I watched the video and read the postings. This was a great presentation for help understanding why a choke would be needed.
I still have a question, are there different choke specs that are needed for each type of application, Non MTH engine, Passenger car lighting and Transformer, or is it a case of one choke spec (22uH) will fit all these types of applications.

You’re just looking for an inductance >10uH so the impedance is high enough, and that that works up to maybe 10MHz. The top frequency of an inductor or choke is specified as self-resonant frequency or (SRF).
