensive. Can anyone tell me if I should use poly caps rather than electrolytic and what the differences there may be in sound quality? May 25, 2023 · Film vs.
