The News:
Vishay Intertechnology announces a new surface-mount Power Metal Strip current sense resistor featuring a
Kelvin 4-terminal connection that reduces TCR and enables tight tolerances down to 0.1 % for increased
measurement accuracy. The Vishay Dale WSK1206 combines a tight tolerance of 0.1% and low TCR down to
35 ppm with extremely low resistance values down to 0.01 Ω in the compact 1206 case size.
 Reduces system errors while eliminating the need for system calibration
 Advanced construction incorporates a solid metal nickel-chrome or manganese-copper resistive element
with low TCR (< 20 ppm/ºC)
 A proprietary processing technique produces extremely low resistance values
