Resistor temperature coefficient setting

[kimi_]

If I have a Resistor for 100Ω 1% ± 20ppm,and need to simulate. How to set the parameters of the Resistor?

Hello,

Double-click the resistor to open its properties, select the Value tab. Here you can configure tolerance, temperature coefficient, etc.

Hi, thank you for reply.

the normal resistor temperature coefficient is like 20ppm. How to select the value, just select TC2 and type number 20 into TC2?

Hello,

TC1 = (Coefficient) (ppm/°C)

Since ppm means parts per million, then we have the following equation:

TC1 = (Coefficient) (10^-6/°C)

For a temperature coefficient of 20 ppm, TC1 = 0.00002.
