I am building a FM transmitter (Max2606 FM Transmitter Project). There is an inductor that is 380nH that must be installed. I checked all the pieces that came with the project and the only thing that could be the inductor is this little package with a transparent film over it which looks like it has a square piece of ferrite inside. There are 2 holes at one end of the package. There are no markings of any kind on this package. Is this the inductor? Is there an inductor inside? Help lol
