I've heard some people mention getting caps directly from Rubycon. I've emailed but heard nothing back. Anyone know how to go about ordering these? I don't use a lot but would be able to buy up to 5000 of them if I had to. Is this too little for them to deal with? Any other place where I might be able to get caps like this? Or does someone here sell them?

The size (10x16) has been difficult to find, and where I'm using them they can't be any taller than 20mm, I see Mouser now stocks the Nichicon HM cap like this, but I've been really happy with the Rubycon ones, and would like to...
