Winding InstructionUse 3,50 mm margin (item [3]) on the left side. Use 3,50 mm margin (item [3]) on the right side.

Primary Winding (Section 1)Start on pin(s) 4 using item [6] at the start leads and wind 40 turns (x 1 filar) of item [8]. in 2 layer(s) from left to right. Winding direction is clockwise. Add 1 layer of tape, item [5], in between each primary winding layer. At the end of 1stlayer, continue to wind the next layer from right to left. On the final layer, spread the winding evenly across entire bobbin. Finish this winding on pin(s) 3 using item [6] at the finish leads.Add 3 layers of tape, item [4], for insulation.

Secondary WindingStart on pin(s) 6,7 using item [6] at the start leads and wind 4 turns (x 6 filar) of item [9]. Spread the winding evenly across entire bobbin. Winding direction is clockwise. Finish this winding on pin(s) 8,9 using item [6] at the finish leads.Add 1 layer of tape, item [4], for insulation.Start on pin(s) 10 using item [6] at the start leads and wind 8 turns (x 4 filar) of item [10]. Spread the winding evenly across entire bobbin. Winding direction is clockwise. Finish this winding on pin(s) 6 using item [6] at the finish leads.Add 3 layers of tape, item [4], for insulation.

Feedback WindingStart on any (temp) pin on the secondary side and wind 8 turns (x 4 filar) of item [11]. Winding direction is clockwise. Spread the winding evenly across entire bobbin. Finish this winding on pin(s) 1 using item [6] at the finish leads. Moveend of wire from temp pin and terminate it on pin 2.Add 2 layers of tape, item [4], for insulation.

Primary Winding (Section 2)Start on pin(s) 3 using item [6] at the start leads and wind 40 turns (x 1 filar) of item [8]. in 2 layer(s) from left to right. Winding direction is clockwise. Add 1 layer of tape, item [5], in between each primary winding layer. At the end of 1stlayer, continue to wind the next layer from right to left. On the final layer, spread the winding evenly across entire bobbin. Finish this winding on pin(s) 5 using item [6] at the finish leads.Add 3 layers of tape, item [4], for insulation.

Core AssemblyAssemble and secure core halves. Item [1].

VarnishDip varnish uniformly in item [7]. Do not vacuum impregnate.

Comments1. Pins 6 and 7 are electrically shorted to each other on the PCB via a copper trace.

2. Pins 8 and 9 are electrically shorted to each other on the PCB via a copper trace.3. Use of a grounded flux-band around the core may improve the EMI performance.
