2.8.5 Changing a Placed Inductor’s Value
 To change the value, and other parameters of a placed inductor:
1. Double-click on the inductor and select the Va lu e tab.
2. Select the desired inductance from the Inductance(L) list. If it is not there, type the value
you want.
3. Select the desired tolerance from the To l er ance list, or type in a value.
4. Optionally, enter information in the Component Type (for example, coil) and Hyperlink
fields.
5. Optionally, enable the Additional SPICE Simulation Parameters field described below:
•
Initial Conditions checkbox — enable and then enter an initial current for the inductor.
6. Optionally, change the Layout Settings as described below:
•
Edit Footprint button — click to display the Edit Footprint dialog box where you can
select a new
Footprint and Manufacturer.
Note For information on placing inductors, and information on how to edit footprints, refer
to the
Multisim User Guide or the Multisim helpfile.
2.9 Advanced Inductor
 To change the parameters of an advanced inductor:
1. Double-click on the placed inductor and select the Value tab.
2. Change the parameters listed below as desired:
•
Nominal Inductance (Lo) — inductance at low frequency/current.
•
Inductor Self Resonant Frequency (fo) — frequency at which the impedance.
magnitudes of the nominal inductor and the parasitic capacitor are equal.
•
Inductor Series Resistance (Rdc) — resistance of the inductor winding.
•
Inductor Quality Factor (Q) — quality factor of the parallel RLC combination.
•
Inductor Rated Current(Idc) — current at which the nominal inductance reduces to
90%.
3. Click OK.
