Technical Information
f
depending upon the frequency f
For low and medium frequency transformers the optimum core shape
should provide the lowest DC resistance per unit of inductance. If
there is a superimposed dc present the use of gapped cores and
Hanna curves is suggested. For high frequency designs, use nickel
zinc ferrite. The toroidal and multi-aperture cores are the recom-
mended core configurations.
The number of turns should be kept to a minimum to reduce leakage
inductance and self-capacitance of the windings.Wind primary and
secondary windings tightly coupled or as bifilar windings to lower
leakage inductance.
The "Multi-Aperature Core Kit", (part number 0199000036), contains
a variety of components suited for broadband transformer design
evaluations, see page 68.

Manganese zinc ferrites, 77 and 78, can be used to a cutoff frequency
