division and pulse applications including

switching and linear power supplies,

instruments, 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)

• AEC-Q200 qualified ⁽¹⁾

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

Notes

* Lead (Pb)-containing terminations are not RoHS-compliant.

Exemptions may apply.

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

technologies.
