The UR is solid metl lloy construction tht cn withstnd significntly greter operting tempertures thn the conservtive model permits. The protective coting will operte up to 260 C nd the lloy cn withstnd in excess of 350 C. Therefore, the system therml design will be more signifi cnt design prmeter due to the het limittions of the solder joint.
