Resistors : ESI SR1-1K

The SR1-1K Standard Resistor is a laboratory standard of high accuracy and stability. The resistance of 1 Kohms is initially adjusted to an accuracy of 20 ppm of nominal, with long term accuracy guaranteed to better than 50 ppm. SR1-1K 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. Resistance: 1 kohm Accuracy (Initial): 20ppm Accuracy (Longterm): 50ppm Accuracy (Calibration): 10ppm Calibration Condition: 23?C, low power, four-terminal measurement Temperature Coefficient: 5ppm/?C Maximum Power: 1000mW Maximum Current: 10mA
