The model of the Inductors is identified by the type specifier IND.

.MODEL <model name> IND [model parameters]

Parameters

Parameter Description Default Units
L Inductance multiplier. 1.0  
TC1 Is the linear temperature coefficient and is sometimes given in data sheets as parts per million per °C. To convert ppm specs to TC1 divide by 1E6. 0.0 Ω/°C
TC2 Quadratic temperature coefficient. 0.0 Ω/°C²
TNOM Temperature at which the model parameters were measured. If this value is specified overrides the nominal TNOM value which is set in the options.    °C
TABS Specifies the temperature at which the component operates. This value, if specified, takes precedence over the analysis temperature.    °C
TREL Device temperature relative to current temperature. If this parameter is specified but not the parameter TABS then the current temperature of the component is equal to the current temperature plus TREL.    °C

Temperature effects

After the nominal inductance is calculated, it is adjusted for temperature:

LTEMP = LTNOM · L · (1+TC1(TEMP-TNOM)+TC2(TEMP-TNOM)2)
