- Cut 15 cm (6”) of 0.5 mm enameled wire and wind 8 turns on the black FT37-43 toroidal core. Wind
the wire tightly on the core, avoiding loose turns, and spread the turns evenly around the core. They
should be uniformly spread around the circumference of the toroid. Leave pigtails of about 10-20 mm
(0.70”).
- Now take a resistor leftover of 15 – 20 mm (1/2-3/4 in) to make the 1 turn secondary (remember, one
turn means that the wire goes once through the toroid core). Please try to make a snug fit of this turn to
the core.
- Prior to its soldering, use a cutter, or sandpaper to scrape the enamel from the pigtails of the 8 turn
winding.
IMPORTANT: Wind the T5 transformer exactly as shown in the pictures. You must follow both the
number of turns and the winding direction.
