Ribbon Microphone Transformer
LL2913
LL2913 is identical to our ribbon microphone transformer LL2911, but (for manufacturing reasons) with
a different pinout / winding phase.
Turns ratio:                                                    1 + 1 + 1 + 1 : 37
Dims: (Length x Width x Height above PCB (mm))                  30 x 22.5 x 14.5
