Are high Ripple Current caps okay for Power Supply's? I need to Replace 150uF 400v Cap, The one i can find available says High Ripple Current just wanna know if this is okay in general thanks!

Re: High Ripple Current Caps
What brand (e.g. Panasonic), series (e.g. FC) and diameter?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search. -
Re: High Ripple Current Caps
The higher the ripple current the better, as long as the ESR is close, but ESR is not very important for primary capacitors. But like tom asked, list the specs of the one you have and the one you are looking atComment

Re: High Ripple Current Caps
Hello. I want to first thank debom3 and tom66 for your help in fixing my samsung 52" lcd.
I have a question for tom66. I just bought a used toshiba 55g300u. when i went to buy it there were no issues. i haven't really used it much, but it just started making a high pitch sound and the picture comes on and off in no particular sequence.
i have tried to use the different hdmi and cable inputs and it happens to all. the picture goes on and off but i hear the sound. if i tap on the back cover the picture comes back or turns off. if you are on the menu and the picture goes off, you don't see the menu either.
i just need a general idea if the tv is toast, or if its an inverter, a bad backlight tube, power issue, or connection issue?
thanks again for your time! very much appreciated!Comment

I wish I had received my 55g300u in working shape. But for now I get to keep trying to fix it. I am learning a lot of new things though!Comment

I have a battery operated tab welder and the battery does not have enough current for the battery tab welder because after about 30 welded it does not have the same current output it voltage has gone down by at least 0.500 volts or maybe a more than that
I can fit 21700 battery cells in the enclosure it is very tight fit for four of them that are 35 amp high current capacity 35X4=140 high current output this should work a lot better than what is installed right now
I tested the battery cells there are installed right now and they are testing good with no issues that I... -
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... -
Howdy folks,
I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors. Because said caps are obsolete, they are pretty much impossible to find on the market; I did find a listing for some but I believe they are counterfeit. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. I am by no means an expert in electronics, and I've found a fair bit of conflicting information, so any guidance or confirmation would be greatly appreciated. While from a practical standpoint it's not worth... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

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...
