New size for magnetic cores

29 January 2003 Passive Components

EP cores are very popular for telecom transformer designs because of their flat top for easy handling and their closed shape for excellent magnetic shielding. Up to now the EP7 core was the smallest available size in the range. For this reason, designers requiring smaller sizes had to deviate from normal practice and switch to small E cores or toroids. Ferroxcube's new EP5 design, complete with SMD bobbin and clip, satisfies the need for smaller pulse transformers. They are available in the high permeability material 3E6 for pulse transformers and in the new low harmonic distortion material 3E55 for DSL wideband applications. Even though the EP5 has half the volume of an EP7 it is suitable to build pulse transformers which comply to CCITT (G.703).
