Hello,
I would like to use the REF200AU and I notice the cold storage temperature maximum rating is -40degC. I have a need to be able store it at -50degC on occasion. Can you help me understand why the part is not already rated at -50degC for maximum cold temperature storage? Or let me know if the part rating can be updated to -50degC maximum cold storage? Lastly if there is a similar device with a greater maximum cold storage temperature can you let me know the part number?
Thanks,
HSG
