As I have said before, there is no such thing as too many reactance charts. This one appeared in a 1952 issue of Radio & Television News. If you do a lot of experimenting with circuit design, then having a chart like this one handy can save a lot of time compared to punching numbers into a calculator. A quick scan of the chart give you a useful overview of where your component value lies within the realm of operating frequency. Smartphone apps and computer programs are nice for calculating exact values, but when you're futzing around with optimizing a filter, impedance matching, or interstage signal coupling, the visual aide of a chart can be a great advantage.
