wilykat - That's called "Derating a Cap" where if you put in a higher voltage into a cap, it's supposed run at a higher capacitance. Where this theory this came from it's not true, I never seen it work and I've been working with electronics since 1969. But that example you posted is an extreme within its own classification!

Uniserver - Since you have said in past posts (about Power Supplies cap) that you find the Nichicon Caps leak in every case, I stay away from them. I buy my parts from Newark/Element 14 or DigiKey. I noticed that Mouser's prices have gone up on a lot of things, not just in the caps. But I do need to go to Mouser for specific Caps that the others do not carry or only sell in Bulk - like the 2200µf cap in the SI Power Supply, Newark/Element 14 only sells them  in a "roll of 500" @ $1.30 a cap! I only need 2 caps and I don't have $600 to buy 500 of them!
