    Low ESR PSU Caps advice

    What would be the best low ESR capacitors to use in an LCD TV PSU? What would I be looking for in the datasheet as in ESR, impedance,frequency? Or can someone recommend some tried and tested reliable ones that I can just install, without having to worry about all the technical stuff?

    I myself use PANASONIC FM series from Digikey, you can also use FR series. Just match the value, voltage, dimension to the original. Use them for many, many, many years in lots of products (http://s807.photobucket.com/albums/yy352/budm/)

      Rubycon ZL_, Nichicon HD, and Chemi-con KZE can also be good options if you can't find a panny in a particular size.
      I love putting bad caps and flat batteries in fire and watching them explode!!

      No wonder it doesn't work! You installed the jumper wires backwards

        Re: Low ESR PSU Caps advice

        Thanks for the advice fellas but these are going to be used for the 2 main caps on a SMPS,I should have mentioned that before, is there a particular ohm rating I should be looking for,like some of them are 1.3 ohms,1.8 ohms ect...I want these to last a fair while.

          Try to get something with low impedance, as close as or below 1 ohm, but don't sacrifice lifetime rating (hours @ 105c) for lower ohms.

          The impedance is not that important for capacitors running at high voltage, in the mains section.

            Thanks mate,you've answered my question spot on.

              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...

              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,...

              Gigabyte GA-6OXT :: caps question
              by Foetuss
              Good evening

              I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
              Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

              But I was also suprised about the bigger boys, which are 330µF 25V.
              Could it be they used 25V caps because they were cheaper / available at that time?...
