Page 2 of this PDF on Mouser lists the 3.9uF cap I mention, with one rated at 250V. I simply cannot pull it up on the Mouser site by part number. But since it is in a catalog listed by Mouser, you have every right to ask them to sell it to you. And if they don't, I still feel this cap is so good it's worth using DigiKey just to purchase it. Indeed, you may make your money back if you buy 10 or so and then present them to users here. Sell the extras (for a reasonable price, of course), and you will make back your shipping and could be a benefit some users here (some of whom live outside the United States). But of course, that would require you to be willing to box and ship them like trag does.
