FT114A-16

MATERIAL 16 (Permeabilität 120)

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.

Nickel-Zink Ferrite mit einer Permebilität von 120 werden insbesondere für die niedrigen Bänder 160 - 80 - 40m empfohlen, da mit Eisenpulverkernen - rot, -2 Mischung, Permeabiltät 10 - dort keine ausreichend hohen Induktivitäten aufgebaut werden können.

Bei diesem Ringkern handelt es sich um einen Nickel-Zink Ferrit für Leistungsbaluns bis ca. 100 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.

 Ferrit-Ring für Breitbandtransformatoren, Frequenz hohe Güte bis 200 MHz

Werte geprüft bei 10 kHz und <10 Gauß

A nickel-zinc material that offers medium temperature stability but high quality (0.2 to 15 MHz). First and foremost replacement as ring core in coils of high quality. Also available in rod form or as a broadband balun.
Nickel-zinc ferrites with a permeability of 120 are recommended especially for the low bands 160 - 80 - 40m, because with iron powder cores - red, -2 mixture, permeability 10 - there can not be built up sufficiently high inductivities.
This ring core is a nickel-zinc ferrite for Leistungsbaluns up to about 100 watts. We recommend about 10 windings in the KW range. In the range of 14-28 MHz also 5-8 turns are sufficient, while at 160m a few turns more are needed ca.13-16. At higher transmit power, two or three cores can be "stacked".
Ferrite ring for broadband transformers, frequency high quality up to 200 MHz

16  Material Ferrite ToroidsFerrite Toroids 16 Material and is designed for inductive applications up to 25 MHz and also suppresses noise frequencies from 200 MHz to 1000 MHz

Suitable for 160 m to 10 m, as very low permeability and very broadband material !!

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.

Nickel-Zink Ferrite mit einer Permebilität von 120 werden insbesondere für die niedrigen Bänder 160 - 80 - 40m empfohlen, da mit Eisenpulverkernen - rot, -2 Mischung, Permeabiltät 10 - dort keine ausreichend hohen Induktivitäten aufgebaut werden können.

Bei diesem Ringkern handelt es sich um einen Nickel-Zink Ferrit für Leistungsbaluns bis ca. 100 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.

 Ferrit-Ring für Breitbandtransformatoren, Frequenz hohe Güte bis 200 MHz

Werte geprüft bei 10 kHz und <10 Gauß

A nickel-zinc material that offers medium temperature stability but high quality (0.2 to 15 MHz). First and foremost replacement as ring core in coils of high quality. Also available in rod form or as a broadband balun.
Nickel-zinc ferrites with a permeability of 120 are recommended especially for the low bands 160 - 80 - 40m, because with iron powder cores - red, -2 mixture, permeability 10 - there can not be built up sufficiently high inductivities.
This ring core is a nickel-zinc ferrite for Leistungsbaluns up to about 100 watts. We recommend about 10 windings in the KW range. In the range of 14-28 MHz also 5-8 turns are sufficient, while at 160m a few turns more are needed ca.13-16. At higher transmit power, two or three cores can be "stacked".
Ferrite ring for broadband transformers, frequency high quality up to 200 MHz

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

Suitable for 160 m to 10 m, as very low permeability and very broadband material !!

A nickel-zinc material that offers medium temperature stability but high quality (0.2 to 15 MHz). First and foremost replacement as ring core in coils of high quality. Also available in rod form or as a broadband balun.

MATERIAL 16 (Permeabilität 120)

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.

Nickel-Zink Ferrite mit einer Permebilität von 120 werden insbesondere für die niedrigen Bänder 160 - 80 - 40m empfohlen, da mit Eisenpulverkernen - rot, -2 Mischung, Permeabiltät 10 - dort keine ausreichend hohen Induktivitäten aufgebaut werden können.

Bei diesem Ringkern handelt es sich um einen Nickel-Zink Ferrit für Leistungsbaluns bis ca. 100 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.

A nickel-zinc material that offers medium temperature stability but high quality (0.2 to 15 MHz). First and foremost replacement as ring core in coils of high quality. Also available in rod form or as a broadband balun.
Nickel-zinc ferrites with a permeability of 120 are recommended especially for the low bands 160 - 80 - 40m, because with iron powder cores - red, -2 mixture, permeability 10 - there can not be built up sufficiently high inductivities.
This ring core is a nickel-zinc ferrite for Leistungsbaluns up to about 100 watts. We recommend about 10 windings in the KW range. In the range of 14-28 MHz also 5-8 turns are sufficient, while at 160m a few turns more are needed ca.13-16. At higher transmit power, two or three cores can be "stacked".

FT140-61

MATERIAL 16 (Permeabilität 120)

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.

Nickel-Zink Ferrite mit einer Permebilität von 120 werden insbesondere für die niedrigen Bänder 160 - 80 - 40m empfohlen, da mit Eisenpulverkernen - rot, -2 Mischung, Permeabiltät 10 - dort keine ausreichend hohen Induktivitäten aufgebaut werden können.

Bei diesem Ringkern handelt es sich um einen Nickel-Zink Ferrit für Leistungsbaluns bis ca. 100 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.

 Ferrit-Ring für Breitbandtransformatoren, Frequenz hohe Güte bis 200 MHz

Werte geprüft bei 10 kHz und <10 Gauß

A nickel-zinc material that offers medium temperature stability but high quality (0.2 to 15 MHz). First and foremost replacement as ring core in coils of high quality. Also available in rod form or as a broadband balun.
Nickel-zinc ferrites with a permeability of 120 are recommended especially for the low bands 160 - 80 - 40m, because with iron powder cores - red, -2 mixture, permeability 10 - there can not be built up sufficiently high inductivities.
This ring core is a nickel-zinc ferrite for Leistungsbaluns up to about 100 watts. We recommend about 10 windings in the KW range. In the range of 14-28 MHz also 5-8 turns are sufficient, while at 160m a few turns more are needed ca.13-16. At higher transmit power, two or three cores can be "stacked".
Ferrite ring for broadband transformers, frequency high quality up to 200 MHz

16 Material Ferrite ToroidsFerrite Toroids 16 Material and is designed for inductive applications up to 25 MHz and also suppresses noise frequencies from 200 MHz to 1000 MHz

Suitable for 160 m to 10 m, as very low permeability and very broadband material !!

A nickel-zinc material that offers medium temperature stability but high quality (0.2 to 15 MHz). First and foremost replacement as ring core in coils of high quality. Also available in rod form or as a broadband balun.
Values tested at 10 kHz and <10 Gauss

Bis max. 150 Watt von 160m-10m

Up to max. 150 watts from 160m-10m

Features

NiZn ferrite with a range of 20 to 250 MHz for suppression of conducted EMI, that is used for inductive applications (ex: high frequency common-mode chokes)
