Product Details
Introduction
Nickel-zinc ferrite powder is a soft magnetic ferrite material mainly composed of oxides of nickel (Ni), zinc (Zn), and iron (Fe), belonging to a subcategory of spinel-type ferrites. Its core characteristics are high permeability, extremely low energy loss, and high resistivity under high-frequency magnetic fields, overcoming the significant increase in loss at high frequencies found in manganese-zinc ferrites. It is a core magnetic material for radio frequency and microwave electronic equipment.
