Power Metal Strip® Resistors,
Low Value (down to 0.001 Ω), Surface Mount, 4-Terminal
FEATURES
• 4-Terminal design allows for 1 % tolerance
down to 0.001 Ω and 0.5 % tolerance down to
0.003 Ω
• Ideal for all types of precision 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
• Solderable terminations
• Solid metal nickel-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
• Compliant to RoHS Directive 2002/95/EC
