  • Low thermal EMF (<3 uV/degC)
  • AEC-Q200 qualified for automotive applications
  • Anti-sulfur by construction

Applications

  • Current sensing in power converters
  • Motor drive current measurement
  • Battery current monitoring
  • Power supply load regulation
  • Automotive current sensing and protection

The WSL2010R1000FEA from Vishay Dale is a 100 mOhm Power Metal Strip current sense resistor in a 2010 surface-mount package. The all-welded solid metal alloy construction provides excellent stability and very low inductance for accurate high-frequency current measurement. The +/-1% tolerance and +/-75 ppm/degC TCR ensure measurement accuracy over temperature. AEC-Q200 qualified and inherently anti-sulfur, it is designed for demanding automotive and industrial current sensing applications.

The WSL2010R1000FEA operates as a current sense resistor where the voltage drop across the 100 mOhm resistance is proportional to the current (V = I x R). The solid metal alloy element provides stable resistance with low TCR. The all-welded construction between the resistive element and copper terminals eliminates contact resistance variability. Low inductance ensures accurate measurement at high frequencies, while low thermal EMF prevents DC offset errors in precision circuits.
