FT82-61

Material 61 Permeabilität 125

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.

Für 160 m bis 10m bestens geeignet, da sehr geringe Permeabilität und sehr Breitbandiges - Material. Bei diesem Ringkern handelt es sich um einen Nickel-Zink Ferrit für Leistungsbalune bis ca. 50 Watt. Wir empfehlen etwa 10 Windungen im KW-Bereich. Im Bereich von 14-28 MHz genügen auch 5-8 Windungen, während auf 160m ein paar Windungen mehr nötig sind ca. 13-16. Bei höheren Sendeleistungen können zwei oder drei Kerne "gestapelt" werden. Nickel-Zink Ferrite mit einer Permeabilität von 125 werden insbesondere für die niedrigen Bänder 160 - 80 - 40m empfohlen, da mit Eisenpulverkernen - rot, -2 Mischung, Permeabilität 10 - dort keine ausreichend hohen Induktivitäten aufgebaut werden können. Bänder - 160 - 80 - 40m -20m-10m.

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 61 Material erhältlich. Starke Magnetfelder oder übermäßige mechanische Beanspruchungen können zu irreversiblen Veränderungen der Durchlässigkeit und der Verluste führen.

61 Material Ferrit ToroidsFerrite Toroids 61 Material und ist für induktive Anwendungen bis 25 MHz ausgelegt und unterdrückt darüber hinaus Rauschfrequenzen von 200 MHz bis 1000 MHz

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.

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.

61 Material Ferrite ToroidsFerrite Toroids 61 Material and is designed for inductive applications up to 25 MHz and also suppresses noise frequencies from 200 MHz to 1000 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).

Beschichtungsoptionen:

- Toroide mit einem Außendurchmesser von 9,5 mm (0,375 ") oder kleiner können mit Parylen C beschichtet werden. Die Parylene-Beschichtung erhöht die Abmessungen "A" und "C" und verringert die Abmessung "B" um maximal 0,038 mm (0,0015 "). Die neunte Ziffer einer Parylene-beschichteten Toroid-Teilenummer ist eine "1". Siehe Referenztabellen für die Materialeigenschaften von Parylene C. Parylene C-Beschichtung sind RoHS-konform.
- Thermoplastisch beschichtete, kunststoffbeschichtete Teile können einer Mindestdurchschlagsspannung von 1000 Vrms widerstehen, die gleichmäßig über die "C" -Abmessung des Toroids angelegt wird.

Coating Options:

– Toroids with an outside diameter of 9.5 mm (0.375″) or smaller can be supplied Parylene C coated. The Parylene coating will increase the “A” and “C” dimensions and decrease the “B” dimension a maximum of 0.038 mm (0.0015″). The ninth digit of a Parylene coated toroid part number is a “1”. See reference tables for the material characteristics of Parylene C. Parylene C coating is RoHS compliant.

FT82-67

MATERIAL 67 (Permeabilität 40)

Ein Nickel-Zink-Material mit großer Ähnlichkeit zu Material 63. Hat ausgezeichnete Stabilität und einen erweiterten Frequenzbereich von 10 bis 80 MHz sowie eine höhere Flußdichte gegenüber Material 63, dagegen einen etwas niedrigeren Volumenwiderstand. Sehr gut geeignet für HF-Anwendungen hoher Güte. Wird verbreitet für Breitbandverstärker und Linearendstufen eingesetzt.

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.

Toroide werden auf AL-Werte bei 10 kHz getestet.
