This table only shows common product numbers. If the UR core you need is not listed in the above table, please do not hesitate to contact us.
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.
