The R_Card record holds the technology parameters for a semiconductor resistor, R_Resistor.

$R_{\mathrm{int}}\=\{\begin{array}{cc}R& R\>{\mathrm{-10}}^{40}\\ \mathrm{\rho }\frac{\mathrm{length}-\mathrm{narrow}}{\mathrm{width}-\mathrm{narrow}}& \mathrm{otherwise}\end{array}$

$\mathrm{\rho }\=R_{{\mathrm{SH}}_{\mathrm{int}}}\left(1\+{\mathrm{TC}}_1\mathrm{\ΔT}\+{\mathrm{TC}}_2{\mathrm{\ΔT}}^2\right)$

$R_{{\mathrm{SH}}_{\mathrm{int}}}\=\{\begin{array}{cc}{R}_{\mathrm{SH}}& R_{\mathrm{SH}}\>{\mathrm{-10}}^{40}\\ 1000& \mathrm{otherwise}\end{array}$

$\mathrm{\ΔT}\=T_R-T_{\mathrm{NOM}}$

$T_R\=273.15\+\{\begin{array}{cc}T& T\>{\mathrm{-10}}^{40}\\ T_{\mathrm{NOM}}& T_{\mathrm{NOM}}\>{\mathrm{-10}}^{40}\\ 27& \mathrm{otherwise}\end{array}$
