DEFINITION

Classification: 338/64

(under the class definition) Subject matter including a barrier or screen for shielding at least a part of the resistor device from external electrical, magnetic, or electro-magnetic fields, or for protecting parts of the device from such fields originating in another part of the

device, of for preventing the resistor device from emanating such fields or waves containing such fields.

(1) Note. A fixed resistor with a casing or housing claimed as an electrical shield or equivalent terminology is classified here, and not in subclasses 226+ below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

60, for resistors having means to reduce or eliminate capacity of the effect thereof within the resistor.

61+, for resistors having means to reduce or eliminate inductance or the effect thereof within the resistor.

266+, for resistors generally with casings or housings not limited by claimed subject matter to electric shielding. See also (1) Note above. SEE OR SEARCH CLASS

174, Electricity: Conductors and Insulators,

35+, for electrically shielded electrical conductors and insulators; or electrical shields or screens not classifiable in other main classes. See also the Search Notes under this subclass.

334, Tuners,

85, for tuners with electric and/or magnetic shielding or housing means.

336, Inductor Devices,

84+, for inductor devices with electric and/or magnetic shielding means.
