Resistance-Temperature Characteristics

Resistance-Temperature Characteristics depict resistance value at zero-power versus temperature. This relationship is expressed mathematically as:

R₁ = R₂ *e [β(1/T₁-1/T₂] (eq. 1)
Where:
T₁ = absolute temperature (K) at any point
T₂ = absolute temperature (K) different from T₁
R₁ = resistance (Ω) with zero power at T₁
R₂ = resistance (Ω) with zero power at T₂
β = constant [K]

Equation (1) depicts linearity as a logarithm of Zero-Power Resistance versus the reciprocal of temperature. Some examples of Resistance-Temperature Characteristics are shown in the R-T Characteristic Examples (Figure 1).
