division and pulse applications including
switching and linear power supplies, instruments
and power amplifiers
• Proprietary processing technique produces
extremely low resistance values (down to
0.001 Ω)
• All welded construction
• Solid metal Nickel-Chrome alloy resistive element with low
TCR (< 20 ppm/°C)
• Solderable terminations
• Low thermal EMF (< 3 µV/°C)
• Very low inductance, 0.5 nH to 5 nH
• Excellent frequency response to 50 MHz
• Compliant to RoHS directive 2002/95/EC
