VCS301

300 Series Vishay Foil Resistors Bulk Metal® Foil Technology High Precision 4-Terminal Power Current Sensing Resistors with TCR as low as ± 1 ppm/°C and Tolerance ± 0.1 % FEATURES • Temperature Coefficient of Resistance (TCR): Any value at any tolerance available within resistance range The 300 Series offers precision Bulk Metal® Foil technology resistors as low as 5 mΩ with a temperature coefficient down to 1 ppm/°C and unmatched long term stability. The 4 terminal current sensing resistors, when mounted on a heat sink, can sustain 10 watts 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.
