EE/EF Type Ferrite Cores Low Loss High Frequency Mn-Zn Material for Transformers and Inductors

Product Description

The EE/EF type ferrite core is manufactured using manganese-zinc (Mn-Zn) material. It offers low loss and high-frequency characteristics, specifically designed for transformer and inductor applications. The product offers high saturation flux density, wide inductance range, high current capacity, and low leakage flux. Low DCR effectively reduces power loss. Good noise control ensures stable system operation. The compact size delivers high current output with excellent choking performance. Multiple material grades are available to meet different frequency requirements. It is widely used in transformers, induction heating, inverter welders, electroplating power supplies, and ozone generators.

FAQ

Q: What is the difference between EE-type and EF-type cores?

A: EE-type cores have symmetrical side legs with a square or round centre leg cross-section. They offer good magnetic symmetry and are suitable for conventional transformers and inductors. EF-type cores (Economical Flat) are flat and cost-effective designs with more compact dimensions, suitable for high-density PCB mounting and low-profile applications.

Q: What are the characteristics of manganese-zinc (Mn-Zn) ferrite compared to nickel-zinc (Ni-Zn)?

A: Manganese-zinc ferrite offers high permeability, high saturation flux density, and low cost, suitable for low to medium frequency (≤1MHz) high-power transformer and inductor applications. Nickel-zinc ferrite offers high resistivity, suitable for high-frequency (>1MHz) EMI suppression and RF applications. Selection should be based on the operating frequency.

Q: What core series are available for this product?

A: Multiple core series are available, including EI, EE/EF, EER/ETD, UU, UYF, EP, RM, PM, PQ, ET/FT, and T. These cover applications from signal transformers to high-power switching power supplies.
