FEATURES

• Very high power to foot print size ratio (1 W in

1206 and 0.5 W in 0805 package)

• Ideal for all types of current sensing and pulse

applications including switching and linear power

supplies, instruments, power amplifiers and

shunts

• 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)

• Very low inductance 0.5 nH to 5 nH

• Excellent frequency response to 50 MHz

• Low thermal EMF (< 3 µV/°C)
