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
