This project (where I sourced the non-SMD parts myself) required an SMD 7.5 uH common mode choke. I didn't have any, so I made my own substitute!

It turned out to be 62 uH, so I overshot the inductance a little... 😁

Bending the ends around the bottom to match the PCB footprint worked surprisingly well!

I bought the PCB here: https://www.tindie.com/products/mustoradio/ham-radio-antenna-switch/

@raek My modular tuner project has a bunch of stuff like that which interoperates

I handled the isolation using small 100uH axial inductors and 100 nF ceramic capacitors
