    Yes in parallel. (-) to (-), (+) to (+).

    Same brand and series.

      Re: combine capacitors

      what is the application?
      general purpose yes.
      cpu vrm or power supply no.the esr will be different.

        Make sure that both units are the same manufacturer, series, capacitance, voltage and size. Two 1200uF units will equal 2400uF, which is slightly better.
        My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          will be lower than each cap separate.

          then again, it can be higher than esr of original cap, depending on the quality/mfr of original and of these 2 replacements...

          but 2 good quality caps will bring esr down in comparison to just one of same series...

            yes but the lowest esr cap will be subjected to excessive ripple current.this may shorten its life.

              After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
              by dragon3x
              Hi, I have some 32 bits computer motherboards that need repair, as they fail to
              power on.

              Here are some examples :

              (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
              switching supply area).
              (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
              than 6.3 V.)

              1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
              I replaced capacitors with aluminum-polymer.
              3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...

              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...

              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...

              Are there any datasheets available for Elna RJG capacitors?
              by Ady2017
              I have a 2007-era Panasonic VHS combo that is full of of Elna RJG capacitors. I am trying to test the capacitors to diagnose the machine and then select replacement capacitors but I can not find any datasheets for them. I did find a Elna catalogue from 2007-2008 but there is no mention of this capacitor series. Where these specially made for Panasonic and so not made available to the public? Any ideas what to find out what the ESR values should be without the datasheets? They are all between 10V and 50V and 47uF and 1800uF. None are leaking or bulged but I know that they need to be tested to be...

              Samsung UN70tu7000wxza no standby light, do I have bad capacitors?
              by ctroxtell
              I picked up a 70" Samsung UN70TU7000WXZA. The original owner said they were watching it when the power surged and knocked it out. I pulled the back off the TV and disconnected the main board from the power board, and the LED backlight came on, which I was told meant the power board was good. When everything is plugged in the standby light will not come on, looking at the main board BN94-17775A with a thermal imaging gun I can see one of the chips labeled 3202 is 251 degrees F just sitting idle. I found a replacement board, BN94-16115X; this board has the same symptoms, except it is a different...
