With industrial range (-40° to 85ºC) operating temperature flexibility, Transcend Industrial Grade temp DDR3L-1600 SO-DIMM memory modules are specially engineered to maintain optimum performance Even in extreme hot or cold environments. Additionally, the industrial Grade temp low voltage SO-DIMM modules operate at a nominal voltage of just 1.35V, presenting several advantages for systems in which they are use such as a lower electrical load on the memory controller and low power consumption.
