  • Beschreibung

Material 72 (Permeabilität 2000)
Ein Mangan-Zink-Material mit großer Sättigungsflußdichte bei hohen Temperaturen. Niedrige Kernverluste im Bereich von 1 kHz bis 1 MHz. Ideal für Transformatoren und Breitbandübertrager bis 30 MHz sowie zur Nebenwellendämpfung zwischen 2 und 40 MHz. Lieferbar in Ring- oder Perlenform sowie als Topf- oder 'E'-Kerne.

Für Breitbandtransformatoren hohe Güte
Frequenz 0,5MHz bis 50MHz

Features

A MnZn ferrite for use in a wide range of high and low flux density inductive designs for frequencies up to 100 kHz.
