    Caps dimensions

    Hi guys,
    recently I bought 2200 uF 25V and 16V caps. I didn't pay attention on the dimension when ordering and I noticed that 25V caps have much bigger diameter than 16V. I can see that there are completely the same rated caps (capacitance, voltage, temperature) but different sizes (length, diammeter).
    I know that the biggest advantage of the smaller ones is the space they occupy on the PCB. I wonder if bigger size caps (same parameters) have longer life span? What is their advantage?

    Re: Caps dimensions

    please read the datasheet about working hours.4
    Within the same series, often a larger diameter means more operating hours

      Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!
      by momaka
      I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

      For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

      It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

      Heathkit IO-4205 Power Supply Caps
      by eryjus
      Hello,

      First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

      I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

      I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

      Identifying caps on an old Zoom 9000
      by Paxman_Swede
      Hello!

      I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

      The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

      I have studied the board and...

      HannStar Hanns-G HC194d LCD monitor repair
      by momaka
      Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

      Help with switching power supply caps
      by captain150
      I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
      I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
