Electronic – How to specify polarization voltage in polarized capacitors in Orcad Capture
orcad
I have a polarized capacitor like below. it's 1uF and 16V.
the schematic in Orcad is like this:
How can I specify that 16V voltage?

How can I specify that 16V voltage?
You do this: -
1uF 16V
You can even do this: -
1uF 16V 10%
or
1uF 16V 10% TANT
or
1uF 16V 10% ELECT
The value attribute can be however you want it to be.
You can even create new attributes (user defined attributes) than can optionally: -
Be invisible in your schematic
Be seen in your BoM.
On a slightly different note, I would change your symbol to more adequately represent the fact that is for a polarized capacitor. I would also make it less wide so that if you needed to show several parallel capacitors on grid, they don't clash or overlap: -
The answer below is how to properly import a PSpice model (usually generated in a third-party software) into Orcad Capture and PSpice so that both the schematic editor and the simulator work without errors.
Summary
Firstly, the model must be imported into Orcad Capture (so that a new component and a new library .olb is created. Secondly, the model must be properly "fed" to PSpice.
Step 1. Creation of Orcad's component library (.olb file)
Open Orcad Capture -> File -> Import -> PSpice -> OK
Notes:
a) Field Open: path to the PSpice model
b) Field Save as: path to an Orcad library to be created with a new component. Extension must be .opj
c) Field Schematic Configuration File: leave it as suggested
Step 2. Setting up PSpice simulator
Copy and paste your model file (e.g. Model.mod).
Rename the file from Model.mod to Model.lib. This is done, because PSpice works only with .lib extension.
Open Orcad Capture, PSpice -> New Simulation Profile -> Enter any name for the profile (e.g. tran1) -> In an opened window go to "Configuration files" tab -> Library category
Enter the path to Model.lib in the Filename field -> Press Add to Design button
Make sure that the file {Orcad installation directory}\tools\pspice\library\nom.lib is also added to the Configured Files as a Global
Make sure that in the Library Path there is a correct path to the PSpice main library (see the picture above as an example of a proper path).
Final comments
a) Wrt the error you mentioned "ERROR(ORPSIM-15108): Subcircuit LM741/NS used by X_U5 is undefined", this is caused by improper setting of PSpice simulation profile (either improper path to the Model.lib or main Library Path).
b) Overall, the trick is that import of a PSpice model is done twice: once in Orcad Capture and once in PSpice (would have been better if done automatically by the program).
c) Of course, to add the component in Capture, one needs to add the library (Model.olb) in a Place Part subwindow.
d) Not sure, but likely names of the files Model.lib and Model.olb must be the same, so that PSpice knows what Spice model to use.
