ELP-Cores by Epcos.Epcos Company produces 8 standard sizes of ferrite cores with ELP configuration. The minimum size is ELP14/3.5/5, the maximum size is ELP64/10/50.ELP ferrite cores are designed to produce the compact low-profile transformers and chokes with coils made in the form of tracks on a multilayer printed circuit board or (for high-power applications) in the form of cut copper tape from insulated layers.To make the structure of a transformer or a choke on a multilayer printed circuit windings on ferrite ELP cores considerably decrease the size and weight of wire-rap products, lower height compared to similar conventional ferrite transformers.ELP cores are used primarily in DC/DC and AC/DC converters operating at a frequency of 1 MHz.Transformers based on ferrite ELP cores are:Reliable as labor errors in winding and mounting of transformers are excluded.Low-cost at large scale production.They have higher life associated with improved heat dissipation and design reliability.They have less parasitic parameters, leakage inductance in particular.
