Vishay Foil Resistors

Bulk Metal

Foil Technology High Precision 4-Terminal Power

Current Sensing Resistors with TCR as low as ± 1 ppm/°C Maximum,

Tolerance ± 0.1 % and Rise Time 1.0 ns Effectively No Ringing

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
