Yesterday I was building an LCR meter which wasn't functioning correctly. After some researh online I found that the self reasonant frequency of inductor has a part to play as well. If I understood the video correctly, the self reasonant frequency is basically the frequency where the inductor stops functioning without being connected to any other components. According to the specs from Farnell, my inductor only has a reasonant frequency of 1K. oops
The problem is I built lady ada's minty boost phone charger with an inductor I don't have the spec for. How do I know the self resonant frequency is correct? I have had stability issues with the circuit before. I suspect the inductor is pants.
