Re: ENERMAX Liberty ELT500AWT

I think I have clearly stated I want D10, right

There is plenty of D12,5 caps everywhere, but D10, thats the deal

Re: ENERMAX Liberty ELT500AWT

If you're interested, I can mail you some NCC KZE 3300uF/16v (12.5x35) ...

I should still have about 20 pcs in my box of parts from my last Digikey order. That would be about 3-4 months ago, but I keep all my capacitors in sealed plastic bags, in a box, normal temperature and all that, so no need to worry about their condition.

1.15$ a piece, about 3$ in postage and packaging.

I also had some Panasonic FM but last time I only ordered about 10 pcs so now I should have about 4-5 pcs left, and the price I bought them at sucks, about $1.5 each.

Anyway, with both of these you have to pay attention at the diameter (they're 12.5 in diameter, some if not most power supplies only reserve 10mm in diameter for these capacitors)

Re: ENERMAX Liberty ELT500AWT

Just had a chat on Digi-Key. They didn't helped me much, but…well, if I will succeed in getting part number for any of the caps I want, I may get them order it from manufacturer

So, here is the deal. I don't know as you, but I would be interested in 3300 uF 10 V/16 V D10 caaps of these lines: NCC KY, Panasonic FC, Nichicon HE or Rubycon YXG/YXH. I will try to contact the manufacturers directly and get some infos from them…

Re: ENERMAX Liberty ELT500AWT

I have seen enough Teapo fail to consider them mediocre, at best. I would not use them for a re-cap, but would probably keep existing Teapos.

Re: ENERMAX Liberty ELT500AWT

Teapo…how can you even say that? U on BAD_CAPS here

[mockingbird]

Re: ENERMAX Liberty ELT500AWT

Try to get 10mm Teapo SC instead... I rarely see the larger value ones bloat though admittedly I haven't the means to actually test them. I have FSP PSUs out in the field with them that are still alive and kicking after many years.

Re: ENERMAX Liberty ELT500AWT

I'm glad I bought some quantity from him back then. You're right, $2 a piece after shipping from this guy, but 4 is more than eough for this PSU.

I am idiot. I jsut realized it was 0,6 EUROcents Capking has Samxons for 0,9 USD, that's not bad actually but I need some for 16 V too, he has for 10 V only.

Re: ENERMAX Liberty ELT500AWT

The leads of most capacitors are up to about 1-1.5mm in diameter (I see for example in a datasheet 0.05" which I think is 1.27mm)

You should be fine with some heatshrink tube with the internal diameter up to about 3-4 mm. May need larger if you want to use it for example on power supply wires diameters.

What to buy... it all depends on the shrink ratio, most are 2:1 or 3:1 ...if the capacitor has leads that are 1.25mm (0.05") and you buy 2.5mm tube with a 2:1 ratio, there may still be some room between tube and leads.
If it's 3:1 ratio, the tube will be really shrinked around the lead

When I last ordered tube for me, I bought these two because I was too lazy to do the math and get the perfect fit:

http://uk.farnell.com/jsp/search/pro...sp?SKU=1190979

http://uk.farnell.com/jsp/search/pro...sp?SKU=1190935

The black one is too thin for atx psu cables but just right for capacitor leads.. after shrinking you'd still be able to pull it off the leads, but otherwise it stays in place.

The green one is quite large even for power supply wires but when shrunk it's quite ok for wires.

Re: ENERMAX Liberty ELT500AWT

I think the wire is less than 1 mm so something under 2 mm should be fine. Can't say exactly, I have only plastic caliper which is useless for such small things

[mockingbird]

Re: ENERMAX Liberty ELT500AWT

Ah, you're going to use one piece of wide heatshrink for both leads? I was refering to the individual leads, as I have seen it on other caps... Reason I ask is I want to order an assortment of shrink tube but I'm not sure exacty which diameters are commonly used for various applications. Up till now I have been "bodging" with the black tape.

[Behemot]

Re: ENERMAX Liberty ELT500AWT

Digi-key states mounting holes distance for caps, have a look

[mockingbird]

Re: ENERMAX Liberty ELT500AWT

Do you know what diameter of shrink tube are suitable for cap leads?

Re: ENERMAX Liberty ELT500AWT

I took some too, but I have run out of everything. I'd take from this guy if he could provide some reasonable price for say 100 pcs/16 V and 130 pcs/10 V.



Usually it works fine with bigger cap before and smaller after, but there definitelly should be some capacitance on both sides of the coil…

I personally have no problem with China, most of interesting stuff comes from there anyway They make everything there so they can sometimes get it and sell individually for good money

Actually, the more I look at this board, I think I can just go with a fatter cap, if I raise it up. I seem to have 50mm of clearance and then some before it hits the fan. I would of course shift it over to where the wiring is and insulate the leads with heatshrink so it doesn't come in contact with coils surrounding it.

SO what would I need panny FR? I would like to use Nichi HE because of how cheap they are on digi key.

So I need two caps anyways. Damn I was about to ask if using single 6800uf FC cap would be acceptable, but now after you explain it, it's not going to work.

Looks like I'm going to fleabay.

EDIT: even worst it's coming from china.

Re: ENERMAX Liberty ELT500AWT

I'd say there are genuine, just expensive.

What jumper man, it's pi coil. Filtering cap before, filtering cap after. Than there are two shunts for OPP on both +12V rails.

Oh so that's what they are called, pulse induction. Sorry I'm not knowledge about these yet.

Re: ENERMAX Liberty ELT500AWT

Last time I took from Joe for aprox. 60 cents a piece.

Well my 10v ones have two different sizes, one is 10x30 and other is 10x35, I have no idea, but if that sheet is correct 13x21, 820 and 1010 for 16v I should be ok with rubycon PX, but I'm wrong right?

No, PX is grossly underspec'd for this application, I would not use them.

Re: ENERMAX Liberty ELT500AWT

Yes, RS is definitely OK as a replacement:

Here's a guy selling them:
http://www.ebay.com/itm/120957531897

KEep in mind the bunge of these particular caps will have those concentric rings. They're authentic, but they have that style of bunge because this was an experimental series from Samxon.

Well my 10v ones have two different sizes, one is 10x30 and other is 10x35, I have no idea, but if that sheet is correct 13x21, 820 and 1010 for 16v I should be ok with rubycon PX, but I'm wrong right?

Yeah I found him too but the price is terrible. Last time I took from Joe for aprox. 60 cents a piece. I would not take anything over 1 USD including shipping.

Yeah, I'm scare of fakes, I would buy them if I had no other choice.

Anyways, this is what I'm working with.

black = ground
yellow = 12v rail
red = caps
purple = wrapped copper jumper wire on top.

As far as I can tell they are parallel.
