Plesa has arranged for shipping of all of EU parts.

The final list of names has 42 total names. So, there are officially 22 names for EU+UK. 50 pcs already are on the say to UK. 170 pcs ship to Plesa today.

Two shipments will post to Australia today.

10pcs will post to TiN today.

Asia is next on my list to contact for shipping addresses etc.

I have posted some results of measurements and behavior in Zlymex's original thread.

Received the 10 2DW233s yesterday in the mail.  Won't have time to play with them properly for a couple of weeks due to the upcoming holiday, but just wanted to say thanks to both VintageNut for doing the logistics as well as Zlymex for the gift.
Always learning. The greatest part of life is that there will always be more to learn.

Yes, thank you very much zlymex and VintageNut!
I got my envelope as well but may not have a chance to play with them properly until I get a noise tester, temperature controlled test box, and precision current source made up. Hopefully soon.

Well the factory order just arrived (at 0430 local time...) and I have packaged them and printed the international mail documents. Will send them later (0540 local time now and I really need to sleep.)

I have negotiated with the factory and they can supply as many as you can take. (Probably I am now one of their distributors targeting international market?) If you still want those but never made to this group buy please PM me.
I am new to the group and would like to buy 2. Is this the right place to ask?

Big thanks to Zlymex for his generosity and VintageNut for organizing distribution.

Just got my bag of candies too.
Too bad I'll be on local travel next couple days, but I might plonk few for quick checks tonight.  :-DMM
I guess I-V plot -15...+15V would be good starter?

Maximum current is 30mA and maximum power is 200mW. At 15V, you want to set current limit at 13 mA. Not sure if the part will draw more than 13mA at 15v.

The final envelope shipped today. All of the parts have been shipped. Most people should already have the parts delivered.

Hi,
The 2DW233 arrived today safely in Japan.

Thank you for your all the effort for the group buy.
It seems like only took 7days to arrive and there were no hassle with customs.
I have another parts to understand and play now. :)
