Thanks,
but actually the X5R capacitors I tried (like X7R but only -40..+85 temp range) are not specified according
to their leakage current. So I stick to bi-polar or non-polar electrolytic capacitors whose leakage current,
under a few 100s mVDC, remains reasonable, and whose dielectric absorption is low. leading to less
non-linear distorsion.
I found 4 second sources for SMT bi-polar electrolytic capacitors, and here are the manufacturers' links:
MVBP series at http://chemi-con.com/main/
NACEN at www.niccomp.com
UWP at www.nichicon.com
NEV at www.rubycon.com
my first source was at www.panasonic.com, "s-series", P/N ECEVxxxxxxxN (the final N for non-polar)
Hope it helps
