Re: capacitors question
Digikey or Mouser are good sources for caps. The bulging ones need changed for sure and although the others look good they might be on their way out as well. Don't let it cycle anymore as you can damage other components.Comment

Re: capacitors question
Beware, there are several versions of 17PW26-4, so make sure to only order what's on YOUR board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: capacitors question
thank you,just looked on on ebay seller example ,470uf35V
10mm x 16mm x 5mm would they be the same ?Comment

Re: capacitors question
Do *NOT* order capacitors from eBay if you can avoid it. They are usually general purpose or cheap crap.
Get Panasonic FC/FM/FR from CPC. If you order more than £10 it's free delivery.
Be careful - Panasonic also sell "NHG" and "G" caps, these are not suitable. Only use FC, FM, or FR series.
By version - I mean there are several variants - may not just be v.1 but also different load variants so you need to check what's on your set's board.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: capacitors question
That will be fine although i'd buy from cpc or rs as they will both be cheaper than ebay. And also less likely to be fake.Comment

Re: capacitors question
There's no minimum order required for cpc or rs at the moment.Comment

Load variants,where how do i check ~?Comment

http://uk.rs-online.com/web/c/passiv...um-capacitors/ this site is slow.
Both have the option to filter by brand or product range. Select Panasonic on the rs site or FM FR on the cpc site (They seem to have stopped stocking FC).
You can then select by value/voltage and whichever size is closest.Comment

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... -
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... -
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... -
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... -
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...
