    Oh those electrolytic SMD capacitors!!

    Why are these not up to good ESR levels according to my bob parker's ESR meter even new? Ditto on recent boards with these when I spot checked them.

    Is it not fresh or just very inferior? Is there much better one out there?

    Cheers, Wizard

      they tend to age rather quickly.
      they also have higher esr than radial lead parts of the same value.

          Don`t forget that lower capacitance caps does have higher ESR then bigger ones.

              Opinions/Advice on Do/Should I replace ALL Electrolytic Capacitors on old equipment?
              by RetroComputingGrotto
              I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.



              As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.


              What is your advice/opinion on whether or not on old(er)...

              Old electrolytic capacitors
              by alfredo2j90
              So as most of us know, old unused electrolytic capacitors are unrealiable due drying out and breakdown of the oxide layer.

              I have a few questions regarding these issues.

              1. Does using an electrolytic cap stop it from drying out or is it natural process that happens regardless?

              2. With the breakdown of the oxide layer the ESR will increase as well as DC leakage. Say the cap has remained unused on a motherboard, psu or games console for many years, if the cap does not physically pop when power is applied what other damage could occur to the system if it was...

              AA and AAA battery charger capacitors?
              by slybunda
              hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
              it has inside:
              2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
              2 x 470uf 16v LZ105c branded as G.Luxon

              not heard of these brands are they any good?

              iv attached photos of the charger and the board inside for an idea on the type of...

              Recapping Sony ICF-SW55 - verifying cap values
              by proxneo
              Dear reader

              I am performing a repair on a Sony ICF-SW55, which includes recapping (some) of the SMD capacitors on the mainboard. I am looking for verification of their values. At the moment, I'm 95% sure I've got the right values, but it is hard to find some official, credible or multiple independant sources on this.

              At the moment, I have selected replacements based on the following list of values:

              3 x 470uF 10VDC
              3 x 4.7uF 35VDC
              4 x 47uF 50VDC
              8 x 22uF 6.3 VDC
              1 x 220uF 6.3VDC
              5 x 100uF 6.3VDC

              Which...

              Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
              by sam_sam_sam
              I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

              This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

              After all of...
