(Down to 0.0005 Ω), Surface Mount

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 0.0005

Ω)

• All welded construction

• Solderable terminations

• Very low inductance 0.5 nH to 5 nH

• Excellent frequency response to 50 MHz

• Low thermal EMF (< 3 μV/°C)

• Solid metal nickel-chrome or manganese-copper

alloy resistive element with low TCR (< 20 ppm/°C)

• Material categorization: For definitions of compliance please

Note

Notes

• Part marking: Value; tolerance: Due to resistor size limitations some resistors will be marked with only the resistance value.

Ω derate linearly to 80 % rated power at 0.5 Ω.
