    Bi-polar capacitors

    Haven't been able to find any discussion on these (although momaka has proven my searching skills are lacking).

    Few years ago lightning struck real close to the house, the lights dimmed and the only casualty was the router (Linksys wrtsl54gs). Well, capacitors and soldering were scary and I had no clue how these things worked. So with a lot of time, but not a lot of knowledge, I learned about bi-polar or non polarized capacitors and soldered one of those in with the same farad value (I knew at least that much).

    Pic related it is the router that has been working since.

    Re: Bi-polar capacitors

    A bipolar cap is basically two polarized electros back to back (leads of the same polarity in series). You can hack one like that if you don't have a real bipolar on hand, just keep in mind that two caps of the same value in series = half the capacitance.

      Neat, I might try and cut that thing open

        I would have thought that there would be two 470uF caps in there to make up for that
        I love putting bad caps and flat batteries in fire and watching them explode!!

          Why does my ISP router hate my "homemade" power supply??
          by double_DD
          Hi all,

          It's gonna be a long intro, so please buckle in, as it's a problem that's been bugging me for several days now. Thanks in advance.

          So, I have 2 modems/routers, whatever the proper nomenclature is, one from ISP and one mine. I want to power them via USB-C rather then their original mains adapters (for reasons, that are hard to explain to sane people). Both routers come with 12V/3A mains adapters.
          For this purpose I acquired USB-C charger with 250W and 5 ports, 2 of which can supply max 20V/3A. Since 12V isn't a standard PD voltage option (and to future proof,...

          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...
