into design
• Ideal for all types of current sensing, voltage
division and pulse applications including
switching and linear power supplies,
instrumentation, power amplifiers
• Proprietary processing technique produces
extremely low resistance values (down to
0.001 )
• 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)
• Integral heat sink not utilized for resistance values less
than 0.0075 
• AEC-Q200 qualified ⁽¹⁾
• Material categorization: For definitions of compliance
please see www.vishay.com/doc?99912
