Overview of WSLT2010R3900FEB18

Key Features

  • All welded construction of the Power Metal Strip® resistors are ideal for all types of current sensing, voltage division and pulse applications
  • Proprietary processing technique produces extremely low resistance values
  • Sulfur resistance by construction that is unaffected by high sulfur environments
  • Specially selected and stabilized materials allow for high temperature derating (to +275 °C) and high power ratings (2 x standard WSL rating)
  • Solid metal nickel-chrome alloy resistive element with low TCR (< 20 ppm/°C)
  • Very low inductance (< 5 nH)
  • Low thermal EMF (< 3 µV/°C)
  • AEC-Q200 qualified (1)
  • This datasheet provides information about parts that are RoHS-compliant and / or parts that are non-RoHS-compliant. For example, parts with lead (Pb) terminations are not RoHS-compliant. Please see the information / tables in this datasheet for...
