Can you clarify one thing for me: When I studied datasheets for these
it looked like they drop 50% of their capacitance at a DC voltage
of 10-20V.
Doesn't that make them a so-so bargain for power supply bulk capacitance ?
High dielectric "constant" comes at a high price performance wise. :)
You gain some, you loose some. Temperature performance and linearity.
It should not come as a surprise if you start to think about what
happens on the atomic/molecular level of dielectrics, it's a combination
of electrostatics and "mechanical" stress.
Cheers,
Magnus
