Manganese Zinc Ferrite Materials (µi 450 – 15000)

Usually characterized by permeabilities (µ) > 1000 and saturation (Bsat) to 5300 Gauss. Typical applications include power, shielding and linear inductive components. These materials are generally used at frequencies < 10 MHz and in pulse applications into the nanosecond range and temperature range to > 200 °C.
