Can someone help me understand the recommended EMC circuit in this datasheet:

https://www.cui.com/product/resource/v78w-500.pdf

Its at the bottom of page 4, I don't recognize the big 'Z' symbol.  Also attached.  Thank you for any help!

That "Z" just indicates that the two inductors share a common core -- otherwise called a "common mode choke".  It's another way of drawing a transformer, when the windings are far apart on the schematic.
We'll search out every place a sick, twisted, solitary misfit might run to! -- I'll start with Radio Shack.
