Hi all,
I received an audio transformer for a project from my prof and went ahead and started to characterize it before using it.
CT-side DC resistance: 46R
Non-CT-side DC resistance: 2R
Voltage gain ratio: 1:13
The part is an audio transformer (1.2K primary, 8R secondary) 60-282-0
While doing LC tank measurements to figure out the inductance, I determined the resonant frequencies with different parallel capacitor values (1nF, 1.5nF, and 10nF) and both the primary and secondary windings had roughly the same inductance 10-12 uH.
Maybe I'm just double-guessing myself but shouldn't the ratio of inductance be roughly the turns ratio and not one?
For each measurement, I left the other winding open and unconnected.
Thank you,
JP
