Nickel Zinc Ferrite Materials (µi 7.5 – 2100)

Characterized by permeabilities (µi) < 2500 and high resistivity (several orders of magnitude greater than MnZn) it is the ideal material for high temperature applications operating from 1-2 MHz to several hundred MHz. Typical applications include broadband RF and transmission line coupled transformers, pulse power devices where pulse shaping and fast switching (e.g. < 10 nanoseconds) is required and for general inductive devices or EMI suppression in the MHz spectrum.
