Winding Construction:
Winding Constructions Notes:
1. All windings shall be wound in the
2 Layers Tape
same direction.
2. Winding shall be evenly distributed
to minimize buildup.
3. Inter-winding tape shall come in
contact with both flanges around the
entire periphery of the winding.
4. Winding direction produces crossover
(7-9) 2 Turns 3x AWG #24 H
(10-12) 7 Turns 3x AWG #24 H
3 Layers Tape
(6-4) 6 Turns AWG #24 H
to maximize distance from wire to core
(1-3) 32 Turns 0.5mm TEX-E
to comply with safety requirements.
Assembly Instructions:
Assembly Instructions Notes
1. Dip solder terminals.
2. The mating surfaces of the cores shall be
clean and free of debris
3. Cure varnish per supplier datasheet
recommendation.
4. Stamp-print or apply label per mechanical
specification.
5. Dip varnish.
Testing Instructions:
Testing Instructions Note:
1. All tests in electrical specification shall be
performed 100%unless specified in this
section.
