WebMar 14, 2014 · A 1% resistor typically has a TC around +/-100ppm/°C, while precision metal foil resistors offer TCs less than 0. 1ppm/°C. Equations 1 and 2 show an example of how you can use a resistor’s TC specification to calculate the change in resistance, ΔR TC of a 1kΩ, ±100ppm/°C resistor when the temperature changes from 25°C to 125°C. WebPower Rating of a Resistor. The power rating of a resistor is the maximum power the resistor can safely dissipate without too great a rise in temperature and hence damage to the resistor. (b) A 9.0-kΩ resistor is to be connected across a 120-V potential difference.
WebNov 17, 2012 · Hello, There is no tolerance option in our rated resistor. The tolerance value of a resistor is simply the deviation on actual resistance. If this was really neccesary for your tests then you would do a maximum/minimum case test anyways (So if you have a 50ohm with 5% tolerance resistor then have two circuits where in the first circuit your resistor will … Web4.
