MATERIAL A-98 (Permeabilität 10.000)
-98 Material ist ein Material mit hoher Permeabilität, das für EMI / RMI-Unterdrückung, Gleichtaktdrosseln, Impuls- und Breitbandtransformatoren verwendet wird.
-98- material is a high permeability material used for EMI/RMI suppression, common mode chokes, pulse and broadband transformers. Available in shapes and toroids.
Das -98 Material hat Industriestandard für Materialien mit hoher Permeabilität gesetzt.
In Filteranwendungen hat das Material 98 zu 20% - 50 % mehr Impedanz unter 1 MHz als J perm.
