Wouldn't the simple answer be to offer the device and SD card as
separate items? Then on your site you say, "If you want to have storage
with the same industrial temperature range as the rest of my product
line then buy this card, or supply your own at your own risk."
Everybody selling fiber to the radio with an SFP slot does it that way.
I always buy their SFP module.

The reason I'm asking is that I'm in the process of developing up a
few new products.
To date, all of the packetflux products are designed with components
rated -40 to +85C (I.E way cold to way hot). I'd like to retain this
rating, but I'm running into a minor snag:
For storage, I'm planning on integrating a SD card (probably microSD)
in a socket. I only need a GB or so, and SD card memory is
inexpensive at that range.
Unfortunately, all the reasonably priced SD cards are only rated down
to about -25C or -13F. which are about ~$3 in qty. "Industrial
temperature range" ones which are good down to -40C/F are available
but they add at least $30 to the cost for non-name brand, and even
more for known brands. When you're talking about a $100 end-user
price, a $30 1GB SD card seems excessive - and probably isn't even
possible if I want to meet the $100 price with some margin.
So, I'm currently playing the 'what options do I have' game. I hate
to ship a product only rated down to -25C/-13F, but I know for at
least a large chunk of my customer base they never see below this
temperature, especially when you add a watt of power dissipation in
the case with the device. Which leads me back to my original
question: What's the lowest temperature most people would expect to
see inside their enclosures.
