EE Cores

EE Cores were one of the first ferrite cores to be manufactured, being derived from their respective iron lamination size. Having rectangular limbs they are relatively easy to manufacture and as such a vast range exists in the marketplace. Magdev's range reflects a selection of cores that have become, over many years, worldwide standards through continued use. E cores are particularly suitable for power transformers and filters at low frequencies. They are not suitable in high frequency applications as the rectangular centre limb leads to higher leakage inductance and winding resistance. EE cores are available in a range of sizes and materials as per IEC 62317-8.
