For more information, please contact foil@vishaypg.com  For better performances, please contact application engineering INTRODUCTION The VCS301 and VCS302 offer precision resistors as low as 5 m with a temperature coefficient down to 3 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.
