Power Metal Strip^®Resistors, Improved Stability

(0.25 % and 0.5 %), Low Value, Surface Mount

FEATURES

• Current sensing in high-temperature (+ 125 °C)

applications

• Greater stability with maximum resistance

change of 0.25 % or 0.5 % through 2000 h

workload

• Ideal for all types of current sensing, voltage

division and pulse applications including

switching

and

linear

power

supplies,

instruments, power amplifiers and shunts

• Proprietary processing technique produces

extremely low resistance values (0.01  to 0.1 )

• All welded construction

• Solid metal nickel-chrome resistive element with low TCR

(< 20 ppm/°C)

• Very low inductance 0.5 neH to 2 nH

• Excellent frequency response to 50 MHz

• Low thermal EMF (< 3 μV/°C)

• AEC-Q200 qualified ⁽¹⁾

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

Note

⁽¹⁾Flame retardance test may not be applicable to some resistor

technologies.
