The Model SR1 Standard Resistor is a laboratory standard of high
accuracy and stability. The resistance of most values is initially
adjusted to an accuracy of 20 ppm of nominal, with long term
accuracy guaranteed to better than 50 ppm. Model SR1 has been
constructed to meet today's high standards of performance. The
resistance wire used is a modern alloy having excellent stability,
extremely low temperature coefficient over a wide range of
temperatures, and very low thermal emf to copper. A unifilar winding
on a flat mica card is used to minimize both series inductance and
shunt capacitance. The durable aluminum case provides electrostatic
shielding. Gold-plated terminals reduce connection errors.
