We have been approved by GB members, as well as others, whether we still have some regulator Mosfets left.

We bought 50 each (P & N), and only just managed to get 22 sets of 4 to cater for the subscription.
The remaining are quite a way out from the others. The Vgs spread is not small

So as much I would like to, I have no more to offer.
The rejects will be used for other test purposes for which matching is not required.

I encourage you to start a new GB of say 100 FETs or more.
That way your matching will improve with less rejects.
Also means more work, unfortunately.

Zhou Fang.

If you have enough quantities (100 pcs each) then Digikey also has them for comparable price.

Digikey has a long lead time: shipping in October ...
I have not been able to find better offerings so far
I am willing to get a GB going by ordering 2 x 100 Fets, but I need other volunteers ...
I am am in the process of almost completely rebuilding my "shack" at home so I cannot do any work there for some time

We have sent to Horio & ichiban as small packet registered today.

Disclaimer :
We cannot be held responsible for postal losses.
Happened to us twice in 2 years, both times with the USPS.
So the HK Post was not at fault.


Patrick

PS Fedex from HK to US is more expensive than the FETs.
