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

0.001

Ω)

• 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

• Low thermal EMF (< 3 µV/°C)

• Lead (Pb)-free version is RoHS compliant

Notes

Ω derate linearly to 80 % rated power at 0.5 Ω

• Part Marking: Value, Tolerance: due to resistor size limitations some resistors will be marked with only the resistance value

* Pb containing terminations are not RoHS compliant, exemptions may apply
