Place the bobbin item [2] on the mandrel such that pin side on the left side. Winding
direction is the clockwise direction.
Starting at pin 1, wind 60 turns of wire item [4] in two layers. Finish at pin 11.
Apply one layer of tape item [3].
Leave about 1” of wire item [6], use small tape to mark as FL1, enter into slot of
secondary side of bobbin, wind 20 turns in two layers. At the last turn exit the same
slot, leave about 1”, and mark as FL2.
Apply one layer of tape item [3].
Starting at pin 3, wind 20 turns of wire item [5], spreading the wire, finish at pin 2.
Apply three layers of tape item [3] for finish wrap.
Cut FL1 and FL2 to 0.75”.Grind core to get 1.15 mH inductance value. Assemble
and secure core halves. Dip impregnate using varnish item [7].
