    35v 470uf replacement help...

    Still learning here. Can replace caps easily and get them to work but still learning the id process.
    I have a ltec 35v 470uf 10x20mm cap and am not sure what I can replace them with that is close enough to work, anything sold here?
    Forgive me if I sound stupid but still learning about the specs on caps.
    I know you can increase the voltage on a replacement but not sure on the uf rating? Or any other rating?
    Thanks!

          What leads you to suspect the cap is bad?

          Need the brand and series info off the cap and what it's being used in.
          Series is usually a 2 or 3 letter code near the temperature line, but not always.

          If in doubt, list the info on the cap here, line by line.

          Then you'll need to find the datasheet on the cap, if it exists. You look up the cap and get the manufacturers supplied values. Then we can figure out what available brand and series would be best used to replace it with.

              These caps are swollen on top and are from a power supply out of a flat screen tv.
              The specs are:
              35v
              470uf
              LZG series
              Man:Ltec
              10mm x 20mm

              Having a hard time finding an exact replacement that I am sure will work.
              Great link posted above about explaining things but still a bit confused.
              Sorry!

                  Re: 35v 470uf replacement help...

                  First, look up the specification for Ltec LZG series:



                  In that chart, find the capacitor in question. You will find that 35V 470uF has the following ratings:

                  Ripple: 1400 mA
                  Impedance: 0.046 ohms @ 100Hz
                  Size: 10x20mm

                  Your replacement needs to have the same or more ripple, the same or less impedance, and it needs to fit.

                  Samxon GT is sold by badcaps.net and is an exact match for ripple, impedance, and size:
                  https://www.badcaps.net/store/produc...roducts_id=114

                  Other options include Nichicon HE, and UCC KY:
                  http://search.digikey.com/scripts/Dk...me=493-1582-ND
                  http://search.digikey.com/scripts/Dk...me=565-1576-ND

                  Any of these would make a great replacement.

                          Yuo should replace all of the caps, not just the ones that are swollen. Just because they're not swollen, it doesn't mean they have not failed, or at the least are not impending failures.

                              Good advice! I will do just that.
                              The other caps on this board are:
                              Ltec LZG series
                              6.3v
                              1000uf
                              8mm x 16mm
                              ripple= 850
                              impedance=.086

                              Trying to find a match here @ badcaps but where do you find the impedance spec for the caps sold here? Am I missing something?

                                  For the purpose of finding replacement caps, you can consider impedance and ESR the same thing...

                                  Badcaps does not have an exact match for that one.

                                  Closest match, should work fine, as it exceeds the ratings of the original:
                                  https://www.badcaps.net/store/produc...products_id=70

                                  If you want an exact match:
                                  http://search.digikey.com/scripts/Dk...me=565-1486-ND
                                  (840 vs. 850 ripple, but ~1% difference is close enough to "the same" in this case)

                                              What model/brand TV? There are members here with information that could help. It's not always about the caps in the PSU. Some have known problems that can be pointed out by members that regularly work on them or have done so in the past.

                                              It is always best to post as much information as possible in the beginning of a thread. Make/model/size/age/problem description/what you have done. It's easier to toss out the unnecessary info than it is to keep coming back trying to get more details from you.

                                              Picture walking into an auto parts store to get a starter for your car. The counter man starts with some basic questions. Make/model/year/2 or 4 door/engine size, etc. Questions are not for his amusement, but to zero in on the correct part for your vehicle.

                                              Cheers and Welcome!

                                                  by Agent24
                                                  I have acquired a used Dick Smith Q-1760 power supply - although the OEM is Manson Industrial
                                                  It has at least one problem.

                                                  The voltage control potentiometer VR2, 50K is faulty - going high resistance / open circuit in the CCW end and leading to the output voltage jumping around.
                                                  I have already ordered a replacement potentiometer, so that's not an issue.

                                                  Now, I want to replace all three electrolytics on the PCB as they are CapXon and I don't trust them so much, I will replace them with something better while I've got the thing apart anyway.
                                                  All are CapXon...

                                                  by reformatt
                                                  Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

                                                  It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

                                                  Is it no harm to replace with capacitor without ripple current rating?

                                                  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.

                                                  Unknown transformer : how to find a good replacement part ?

                                                  Hello guys,

                                                  I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

                                                  I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

                                                  PS4 controller left stick potentiometer replacement issue

                                                  Hello,

                                                  Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

                                                  So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

                                                  I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...
