EP, EPO, EPX

TDK (Epcos)  produces 7 standard EP core shapes,  1  EPO and 3 EPX core-shapes based on  power and broadband ferrite materials. 

EP, EPX and EPO cores are typically used for transformer applications. Their cubic shape provides an excellent volume ratio to total space used and permits high PCB packing densities. The compact design and the broadband materials used (N30, T38, T57, T65 and T66) ensure low magnetic leakage, low signal distortion and excellent properties for broadband small-signal transmission (xDSL). EP cores are increasingly being used for power applications. The series EP 7 through EP 20 made of N87 for operation up to about 300 kHz is recommended.

Matching pinned and SMD coil formers suitable for automatic processing and shielding accessories (yoke, clamp or cap yoke) complete the product line.
