EP Cores

Bunting Magnetics Europe > Soft Magnetics > Soft Ferrites > Components > EP Cores
EP Cores have a particularly compact, low profile shape and offer excellent shielding from adjacent cores due to the winding being almost completely surrounded by the ferrite core. This allows for high packing densities on printed circuit boards. Originally designed for broadband, small power transformers and signal transmission applications, the cores are well suited for the demanding properties required from modern electronic components.

EP Cores are available in a range of sizes and materials as per IEC623117-5.
