Well, you did get it right on your posts heading, excepting, that the unit is composed as one word. Ferroxcube, a long time and prime manufacturer of ferrite/powdered iron/ceramic products.
RFI beads and cores, ferrite power transformers cores, flyback cores, pot cores.
However, in equipment that I see nowadays, I am equally more apt to see TDK, Siemens, or Arnold as the manufacturer, as well as the Oriental sources.<p>You will find a wealth of tech specs and app notes at their website:
(Most of USA referral is to the El Paso, Tx site) <p>Also there is more info on ferrite products at:
<p>This site gives some cross referencing of core material between different manufacturers:
<p>As well as encompassing the TDK line in:
<p>Also,right next door to you, since the ‘80’s in Garland. with their Ferrite product line is:
<p>With your adjunct reference to bobbins, that would lean towards your interest in pot cores or D cores, possibly for power transformer utilization. If such is the case, have you considered the salvaging of a core unit from a defunct/discarded computer SwMode power supply. Their cores would be designed for the 200-300 watt power levels. I have used many of those units by just filing or Dremel tooling away the cores peripheral captive epoxy bead to get apart and access to the bobbin, and most then unwind successfully for rewind and reuse. (Excepting a select few clear epoxy encapsulated windings/units.) <p>73's de Edd
