Summary
The low cutoff frequency f
the ferrite material selection. The material with the highest initial
permeability at f
Manganese zinc ferrites, 77 and 78, can be used to a cutoff
frequency f
ferrite, again depending upon the frequency f
material.
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 fre-
quency designs, use nickel zinc ferrite. The toroidal and multi-
aperture cores are the recommended 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 Bead, Balun and Broadband Kit II, part number 0199000011,
contains a variety of components suited for broadband trans-
former design evaluations, see page 92.
