Tried the major mfgs and the typical datasheet looks like this:
Quote "Capacitance for X7S varies under the influence of electrical operating conditions such as voltage and frequency."
Then under diagrams ... nada, zip, zilch. Great.
One paper listed X7S with the same voltage coefficient as X7R but that doesn't sound right. Anyone have a link to some hard data, with a graph in there and preferably no marketing hype?
