Balun Ferrite Transformer

These cores are accordingly coiled and applied as “Balun” transformer in the input circuits of television sets. The essence of their operation is that they adapt the symmetrical dipole antenna to the asymmetrical input of the set. The symmetrizing transformer cores are made in 4 different sizes. In STN normal and STM miniature finish.
