FEATURES
INTRODUCTION
The VCS331 and VCS332 offer precision Bulk Metal

Foil
technology resistors as low as 0.25
with a temperature
coefficient down to 1 ppm/°C maximum and unmatched long
term stability. The 4 terminal current sensing resistors, when
mounted on a heat sink, can sustain 10 W continuously
without an appreciable change in resistance (0.15 %
maximum). The typical 50 % power derating specification
associated with other technologies is not necessary. A
choice of lead configurations is available.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
