The ferrite core is composed of iron oxide (Fe2O3) and one or more other metals (such as manganese, zinc, nickel, magnesium) oxides or carbonate compounds. Ferrite raw materials are pressed, and then passed through Sintered at a high temperature and finally machined to produce a finished magnetic core that meets the needs of the application. Compared with other types of magnetic materials, ferrite has the advantages of high magnetic permeability and high resistance over a wide frequency range and small eddy current loss.

We supply following series soft ferrite cores, which are used in switch mode power supplies (SMPS), radio frequency (RF) transformers, common mode choke inductors, filters and chokes.

EFD cores

I. Features: miniaturization of transformers; horizontal installation can reduce height, with multiple outputs, dense mounting.

II. Applications: various low-power switching power supply transformers, chokes, etc.

III. Size: EFD10 EFD12 EFD17 EFD20 EFD20L EFD25 EFD30 EFD50

RM cores

II. Applications:carrier frequency inductor, power conversion transformer, auxiliary power transformer.

III. Size:RM4 RM5 RM6 RM7 RM8 RM10 RM12 RM14

PQ cores

I. Features: most suitable design shape, reducing the volume of the component during installation; meet safety requirements.

II. Applications:switching moce power supply transformers, choke coils.

III. Size:PQ20 PQ26 PQ32 PQ35 PQ40 PQ50

ER / EC / EER / ETD cores

I. Features:The cross section of the core of the magnetic core is round, which is convenient for winding; the winding area is increased, and high power switching transformer can be designed.

II. Applications:Suitable for various power forms such as single-ended flyback, forward push-pull, half-bridge, full-bridge; home appliances, communications, lighting, office automation, satellite TV receiving systems, military products and other industries.

III. Size:ER28 ER30 ER35 ER39 ER40 ER42 EC52 EC70 EC90 EC120

EE / EF cores
