    Vishay, Yageo - What are these capacitors like?

    They don't sell any of the rubbish brands as far as I know so I expect that these aren't too bad either.

    But does anyone have any experience with the quality of these? Or even what the are usually used in?

    Because I have never actually seen them in any piece of electronic equipment!

    Well your best friend is probably the spec sheet. Find out what capacitors it stacks up with in terms of ESR and ripple compared to the common capacitors that are recommended on these boards. Ones like the Panasonic FM and FC, Nichicon HE, Rubycon MBZ etc.

    I know Vishay are well known for producing semi-conductors like BJT's and MOSFET's and small IC chips. No idea about their caps thou.

      ESR I didn't look at but ripple is about a third of what the Panasonic of the same value can handle.

      According to the spec sheet, they are just general purpose capacitors, which would explain it.

      I don't think they even tell you the ESR. So probably not useful anyway, even if they are good quality.

        General Purpose capacitors have much lower ripple than equivalent low esr capacitors. And yes, ESR is not always shown in general purpose capacitor spec. sheets.

        In short, these capacitors are not good enough for use on most computer equipment. General purpose capacitors do have their uses (and these are probably good GP caps). However not so useful on say a motherboard.

          vishay make some of the best caps in the world, but not for low-esr high frequency usage.

          they make really good long-life high ripple stuff for Linear psu repair though.

            vishay also makes diodes and some semiconductor stuff (power stuff).

            Cheers, Wizard

              Yageo are teapo. Yageo is the world's largest producer of resistors, they bought teapo a while back.

                Being Teapo and owning Teapo are different, though...

                Maybe the quality of Teapo will improve under new management?

                Or maybe they can get Teapo to make their capacitors for them, for cheaper

                  They've owned them for quite some time. They definitely have teapo make their caps, vents are the same, series are the same, colors are the same, even the font is the same, just different names.

                  I think yageo is one of the major reasons of teapo's seemingly steady rise in quality, at least to me they are no longer "replace on site" in power supplies, but I've never seen them on a newer motherboard other than their poly's.

                    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...
