283  DF  ZIGZAG OR SINUOUS RESISTANCE ELEMENT {10}
293.~ Planar


DEFINITION

Classification: 338/293

(under subclass 283) Subject matter wherein the resistance element is flat in one dimension to lie substantially in one plane.

(1) Note. A resistance element having a flat surface is not necessarily classified in the subclass. For classification here the overall shape must be flat or planar.

SEE OR SEARCH THIS CLASS, SUBCLASS:

212, for flexible or folding resistors formed as a sheet.

254, for a resistor whose flattened element is embedded between flat layers.

279+, for resistors formed as bent ribbons. 287+, for a compound or multiple zigzag type resistor whose element has a planar shape.

293, for zigzag or sinuous resistors whose elements extend through openings or slots in a support or frame and are planar.

314, for a resistor whose element and base are formed in layers.

333, for resistors of a particular configuration not classified above.
