Just leave the middle wire open.
AFAIK, the VTL5C3/2 is just a center tapped VTL5C3.
You can also just use one half of the cell (leave
one of the outer wires open) and get 1/2 the resistance,
or even connect the two halves in parallel (short the
two outer wires together) and get 1/4 the resistance.
As these devices have rather high tolerance, you might
try the different options and see what fits best into your
application.
