Dear amirul
There are two questions，please try to do your best to give us feedback. this is very important for EE19 transformer.
1.From your transformer pin layout, you show A,B,C,E,D
2.But from our bobbin pin circuit, we remark 1,2,3,4,5,6 on bobbin drawing.
So we can see A=3, B=2, C=1,D=4,E=6 ,is it right?
3.Just now we have calculated secondary inductance=42mH,primary inductance=0.412mH.EE19 PC40 core can not match this inductance.
We will have two solution.please help to confirm to us.
PlanA: you have original samples in your hand, can you use LCR tester to check the secondary inductance and primary inductance for us?
PlanB:we think the primary inductance 0.412mH is basing on 183Ts.
And we can make gap for you if 183Ts to reach 0.412mH,so
D from E is primary winding,not secondary winding.could you help to double check.sorry of our carefully,because we must make everything clearly.
