CAPACITOR parameters - pspice

CAPACITOR

The symbol for a capacitor is C .The name of a capacitor must start with C, and it takes the following general form
C(name)N+ N- CNAME CVALUE IC=Vo
N+ is the positive node and N- is the negative node. The voltage of node N+ is assumed positive with respect to node N-, and the current flows from node N+ through the capacitor to node N-. CNAME is the model name, and CVALUE is the nominal value of the capacitor, IC defines the initial (time zero) voltage of the capacitor, Vo.
If CNAME is omitted ,CVALUE is the capacitance in farads ,and the CVALUE can be positive or negative but must not be zero .

MODEL PARAMETERS FOR CAPACITORS
Name Meaning Units Default
C Capacitance multiplier 1
VC1 Linear Voltage Co efficient Volt -1 0
VC2 Quadratic Voltage Co efficient Volt -2 0
TC1 Linear Temperature Co efficient °C -1 0
TC2 Quadratic Temperature Co efficient °C -2 0


C is a capacitance multiplier, rather than the value of the capacitance .It scales the actual capacitance value .CVALUE ,thus ,C=1.1 means that CVALUE is multiplied by 1.1,not that CVALUE is 1.1F
