MATERIAL B-16 (Permeabilität 120)
Eine Ringkonfiguration bietet die ultimative Nutzung der Eigenschaften des intrinsischen Ferritmaterials. Ringkerne werden in einer Vielzahl von Anwendungen eingesetzt, z. B. als Eingangsfilter, Fehlerstromschutzschalter, Gleichtaktfilter und in Impuls- und Breitbandtransformatoren.
Ein Nickel-Zink-Material, das mittlere Temperaturstabilität, aber eine hohe Güte bietet (0,2 bis 15 MHz). In erster Linie Ersatz als Ringkern in Spulen hoher Güte. Auch lieferbar in Stabform oder als Breitband-Balunkern.

Features
NiZn ferrite material with a range for inductive applications up to 25 MHz, that can be used for EMI applications to suppress noise frequencies above 200 MHz.
Burnished to break sharp edges, can contain Parylene C coat at smaller diameters from the length of 9.5mm (0.375") or a uniform coating of thermo-set plastic at larger dimensions (if part numbers ends with a C).
Toroide werden auf AL-Werte bei 10 kHz getestet.
A high frequency NiZn ferrite developed for a range of inductive applications up to 25 MHz. This material is also used in EMI applications for suppression of noise frequencies above 200 MHz. EMI suppression beads, beads on leads, SM beads, wound beads, multi-aperture cores, round cable snap-its, rods, antenna/RFID rods, and toroids are all available in 61 material. Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.
