# WSLP40261L000FEA (Component) ## Description 1 mOhms ±1% 7W Chip Resistor Nonstandard Anti-Sulfur, Automotive AEC-Q200, Current Sense, Pulse Withstanding Metal Element The WSLP40261L000FEA is a high-power Power Metal Strip® current sense resistor manufactured by Vishay Intertechnology, Inc. (Vishay Dale). It is a surface-mount, ultra-low resistance resistor designed for precision current measurement and power monitoring applications. The device features a 1 mΩ resistance value, ±1% tolerance, and 7 W power rating, making it suitable for high-current automotive, industrial, battery management, and power supply applications. The resistor uses a solid metal element construction with a 4-terminal Kelvin connection to improve measurement accuracy by minimizing parasitic resistance effects. It is AEC-Q200 qualified, making it suitable for demanding automotive environments requiring high reliability and stability. • High power to foot print size ratio • 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 0.0002 Ω • Sulfur resistance by construction that is unaffected by high sulfur environments • Specially selected and stabilized materials allow for high power rating (to 12 W) • 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 • Low thermal EMF (< 3 μV/°C) • AEC-Q200 qualified (1) • Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 #WSLP40261L000FEA #Vishay #CurrentSenseResistor #PowerMetalStrip #ShuntResistor #LowOhmResistor #AECQ200 #AutomotiveElectronics #BMS #PowerElectronics #SMDResistor #PrecisionMeasurement ## Component Details - **Owner:** adrian95 - **Created:** 6/22/2026 - **Last Updated:** 6/22/2026 - **Visibility:** Public - **Package or Case Code:** WSLP4026 - **Manufacturer Name:** Vishay Dale - **Mount:** Surface Mount - **Symbol Style:** parametric-v1 - **Manufacturer Part Number:** WSLP40261L000FEA - **License:** https://creativecommons.org/licenses/by/4.0/ - **Datasheet URL:** https://www.vishay.com/doc?30180 - **Part Type:** Resistor - **Used in:** 1 project ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
