ET SERIES Introduce of ET core Ferrite cores consisted of stacks of laminations; patterns cut or stamped out of thin sheets of electrical steels. Most applications required a lamination pattern (or patterns) that would form a closed magnetic loop when assembled together. The shape of ET core is closed magnetic loop, which unlike other E shape cores. When apply with electronic parts, the ET core possess high efficiency, low leakage inductance. Application of ET core Mn-Zn high permeability ET cores can be widely used as Balance cores, cable cores, Pulse Transformer core to application in Electronic parts for Green Illumination Project and Common-Mode Choke, etc. Type Dimensions(mm) A B C D E F ET20 20.1±0.5 20.1±0.5 4.0±0.2 4.4±0.2 2.0±0.2 2.0±0.2 ET24 24.2±0.5 24.2±0.5 4.0±0.2 4.0±0.3 2.4±0.2 2.0±0.2 ET28 28.7±0.5 28.7±0.5 5.0±0.3 5.0±0.3 2.9±0.2 2.9±0.2 ET35 53.3±0.6 35.3±0.6 7.5±0.3 7.5±0.3 4.0±0.2 4.0±0.2 together.
