Termination: Vishay Angstrohm GSR resistors use gold-

plated nickel leads, which are both solderable and weldable

(hot solder dip is available as an option).

FEATURES

• Hermetic glass enclosure is impervious to harmful

environments

• Inert gas filled

• Low noise (- 40 dB)

• Low TCR (down to 15 ppm/°C)

Note
