Wire-wound resistor RS3 series

high-currentreference

4 terminal construction, high stability resistance standard - Wide range 0.0001 ohm to 1 Mega ohm - Excellent load coefficient The RS3 range of resistance standards are constructed using carefully selected low temperature coefficient Manganin or Zeranin wire, depending on the value, mounted on formers which have a high mechanical stability. The wires are wound in a strain free manner and heat treated to remove any stresses. They are also artificially aged under the strictest control. The result is a standard of high quality with long term stability and permanence of calibration combined with a low temperature coefficient. The RS3 range also offers a high current carrying capability which makes them ideal for applications where precise current needs to be measured. The resistance standards type RS3 were primarily designed as DC standards, however values above 0.1 ohm are non inductively wound and the adjacent AC characteristics are typical
