Revision: 06-Oct-08

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

Ω to 0.1 Ω)

• All welded construction

• Solid metal Nickel-Chrome resistive element with low TCR

(< 20 ppm/°C)

• Lead (Pb)-free construction is RoHS compliant

• Very low inductance 0.5 nH to 2 nH

• Excellent frequency response to 50 MHz

• Low thermal EMF (< 3 µV/°C)

Note

• Part Marking: Value, RTC/Stability code
