ZERO OHM COIL

ZERO OHM COIL
The zero ohm coil (ZOC) is a special form of transformer core coil. This is also made of
the top quality material FERON described in the chapter "Transformer Core Coils". In
the ZOC, an air gap is calibrated and adjusted by hand between the two laminated
cores (one I-shaped and one E-shaped). The air gap determines the inductivity of the
coil and demands great care in the manufacturing process. It must not be too small, as
saturation effects would otherwise occur at high loadings. The high production costs of
the ZOC, and thus its higher price, are always justified when maximum faithfulness in
pulse reproduction is required.
