EER Cores EER CORES EER cores are an economical choice for transformers and inductors. The round centerpost offers the advantage of a shorter winding path length than the winding around a square centerpost of equal area. Hardware accessories are available. Differential inductors and power transformers are typical applications of Magnetics EER cores.
