INTRODUCTION

The VCS201 and VCS202 offer resistance values as low as

5 mΩ and TCR’s as low as 10 ppm/°C typical with excellent

long term stability. The resistors are conformally coated. The

4 terminal current sensing resistors can sustain 2 W

continuously without an appreciable change in resistance

(0.5 % maximum).

The typical 50 % derating of the power

specification associated with other technologies is not

necessary.

Our application engineering department is available to

advise and to make recommendations. For non-standard

technical requirements and special applications, please
