Ferrite planar cores for SMPs
5 June 2002
Power Electronics / Power Management
AVX offers ferrite planar cores specifically designed for use in switch mode power supply (SMPS), industrial power supply and telecom applications. Designated the low profile E core series, these cores are available in a wide range of core sizes and designs.
The low profile planar cores exhibit superior thermal and electrical characteristics and provide higher power density. Designed in a high frequency material (F2), they are formulated for minimum power loss at frequencies above 100 kHz. F2 material allows for reduced size in higher speed DC-DC converters. Additionally, the design allows for wire printing directly on a PCB, reducing manufacturing costs.
They are designed primarily for transformers and output chokes in SMPS applications, communication systems, industrial power supplies and automotive applications.
AVX provides standard E14, E18 and E22 planar cores, but can also supply ER09, ER11 and ER14.5 models. All shapes are available in several heights and with various airgaps.
