FEATURES
• Molded high temperature encapsulation
• Ideal for all types of current sensing, voltage
division and pulse applications including
switching and linear power supplies,
instruments, power amplifiers
• Proprietary processing technique produces
extremely low resistance values (down to
0.001 Ω)
• All welded construction
• Solid metal Nickel-chrome or Manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
• Solderable terminations
• Very low inductance 0.5 nH to 5 nH
• Excellent frequency response to 50 MHz
• Low thermal EMF (< 3 µV/ °C)
• Lead (Pb)-free version is RoHS compliant
Note
1. The WSR3 requires a minimum of 1050 sq. mil. circuit traces connecting to the recommended solder pad
• Part Marking: DALE, Model, Value, Tolerance, Date Code
* Pb containing terminations are not RoHS compliant, exemptions may apply
