MATERIAL 86 (Permeabilität 20)

Ein Nickel-Zink-Material mit hohem Volumenwiderstand und ausgezeichneter Temperaturstabilität. Hohe Güte zwischen 80 und 180 MHz. Ist für HF-Spulen, Antennen und Breitbandverstärker ebensogut geeignet wie für Linearendstufen. Lieferbar in Ringform.

Unser NiZn-Ferrit mit der höchsten Frequenz ist für Breitbandtransformatoren, Antennen und Hi-Q-Induktivitätsanwendungen bis 150 MHz vorgesehen.

Starke Magnetfelder oder übermäßige mechanische Beanspruchungen können zu irreversiblen Veränderungen der Durchlässigkeit oder der Verluste führen.

Our highest frequency NiZn ferrite intended for broadband transformers, antennas and Hi Q inductor applications up to 150 MHz.

Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability or losses.

Die oben genannten Eigenschaften sind typisch für Amidon MnZn- und NiZn-Ferrite.

The above quoted properties are typical for Amidon MnZn and NiZn ferrites.

This NiZn is our most popular ferrite for suppression of conducted EMI from 20 MHz to 250 MHz. This material is also used for inductive applications such as high frequency common-mode chokes. EMI suppression beads, beads on leads, SM beads, multi-aperture cores, round cable EMI suppression cores, round cable snap-its, flat cable EMI suppression cores, flat cable snap-its, miscellaneous suppression cores, bobbins, and toroids are all available in 43 material..

43 Material is used for EMI/RFI suppression in the 20 MHz to 250 MHz range.

FT50A-61

MATERIAL 61 (Permeabilität 125)

Ein hochfrequenter NiZn-Ferrit, entwickelt für eine Reihe von induktiven Anwendungen bis 25 MHz. Dieses Material wird auch in EMI-Anwendungen zur Unterdrückung von Störfrequenzen über 200 MHz verwendet. EMI-Unterdrückung Perlen, Perlen auf Leitungen, SM-Perlen, Wundperlen, Multi-Apertur-Kerne, Rundkabel snap-its, Stangen, Antenne / RFID-Stäbe und Toroide sind alle in 16 Material erhältlich. Starke Magnetfelder oder übermäßige mechanische Beanspruchungen können zu irreversiblen Veränderungen der Durchlässigkeit und der Verluste führen.

MATERIAL A-43 (Permeabilität 850)

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).

Coating Options:
