ESI SR1-10

The SR1-10 Standard Resistor is a laboratory standard of high accuracy and stability. The resistance of 10 ohms is initially adjusted to an accuracy of 20 ppm of nominal, with long term accuracy guaranteed to better than 50 ppm. SR 1-10 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. Goldplated terminals reduce connection errors.
