Create a capacitor from .subckt

QSPICE

Can anyone explain how to create a capacitor from the following, I tried just pasting into QSPICE but it does not create a working capacitor:

I just highlight one of them and pasted it into a schematic. But you can paste all in an select which one you want in the 3rd party import GUI thing.

Anyway, it looks to me like it’s a capacitor from DC to about 10kHz. From 10kHz to 2MHz, it’s a resistor, and thereafter it’s an inductor.

Thanks Mike, yes I can reproduce your simulation now.
