Fast Rise Time - These resistors are available in a

low reactance design for fast rise time and extended

frequency response.

High Stability - These resistors are available in a

High Stability version with maximum resistance

change of ±20ppm/year under normal conditions.

Wide TCR Range - These resistors are available in

Low and High TC configurations from -20ppm/K to

+6000ppm/K.
