Title: The poison of counterfeits.....
Post by: level42 on February 01, 2015, 09:16:28 PM: I've bought electronics from China now and then, and often quite successful.......however....you have to be careful.

Here's an example....

I was looking to get one or two LM138/338 voltage regulators.I checked my local electronics shop and they cost €11,95 a piece: http://www.deradiobeurs.nl/zoeken/articledetail/100060070/

Of course I checked Ebay and found some very very much cheaper one's:
http://www.ebay.com/itm/2pcs-LM338K-LM338-5A-Adjustable-Voltage-Regulator-NS-1-2V-To-32V-/191332338051?pt=LH_DefaultDomain_2&hash=item2c8c4bc983
$2.58 for TWO AND free shipping.......mmmmmm....

I had my suspision and looked at the markings...the logo on top is of National Semiconductor.
But how to know if they are real ?

Then...I did some googling and found this video and was flabbergasted....

I had heard about counterfeits which at least still _try_ to act like the real thing (but very often fail) but this......unbelievable....

"When something looks too good to be true, it probably is"

Andre, Radiobeurs is actually very expensive. There are cheaper (web) stores in Holland that sell these stuff

The problem is often shipping costs/time. I like having the option of driving to a store and pick up something I need -now-. And having to pay a bit extra for that service (keeping a store open, having stock, paying personnel) I don't mind.

And honestly, they are not THAT crazy expensive. I actually bought a good part of their MPSU transistors because else I will have to get them from the US.....no-one here has them anymore and the prices was GREAT:) (meaning a LOT cheaper than the U.S. price even without shipping.

Here's another nice trick I came across on badcaps.net by the way.....

Post by: level42 on February 04, 2015, 07:27:39 AM: LOL :)

Amazing isn't it. The funny thing is that they used Rubicon caps....which are great quality....but of course it won't have the mentioned capacity on the outer shell....

That's why I love my ESR meter.....that would catch this :)

And that cap is even more nasty....risk of fire :?

Post by: anunaki on February 04, 2015, 09:10:41 AM: This particular component costs 8,17 EU here http://www.eijlander.nl/LM338K-Spanningsregelaar-1.2v-38v-5a-To3-a-391739-2969.html

Of course it's pretty cool you can go to a local shop and get your stuff right when you need it. We have Elektronica709 in Spijkenisse, Rick is also selling components

Did you see the picture ? That is EXACTLY the same one as I found on eBay which is probably fake :)

Oh and:
De verzendkosten bij vooruitbetaling zijn EUR 7,50 excl. BTW.

Post by: anunaki on February 04, 2015, 09:18:00 AM: This looks like a pretty legit business, with a store in Ede

but they can get scammed too I guess

edit: of course shipping like that kills small deals like this
