With an overall height of only 0.350", these variable inductors are ideal for applications where low-profile circuit boards & high Q values are essential. The coils ...

[Scott Harden] has been working through a design for a variable inductor to use as a PTO, or permeability tuned oscillator. What you see above is the most recent fruit of these efforts. The ...
