ESR value for this cap
Im trying to test some capacitors, but I cant find any chart with the value for 450 volts
this is the one that Im need the ESR 220uf 450v
Thanks...

Re: ESR value for this cap
Is there meant to be a picture with this post - we would need to know the
manufacturer and series of the cap although I believe that high voltage caps
do not have the esr stated as they are considered general purpose.
What was the outcome in this thread can you update.

Re: ESR value for this cap
Yep,without knowing the brand and the series, we cannot tell.

Re: ESR value for this cap
Thank you....
Actually is because of that thread that I'm asking, I had to move, so I put the TV on stand by, now I'm working on it again.
I started testing the ESR of the caps, because just by looking all look fine.
but I cant find a chart for the value for 220uf 450v
Any way the reading that im getting is different in all three, so I'm going to replace them, and see what happens.

Re: ESR value for this cap
It's not unusual for cap mfrs not to specify an ESR or impedance for higher voltage caps. OTOH, they do usually specify a ripple current rating. If you're replacing, 105C parts (or even 85C parts in a reasonable environment) from one of the three "Cons" or Panasonic should be safe choices. Just go for same value, voltage, lead spacing and package size (a few mm shorter is usuaally OK).PeteS in CA

anyone heard of these caps before? at first glance i mistook them to be Elna caps but closer look and it was elite. not sure if they are known failure prone brand.
also they are 47uf and 450v. why are they so large in height? i can get replacement 450v 47uf caps that are a quarter the height. what am i missing here?
if i were to replace them what should i be looking for?
they are on the power board of a toshiba (vestel) tv power board.

Unfortunately I got rid of most of my power supplies a few years back so I hunted some on eBay. Of course I could have got some with already good caps but what's the fun in that when you can save unsuspecting victims on eBay from buying something that could cause them problems?
I'm also aware that Solytech is capable of making a decent unit, minus their caps. This one is on the 80 Plus website as being able to do its full wattage.
I bought two of these as a lot. One was made in July 2017 and one was made in September 2017. Interestingly, the only... -
hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue
recently I was handed a family members old NAD C320BEE that they had in their loft for storage for a few years but when powered on it went into power safety mode due to a problem on the protection circuit somewhere before it went into storage I was told it worked fine I found lots of people online talking about how the capasitors are known to be pretty bad in this model and can cause this issue the only problem being I don't have much experience sorting... -
Hi guys
Does anyone have a chart (pdf. whatever) that shows the power sequence for all the common series of AMD and Nvidea GPUs? Or maybe a chart for each manufacturer?
Something like this I have for RX400-500 series (see attached). This looks to be a segment from a document that possibly had all the different GPU families
I put this in this forum section as it is not s schematic request though it is kinda related
TIA
