New space missions include more extreme requirements of storage and operational temperatures and vacuum conditions exceeding standard -55ºC / +125ºC conditions Miniaturization implies increase higher power dissipation and hence max junction and PCB temperatures.
This article describes the setup developments and some of the results obtained for the temperature characterization from -190ºC to more than +300ºC of passive components normally used for space missions, but with a standard operating temperature range in most of the cases. One...
