3E12 Datasheet, PDF (6/8 Pages) Ferroxcube International Holding B.V. – Tight tolerance, increased impedance, extended bandwidth, enhanced performance in EMC.

A selection of raw materials and optimum process control have enabled Ferroxcube to offer the highest
permeability on ferrite toroids for EMI suppression and wideband transformers. 3E12 reaches 12k on
final product (there is no difference between material and product specification) in a complete product
range up to large sizes.This improved performance results in several benefits for the inductor:
─ The possibility of reducing the size of the component keeping the same inductance and turns,
resulting in smaller footprint and reduced Rdc (shorter turns)
─ Keeping the same size, reducing the number of turns to reach the same inductance, resulting in
a lower winding cost and Rdc (less turns)
─ Improved performance: higher permeability leads to better coupling between windings.
