Panasonic FC Dirt Cheap

[DreadPirate]

I found these (Panasonic FC 2200uF/50v) "by-polarized" on eBay $16/10 incl shipping, compare to $2.60 each at digikey. No one is counterfeiting these things are they?

They will counterfeit anything nowadays

My guess is they're either 1) surplus and just fine or 2) out of tolerance "seconds".

Cheers!

They certainly don't look like bipolar capacitors.

I wouldn't bother since some low ESR 2200uF, 50v capacitors are only $1.49 each at Mouser, or $1.25 each in quantities of 25 or more.

I thought it was amusing they say "by-polar", then clearly show the negative lead...

I have no way of confirming they are actually 2200uF, so I'll just have to take their word for it.

Hi,
if they do not know what product they are offering, then why should you "take their word for it"?

Ebay seller from China, what do I have to worry about?

Just wanted to report that I received my caps from lovelyleila2008 ebay vendor and they appear fine. Took 2 weeks. I've tested for esr, consistent .02 ohm, the weight is about right, so is the cap and bung. The color is a bit off, the FCs are typically a dark blue, these are black like some FMs I have. Included was the 50 count bag that Panasonic ships these in. My only issue is that they were packed in an envelope and are a little bit scuffed from rubbing other caps, but not too bad. A real bargain if you want FCs.

I buy a lot of Panasonic FC from digikey and they're all dark blue in color, so no reason for them to be black, if in doub you could ask the manufacturer.
Anyway it's dirt cheap usd1.58/pc plus free shipping

That particular place in China has been notorious for counterfaiting anything. Will never buy anything from there.

If you want to know what value your caps are, slap a 1K resistor in parallel with them, charge them up to 10 volts, then remove the voltage and measure how long it takes the capacitor charge to drop to 3.7 volts. Multiply that by 1000 and there are your microfarads.

If that's too fast, use a 10K resistor and multiply the time by 100. Math available on request.

speaking from experience... even local chinese in China are awary of the local companies they deal with. take ur chance.

Whadya make of these?

I can't find it in the Elna catalog. Do they have color schemes for special projects or OEM's. Is this a discontinued model? Any ideas? Thanking all in advance.

According to this panasonic link, different colors are a sign of possible counterfeit product. I'll see if I can get in touch with that panasonic group and see if they are interested in a sample. These look quite good, though, maybe even better than original! Tubeshunter on eBay also appears to have the exact same product, black 2200uF/50v with 32YV code on them.
