Voltage sensitivity of ceramic capacitors
Il se trouve que Brian Morrison a formulé :
Well known in SM caps with higher dielectrics, it's essentially a piezo-electric effect. Noticeable in PLL loop filters, a voltage transient on a tuning step can be considerably extended and in extreme cases will be microphonic. +1 AFAIK ceramic capacitors are never used in audio except for RF bypassing and in parralel with other types of capacitors. |
