ELESA rectangular amorphous magnetic cores are manufactured from iron-based metallic alloys with a disordered, non-crystalline atomic structure.
Their approximate composition is 85–95% iron (Fe), 1–5% boron (B) and 5–10% silicon (Si), with a magnetic saturation of 1.50 T and strip thicknesses of just a few tens of micrometres.
Lower eddy-current losses, particularly beneficial when operating at higher frequencies.
Enables efficient magnetic flux conduction.
Maintains magnetic properties over a wide temperature range.
Improved acoustic performance at frequencies up to 3–4 kHz.
The cores can be supplied with an anti-corrosion paint finish which, in addition to improving their appearance, makes them easier to handle.
