Flange Temperature ( )

Note:

(1) Insulating material is unnecessary between flange and resistors, flange and resistor is separated by alumina

substrate.

(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 1.3 K/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.
