24x12x6mm "E". Ferrite cores
Ferrite cores used for traditional analog communication and modern digital communication: power transformers, current transducers, instrument transformers, inductors, chokes, ballasts, voltage stabilizers and regulators, welding transformers, broad band transformers, filters, old PC as ferrite memory, etc.. Good for any high-end audio, video, Microphones, band instrument or computer system.
Ferrite core is generally stored near signals of place. With high-temp resistant and corrosion resistant.
It has isolation eddy current, low permeability and constant magnetic characteristics.
