I was involved with high-voltage power supplies in which transformers were wound using 3019-sized ferrite cores. Transformer structures were essentially the following: Figure 1 Pot core based ...

It's always a good thing to eliminate manual winding on a pc board. You can do so with the AVX low-profile E-Core series, which mounts on the board and lets you use board tracks for windings of ...

The well-known problem of defining the minimum inductance value for a target roll-off and dc current is addressed in the frame of a hysteresis model. Mauricio Esguerra, Ferrite Division, EPCOS AG, ...

E-core shapes allow assembly ease. Nienchtze Teng, Magnetics Div. Spang, Butler, Pa. Magnetic cores for power supply inductors require careful selection because of the important role they play. An ...

At present, portable receivers generally use ferrite rod antennas for LF and MF (below 2 MHz), and whip antennas for HF (up to 30 MHz). Each type has proved effective in its particular application.
