This table only shows common product numbers. If the EE/EEL core you need is not listed in the above table, please do not hesitate to contact us.
Le 、Ae （IEC 60205）；C1＝Le/Ae、C2＝Le/Ae²、Ve＝Le×Ae 。
Le effective path length, Ae effective area (IEC 60205); C1 = Le/Ae, C2 = Le/Ae² and Ve = Le×Ae follow from them.
Calculated from nominal dimensions per IEC 60205: C1 = ΣL/A, C2 = ΣL/A², Le = C1²/C2, Ae = C1/C2, Ve = Le×Ae; Amin = minimum cross-section; values for paired sets apply to the assembled set. ≈Wt is a reference fired-core weight — actual values vary with material and sintering, not a specification commitment; part numbers not listed have no effective-parameter data yet.
