Re: [TCML] Ebay I tems

Gates -
Thanks for clarifying the actual cost of the components in your eBay listing.
If no one makes a bid on your eBay auction, I'd just keep the board(s) and buy cheap IGBTs on eBay.
Suitable 1200v and 1000v TO-247 or TO-264 package IGBTs show up on eBay constantly for US$2.50-$4.00 each.
Watch the listings and prices carefully, because some of the sellers change prices weekly, or offer monthly "specials" at less that the usual cost.
Many different IGBT part numbers will work, just look for a 1200v (preferred) or 1,000v Vces rating, a pulse current rating of 200A or greater, and an integral freewheeling diode.

Herr Zapp

No problem my cost for the parts alone just the electronic components not including the IGBT'S was 80 dollars Canadian wich at the time would have been around 50 or less American.
I remember pricing the IGBT'S and the cost are you sitting down? 80 a piece with minimum order and all. my cost cant remember how many the minimum order was but they wanted $8,000 yes 8 thousand dollars wich was out of this world and way out of my budget at the time still is actuall,y lol anyway dint mean to upset you or anyone on the list just stating what my cost was that is all.
I did have all the corespondence with the seller at allied electronics but it's been so long cant remember where I put it. 

I will revise my listing not to confuse anyone.
I do still have all the pacakges that the components came in and when I have time will check and reprice all the parts. 

If I can find cheap IGBT'S for the boards I may even keep them.



Thanks

Hi Gates -

I think you may have misunderstood my question.
The cost of the bare SISG boards was $25; EXCLUDING the IGBTs, the cost for 
ALL the other components required to assemble a board was less than $23.
$23 plus $25 is $48, plus a few dollars for shipping, etc. Let's call it $55 
per board.

Your auction description states that "over $200 worth of components" are
included.
Since $55 is not equal to $200, it appears that something may be "missing". 

To restate my question, since the value of the parts described in the
auction does not appear to be $200, are you providing additional parts that 
are not listed in the auction description?

Or, is the "over $200" value in Hong Kong dollars, or some other currency
worth considerably less than US dollars?

(Not sure I understand your comment about "bursting my bubble"; please
clarify.)

Regards,
Herr Zapp





Your eBay

The IGBT'S at my cost was over 80 a piece that's why I did not buy them
sorry to break your bubble.
