To make an integrator, you don't want to use tantalum capacitors at all because you need capacitors with low dielectric absorption properties. I suggest that you look into polypropylene capacitors instead.
Some years ago, Bob Pease of National Semiconductor wrote a whole treatise about this. Polypropylene came in as pretty good from the dielectric absorption standpoint and capacitances in the range you require are easily available.
A reprint of his article might be available.
