Class Information
Number: 336/234
Name: Inductor devices > Core (e.g., compressed powder) > Laminated type (includes bundles of rods or wires)
Description: Inductor devices having a core or magnetic body comprising superimposed bundles or layers of magnetic material in the form of sheets, rods, or wires. Single sheets, punchings, rods or wires which have such configuration that they are of no utility except in building up a core for use in an inductor device falling within the class definition are classified in this subclass.
