4 conductor Tape
1/2″ (12.7 mm) wide; has the highest watt density and the most variety of resistances.
It can have leads at one end in the case of a series connection or a series/parallel connection, or leads at either end in a parallel connection.
The tightest wrap this tape can achieve is on a 1/4″ (6.3 mm) O.D. surface.
A smaller tube should be wrapped with 1/4″ (6.3 mm) or 1/6″ (4.2 mm) tape.
2 conductor Tape
1/4″ (6.3 mm) wide; has leads on one end in the series connection, and leads at both ends for parallel connections.
This tape will wrap down to 1/8″ (3.17 mm) O.D.
1 conductor Tape
1/6″ (4.2 mm) wide; can wrap down to .060″ (1.52 mm) O.D.
A lead will be present at both ends.
