(2) at surface mount soldering, temperat ure profile in flange shall not exceed 220c. (3) at screw mounting, using heat conducti on grease on surface of flange is recommended. (4) heat resistance between resistor and flange is 3.3 c/w. heat design will be done, as resistor temperature shall be under 155 deg c in operation. (5) 0.1% tolerance 5ppm tcr resistors and over 220ohm resistance are available, please call factory. (6) please note, terminal material is tin plat ed copper, but inside of resistor contains pb- a g high melting solder that is exempted by rohs directive 2002/95/ec.
