Overview of WSK25125L000FEA

5 mOhms ±1% 1W Chip Resistor 2512 (6432 Metric) Anti-Sulfur, Automotive AEC-Q200, Current Sense, Pulse Withstanding Metal Element

Key Features

  • 4-terminal design allows for 1 % tolerance down to 0.0005 Ω and 0.5 % tolerance down to 0.001 Ω
  • 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 (down to 0.0005 Ω)
  • Sulfur resistance by construction that is unaffected by high sulfur environments
  • Solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 ppm/°C)
  • Very low inductance 0.5 nH to 5 nH
  • 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...
