Features and Applications 
Small 20Watt high power resistor in TO-126 package with 5.9 C/W heat resistance from hot spot to 
flange. 
Non-Inductive, fit for high speed SW power sources, high precision CRT and high-speed pulse 
handling circuits. 
Thin style in small package suits high density installation of electronic instruments. 
Superior vibration durability with heat sink mounting. 
Complete thermal flow design available. 
Color video amplifier of CRTs, emitter resistors of power SW circuits, snubber circuits, VHF amplifiers, 
load resistor of pulse generators.
Between flange and resistor are insulated.
