    General Capacitors to Stock...

    So I live in Alaska, and having things shipped to me each time I need them isn't exactly the most effective or economical way to do things. Instead I'd rather have some caps in stock just in case I need to replace a onesy twosy. I've often gotten systems in that use like 2 caps on the entire motherboard that are completely different from others and they are the ones that show the bulging signs. Replacing them often brings a board back from the dead.

    So I was curious if the veterans among you have a list of common capacitor sizes you recommend keeping around the shop that are often used on boards. I've noticed too that the diameter isn't nearly as important as some places make it out to be, i've never had issues with room (with the exception of this PSU i've been working on).

    My own personal note is that 6.3v/1000uF are very common, having a good 50+ of these probably wouldn't hurt. Any other sizes that are very common... say 10v/1500-1800uF?

    Id like to have enough of the right caps where I can not worry about having to order out for more but once in a blue moon.


    P.S...... also there are lots of brands on the badcaps.net store, I realize that they try to only carry high quality brands (i've used both Rubycon and Samxon) but for instance on the 6.3v/1000uF ones, there are about 10 different choices, some look to be identical short of their model "number". I'm assuming some of those are higher end with a longer expected life, any insight into which to choose? these are mostly used on motherboards, perhaps the occasional LCD....

    Thanks Guys

    In monitors, I see most of the times 470uf, 820uf, 1000 or 1200uF ... 25-35v (even though the psu is 5v or at best 12v)

    For computers, I would think 16v (for 12v coming into the boards) and 6.3/10v for 5v or lower areas would be the most common. 820 to 1500 seem to be common values for capacitors on motherboards.

    I've stocked on Panasonic FM/FR and Nichicon HM/HN.

            yeah i've seen a bunch of 1800 6.3's on input vrm, and a few 1500-1800 16v's too, but not as often, but...often enough

              Need some 16v caps for mobos.
              For screens it's best to go with 35v [works for both 25v and 35v].

              You also have to have some uF/volts combos in different diameters.

              If you don't work on the same thing all the time you could easily have 50 to 100 sizes stocked and -still- not have everything that comes up covered.
              [I know this because I stock that many sizes.]

              Not sure why you think you have a problem anyway.
              I've bought stuff from Alaska several times [5? 6? maybe] and it usually gets here in 4 days +/-1 via USPS. [Priority mail or not.]
              Shipping to Alaska takes about the same.

              Frankly, because of Customs, it takes much longer to get things to/from Canada than it does to/from Alaska.
