(6) Sound quality can be improved by using Film Capacitors
(6) No Shock Noise
When a printed circuit board is subjected to
mechanical shock, an MLCC X7R generates
Shock Noise due to Piezoelectric effect.
Film Capacitors do not exhibit this
undesirable phenomenon.

(7) No Buzz Noise
MLCC X7R sometimes generate Buzz when used
in AC circuit due to Piezoelectric effect.
Using Film Capacitors can be a solution to the
Buzz Noise problem.
