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.
