300 Series
Vishay Foil Resistors
Bulk Metal® Foil Technology Precision Current Sensing Resistors
FEATURES
· Low Ohmic Value: to 0.005 · Temperature Coefficient of Resistance: 15ppm/°C at 0.005
Product may not be to scale
· Tolerance: to 5% @ 0.005 (See Table 1) · Power Rating: 10 Watts at 25°C on Heat Sink 3 Watts at + 25°C in Free Air (Further Derating Not Necessary) · Load Life: 0.05% R @ + 25°C, 2,000 Hrs., Rated Power · Isolated Heat Sink
The 300 Series offers precision Bulk Metal® Foil technology resistors as low as 5 milliohms with an extremely low 15 ppm/°C temperature coefficient 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% derating of the power specification associated with other technologies is not necessary. A choice of lead configurations is available.
