Application

RWE precision resistors are designed for use in professional electronic devices, control and measurement equipment and control systems. They are particularly recommended for systems requiring high accuracy, high stability and low sensitivity to temperature changes.

Operation characteristics

  • RWE type resistors meet the requirements for the highest stability class according to PN-86/T-80051.
  • Climatic category: 55 / 125 / 56
  • Resistance change during storage: below 0.02% / year
  • We manufacture resistors in two types: RWE0207 and RWE0414, differing in size and rated power.

over 1 M2max. 1.0

Additional information

  • We make resistors with any resistance value from the given range,
  • We make resistors with parameters individually agreed with the recipient,
  • For resistors with a tolerance of 0.01 to 0.05%, we recommend using a load of up to 50% of the rated power.

Packing

Resistors are packed in bags foil. Each bag is provided with a label with the following information:

manufacturer – resistance – tolerance – TWR – number of pieces

Depending on the temperature coefficient of resistance (TWR), different label colors are used:

3 x 10-6 / K – 3 ppm
gray
5 x 10-6 / K – 5 ppm
purple
10 x 10-6 / K – 10 ppm
blue
15 x 10-6 / K – 15 ppm
orange
25 x 10-6 / K – 25 ppm
yellow
50 x 10-6 / K – 50 ppm
red
