(under the class definition) Inductor devices wherein a coil or winding of the inductor consists of a solid, unitary preformed casing which substantially completely encloses the rest of the inductor structure. A wound coil such as a toroidal or spherical coil which completely encloses another coil and/or core is excluded from this subclass and may be found in the appropriate structural subclasses below.

333, Wave Transmission Lines and Networks,
222+, for high frequency resonators of the distributed parameter type which may include a rigid external conductive casing.
334, Tuners,
41+, for resonant line tuning units wherein the tuning capacitor may be enclosed in a rigid conductive casing comprising the tuner inductor, and subclass 85 for a tuner having shielding or housing means which may be a rigid conductive casing which serves as an inductance element.
