Back Orders again!
The XTB-523 PCBs arrived a week ago, and the prototype has been providing the powerline interface for our home automation system (Ocelot) since then. I even unplugged the XTBR booster at the distribution panel, and have been using the repeater capability of the XTB-523. While the signals are not quite as strong, everything is still running fine.
The custom machined cases were shipped from Polycase Thursday, so I should be able to begin shipping the XTB-523 in a few days.
Last night I tried to order one of the critical components used in all my XTB transmitters, and found it was out of stock everywhere - Mouser, Digikey, Allied, Newark, Avnet, Future, and several other smaller companies. While I still have some inventory left that I can juggle based on demand for my products, I will run out before the backorder will be shipped - now scheduled for October.
Back orders were a serious problem a few years ago, but the distributor inventory has been pretty good recently. Now I’m seeing back order problems again, with some components even being special order only.
