DANSK DS/EN 61333 PDF

This International Standard specifies marking locations and a coding system of marking, especially for U and E shape ferrite cores. An alphanumerical marking printed or attached to cores reduces the risk of incorrect assembly, mixing of materials and/or mixing of gapped cores on an assembly line. The markings of the AL value or of the gap length are especially important to avoid this kind of problem and their coding system is specified in this standard.
