The Vishay Dale WSR2R0400FEA is a high-performance Power Metal Strip® resistor designed for surface mount applications. It features a resistance value of 40 mOhms with a tight tolerance of ±1% and a power rating of 2W at 70°C.
Constructed with a solid metal nickel-chrome or manganese-copper alloy element, this resistor offers low TCR (< 20 ppm/°C) and very low inductance (0.5 nH to 5 nH), making it suitable for current sensing, voltage division, and pulse applications. It boasts excellent frequency response up to 50 MHz and low thermal EMF (< 3 μV/°C).
The WSR2R0400FEA is AEC-Q200 qualified and features sulfur resistance by construction. Its molded high-temperature encapsulation and all-welded construction ensure reliability in demanding environments. The resistor is housed in a 4527 J-Lead package, measuring 11.56mm x 6.98mm with a height of 2.54mm.
This component operates within a temperature range of -65°C to 275°C and is suitable for automotive applications due to its AEC-Q200 qualification. It is also moisture resistant and pulse withstanding.
