Anyone know where to get any cheap electrolytic caps above 35V (anywhere
from 35V to 200V)? (used as power supply filtering)

http://www.jdr.com/

Seems to be the cheapest I have found and I'm thinking about ording a load
of them (about 50$) but I figured I surely can buy in bulk at a cheaper price?

Does 'ripple current' or ESR mean anything to you ? Graham C #### Chris Jan 1, 1970 0 Anyone know where to get any cheap electrolytic caps above 35V (anywhere from 35V to 200V)?

Hi, Jon. The cheapest electronics components are usually available
from places like JDR because they've been bought from parts brokers.
These resellers get parts that have been returned from customers for
one reason or another.

Usually, parts are returned because the project didn't pan out or
volume wasn't what was expected (good for you!), but it can also mean
other things. Parts can be returned because incoming QC found them to
be deficient in one way or another. They may have been stored
improperly. They may also have been sitting on a shelf somewhere for

Graham has a point. When you're buying from a "hobbyist" or "surplus"
outlet, you are taking a chance, and you really should take that into
account. Miseries with caps can be particularly tough to
troubleshoot.

Given that, you might want to look at some of the surplus suppliers on
the Arrick Robotics Surplus Electronics Parts List page:

http://www.robotics.com/surplus.html

If one of those sources has what you want, you'll definitely be able
to beat the price of JDR Microdevices.

Cheers
Chris
