IEC 62358:2012 provides standard AL values (inductance factors) and their tolerances of Pot, RM, ETD, E, EER, EP, PQ and low-profile gapped ferrite cores. This edition includes the following significant technical changes with respect to the previous editions: a) addition of AL value (inductance factor) and its tolerance for PQ-cores; b) addition of AL value (inductance factor) and its tolerance for EFD-cores; c) addition of AL value (inductance factor) and its tolerance for Low-profile ER-I-cores; d) addition of AL value (inductance factor) and its tolerance for Low-profile ER-cores (ER9,5 x 2,5 x 5, ER11 x 2,5 x 6, ER14,5 x 3 x 7 ferrite cores are same as the previous edition); e) addition of AL value (inductance factor) and its tolerance for Low-profile PQ-I-cores.
