Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as CRGO steel in widths under 300mm before lamination
Primary steel products precede transformer part classification.
If specifically for cores of fluorescent lamp ballasts
Ballast transformer cores have dedicated statistical suffixes.
If sold as complete inductors rather than transformer cores
Finished inductors shift from parts to complete machines.
