What do you think is a good general-purpose low-cost versatile jellybean aluminum electrolytic capacitor line? I'm looking for a manufacturer and specific product line. When I say versatile, I mean available in a wide range of part values and operating voltages, and physical sizes.
Close - it's for a scatterplot of esr vs size for our new Chapter 1X capacitor-properties discussion. I've measured a mass of parts from our stock drawers plus some we've ordered for the purpose, and it's quite interesting to see what an extreme variation of performance can be seen.
I'd like to order a wide selection from one or two lines and be able to specifically mark them on the plot - obviously it'd be most useful if they're good parts to choose. For example, I used to get lots of Panasonic HFS series parts - reasonably-low esr, not too expensive, with a wide range of values and voltages available, but, it's been discontinued. I haven't yet chosen a replacement for our stocks.
Hey, can you guys include a small picture of a tantalum turning into a rocket? With that orange-greenish streak spewing out the bottom and maybe an impressive cloud?
We had one transformer, not too big, 10 pounds maybe, that ran warm and, if you teased the power switch, would make the wiring in the walls thump audibly at turnon. We measured close to 1000 amps peak current. It would also fry varnish at 130 volts.
Here's the transformer plot for Win...

This graph was really hard to shoot... terrible Moire' effects.
I've bought quite a few organic electrolyte parts for test, plus three values of OS-CONs we got as samples from their distributor, Capacitors Plus. But I wonder how hard they normally are to get in small quantities, since they aren't available from regular distributors?
Get the Mythbusters to blow up some electronics. It's a pretty sure thing to make tants go off, so it'd be a cinch to catch it on their highspeed. Now you just need a mythscuse to bring it up...hmm...

I would be interested in seeing some measurements on those audiophool / botique parts. Elna Cerafine, Black Gate, and a smattering of other types are "audiophile approved" electrolytics (if you can imagine such a thing). You could also explore the silly film caps (Auricap, etc.), but I don't mind that as much.
