(2) At surface mount soldering, temperature profile in Flange shall not exceed 220C. (3) Using heat conduction 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 155C in operation. (5) 0.1% tolerance resistors and over 220ohm resistance are available, please call factory. Lead Free DB LECTRO Inc. 3600 boul.
