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)

• Compliant to RoHS directive 2002/95/EC
