The four digits following the product description provide the
largest dimension of the part in thousandths of an inch. For
toroids and similar shapes, it usually describes the outside or
major diameter of the core.
For other types of parts, it is the largest dimension specified in
the part’s description.

The first of the three digits following the dash refers to the part
thickness. A zero through nine digit refers variations in thickness
from the same tool. The second modifying digit relates to a
custom requirement (electrical testing or physical specification).
The third digit or letter describes a coating or finish.
