Hi,

I found this transformer inside an EL inverter(110V/ 900 HZ output). Does anyone knows the pinout or how to wire it.
 

That kind of transformer is custom made for the TV/monitor so you will not find a data sheet or information about it. You can do a resistance check to find the ends of the windings and make a guess that the pins with more than one wire are the primary side but that's about all. If you know the model of TV/monitor it came from you might be able to findout from it's service manual.

Expect it to use somewhere around 25 -30V at the primary and step it up to around 200V at the secondary and operate at a frequency around 20KHz. The power rating will be low, probably 5W or less.

you can measure inductance of each coil....beware of some are connected with more than two terminals........then you find how they are polaised.....give one end a "dot".....to say its positive polarity say...then go from there.......if you measure two separate coils and get say 1mH EACH ...then you put them in series and measure the total and its less than 1mH, then you know that they are opposite polarity connected in your measurement....so you can get all the dot notation for the trafo like that.

Remember its N1/N2 = ROOT(L1/L2)
