For instance, in the luggage compartment of a passenger plane this time of year? Does it get below 0C? Or is this question too open?
I just had a switching power supply fail when a demo unit got to a customer site. It was powered up soon after a long plane ride over the North Atlantic. The supply has an operational spec of 0-70C (storage -40 to +85). I'd expect it would be a bit out of spec if it started cold, but would the thermistors for the start up surge or something else get into problems at the cold temperature?
