You misunderstood my post, I was merely showing that the inductance and the resistance are equal for the two halves of the KNF winding.

No, nothing is missing, you can use it as is.

Since there is no symbol of Quad II OPT in Auymi's web. In order to use his SPICE Model I have made a symbol myself.
14.JPG

and I tried to map the pins of Symbol with SPICE Model
18.JPG
but there is some pins that I can not find in SPICE code, like Pin8 to Pin13

further more there are some numbers(Marked in red) in SPICE code that I have no ideal what are they meaning for?
19.jpg

for example, in the following code
* Primary inductance (p-p 3000ohm 11H)
L11 P1 11 2.75H
L12 12 P2 2.75H


It seems that the number 11 refers to B1 and number 12 refers to B2

but in the next following code
*Primary DC resistance
R11 11 B1 100
R12 B2 12 100

It seems that 11 refers to P1 and 12 refers to P2

It is conflicting with each other

You do not need to have pins for the internal connections, such as 31, 21, etc. The symbol’s pin names should correspond to the names used in the model (that’s the easiest way).

Could you give more detail for how to use this in ltspice? I tried this model with my symbol in ltspice, but can not solve the error.

Rename the attached file to "OPT_PP_KNF.asy" and put it in the sym directory.
