    Results of changing uF rating?

    I am having a very hard time finding any 3900uF low ESR caps, at least in quantities less than 1000, which I need 4.
    What will be the result of recapping with some 4700uF ones I can get? Or recapping with some 3300uF ones I can get?
    These are in the VRM section powering the AMD Socket A, running 1400Mhz. This is on Soyo K7ADA motherboard

      I've done that same exact thing until I found some 3900uf. Works fine.

              Sorry, of course using the 4700uf, not the 3300uf. Nichicon HE from Mouser also.

                  If you're in the US or Canada, I can get you some 4700uF Rubycons. I replace 3900uF caps with 4700uF caps all the time, never had an issue.

                      I'm confused,
                      I found 3 different lines in the digikey catalog that were 3900 6.3 12.5od low esr. Nichicon, United Chemicon, and panasonic.

                          Primarily, I prefer to use the E3 series (10, 22, 47), although I also prefer using the E6 series (10, 15, 22, 33, 47, 68) as well.
                          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.

                              Is it no harm to replace with capacitor without ripple current rating?
                              by chth96
                              When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


                              Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
                              But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
                              Rubycon YK DataSheet (b...

                              Cyberpower 1500AVR UPS repair
                              by quickname
                              I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

                              Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

                              I decided to verify that the batteries were...

                              Hello folks,
                              New to Audio equipment - I got this receiver, I connected speakers and I tried to connect to Bluetooth. My phone would not see the receiver (Receiver flashes the BT as if it's trying to pair). Then I put it on FM radio, I get white noise on the speakers. I click the +/- Tuner button, and it moves from saved station 1 through 28, but the frequency is 87.x MHz not changing. At this point, thinking I may need to do a FW upgrade, I connected an HDMI cable to the TV and TV reports "No Signal" - TV "Kind of" sees the receiver (When connected to greyed out port,...

                              Each GPU reballing produces different MATS results, looking for root cause ?
                              by DynaxSC
                              Hi,

                              I have an Nvidia card which makes me wondering, what is the root cause for Mats errors. The story is as follows:

                              1. When I received the card Mats showed one memory with errors.

                              2. Replaced the memory chip, but no change, still same error, so memory chip is ruled out.

                              3. Made a carefull reballing of the GPU, MATS showed 3 memories with errors, the one before, and 2 other new chips.

                              4. Made a second reballing of the GPU and Mats shows again only one memory chip with errors, the same on as in the beginning.

                              5. Made...

                              Lenovo V310-15ISK - It doesn't work after changing the battery
                              by pabloroggeri
                              Good guys. I changed the battery to a Lenovo V310-15ISK.

                              The laptop worked perfectly, I changed the L15C4A02 battery because it didn't last very long.
                              When I connected the new battery, the charging LED stopped lighting up and the one next to the charging pin also did not react when I pressed the power button. Minutes before changing the battery it worked perfectly and stopped working after putting the new one in. Even if you put the oroginal battery in or connect it without the battery, no LED lights up when you press the power button nor does it give an image, nor does the...
