UCD3028: UCD3028RHAR

I confess I've never seen anything like that before.  I've got the question into our production and test folks.  They may have to try to do some digging back to 2014 when that SWR was issue, I just don't know.  I'll keep you posted.  

I haven't gotten any answer yet.  They are busy trying to figure out how to get more chips out.  I'll keep trying.  

Thanks Ian, do keep me posted. 

We're still looking at it.  It's kind of an archeology project with chips that old.  And since SWRs are primarily for internal use, that makes it more difficult as well.  

Could you please send the picture of the label without the red box on it?  It would be very helpful to see the lot number more clearly.  

Here goes. Total of 4 pics here.

There's 3 lot with SWRs. Sharing the one with TKY too.

Are the SWR lot subjected to the same test & quality standard and warranty terms as the TKY lot?

I'll check.  

Were still working on it.
