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

    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

    Why do you want cheap ones ? They may be rubbish ! Does 'ripple current' or ESR
    mean anything to you ?

    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
    20 years. Bad for you.

    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

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

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