Preview
Summary
IEC 62358:2026 provides standard AL values (inductance factors) and their tolerances of Pot, RM, ETD, E, EER, EP, PQ, PM, EC, EFD and low-profile gapped ferrite cores.
This edition includes the following significant technical changes with respect to the previous edition:
a) addition of AL value (inductance factor) and its tolerance for PM-cores;
b) addition of AL value (inductance factor) and its tolerance for EC-cores;
c) addition of AL value (inductance factor) and its tolerance for EFD-cores.
