Is voltage coefficient not important in capacitors?

[safwatonline]

i was checking capacitors types and i noted that people always talk about the temperature coefficient however they never talk about voltage coefficient, is it negligible (for ceramic capacitors for instance)?

No, high dielectric constant ceramics have a considerable voltage coefficient. Consult manufacturers data sheets for details.

Thats an interesting question.Though I have not used discrete capacitors ever, I guess we need to consider the voltage coefficient of capacitors for them to behave linearly.Else we get in to the mess(challenge!) of Volterra series analysis .

Re: Capacitor

If analyzed carefully, capacitors are relatively complicated parts.
May be the attached paper can help a bit.
