INTRODUCTION
These are TO126 super precision power resistors.  They can achieve 1W in free air and 5W when attached to the
copper foil of a circuit board.  These models exhibit low noise, high frequency operation and high density installation.
Applications include:  Constant current sources, electronic load circuits, LSI tests, measurement, audio PA systems
and motor control.
