3E10 Datasheet, PDF (4/8 Pages) Ferroxcube International Holding B.V. – Tight tolerance, increased impedance, extended bandwidth, enhanced performance in EMC.

3E10 is a high permeability material optimized for wideband transformers as well as in EMI-
suppression filters, the base material is MnZn. It achieves the tightest tolerance in your final
products (only 20%), so winding and potting operations have less impact on the permeability. This
means better control of the final characteristics of the component in your specific application.
3E10 is the choice when looking for a robust manufacturing process and maximum frequency
stability. Extensive material research at Ferroxcube has lead to the improvement in permeability
stability with frequency, which in turn creates reduced magnetic losses and higher common mode
impedance over a wider frequency range.
