Subject: SMT non-polar electronic capacitors?

Hi,
For a very low frequency design I am in urgent need of a capacitor in the 10s of uF, with low leakage
current (considered with only a few 100s of mV DC accross) and above all non polarized. SMT non-polar electronic looks like the right technology. Panasonic
has good electrolytic ones but with 40wk delivery!!! I saw also that rubycon has some.
For this application, I tried ceramic chipc caps with X5R dielectric (10uF/10V), but they have 100s of nA leakage at high temperatures,
so I can't use them.
Anybody having seen a supplier for something like that?
Thanks,
Dominique
