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

Pb-free

Available

• 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)

RoHS*

COMPLIANT

• 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

• Lead (Pb)-free version is RoHS compliant
