Hi Roman, It is out of a dog collar. Basically takes 7 volts stored in a 470uf cap and converts it to 300 volts on the forward pulse for 250us (10K load) and can create 12Kv for 20uS on the flyback into 10meg shunted by 2pf. I am guessing it is probably around 100:1 on the turns ratio (the forward pulse losses look about right), but wanted to find out the primary and secondary inductances and I DON'T HAVE AN IMPEDANCE BRIDGE!!!! (a little frustration) I guess I'll just have to charactize it the old fashion way... spectrum analyzer and tracking generator. Should get me close. But I would love just to call the company, get the parameters and ask them to wind them for me (or buy the same transformer for my application... a better dog collar!)

It has a part number IPL-1032-22. Does anyone recognize this part number? I was hoping to locate the manufacturer. > > > What is it from?
