Using FCA capacitors in audio circuits can result in lower sound distortion. The low ESR, the absence of piezoelectric
effects, and the non polar nature of the capacitor will eliminate sources of distortion in your audio circuits.

FCA surface mount film capacitors have advantages over tantalum and ceramic capacitors in PLL circuits. There
are no piezoelectric effects to create noise, they are not polarized, and they result in faster signal lock-up time.
