FEATURES
• 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
0.0003 Ω
• Specially selected and stabilized materials allow
for high power rating (to 10 W)
• All welded construction
• Solid metal iron-chrome or manganese-copper alloy
resistive element with low TCR (< 20 ppm/°C)
• Very low inductance 0.5 nH to 5 nH
• Excellent frequency response to 50 MHz
• Low thermal EMF (< 3 μV/°C)
• AEC-Q200 qualified available ⁽¹⁾
• Compliant to RoHS Directive 2002/95/EC
Note
