  • Wirewound VS. Film Resistors
    , they are stable (15-50ppm/yr) maintaining their precision over time because they are made with stable materials. Their TCR (Temperature Coefficient of Resistance) is low (<10ppm/°C) and can be controlled by selecting special wire alloys. (Usually, you need the lowest TCR, but a higher TCR has special interest
  • Understanding Temperature
    A resistor's Temperature Coefficient of Resistance (TCR) tells how much its value changes as its temperature changes. It is usually expressed in ppm/°C (parts per million per degree Centigrade) units. What does that really mean?. Let's use an example: Riedon's 50 ohm 100 Series precision resistor

  • Advanced Medical Applications, Treatment Solutions, and Biotechnology (.pdf)
    that no other technology can match. These include the industry's lowest temperature coefficient of resistance (TCR), and power coefficient (PCR).
  • Power Solution for High-voltage Static VAR Generator (SVG)
    Compared with traditional SVC such as modulator, capacitor reactor and thyristor controlled reactor (TCR), SVG is the best solution in the reactive power control field at present and has unparalleled advantages. In other words, SVG is currently the most advanced dynamic reactive power compensation
  • Why Choose Riedon (a Resistor Company) For Your Special RTD Requirements
    is its temperature coefficient (TC) or temperature coefficient of resistance (TCR). TC or TCR is usually stated as a constant; parts per million per degree per Centigrade (ppm/ C). This property is the basis for designing RTDs. A Resistance Temperature Detector (RTD) is a resistor designed to measure
  • The `Good Old` Power Days (.pdf)
    technology resistors still fall short of wire-wounds. Look at the chart: athough metal foil technology is a close second to wirewounds, other technologies are generally unable to measure up in power rating, tolerance and TCR.
