EFD Cores
EFD (Economical Flat Design) cores were developed to meet the increasing demand for low profile components in power transformer design. A combination of very low height and excellent throughput power, when compared to other cores of a similar height, make these cores ideal where space considerations are a priority. EFD Cores are available in a range of sizes and materials as per IEC 62317-14 together with their associated coil formers and clips.
