DEFINITION

Classification: 338/279

(under the class definition) Subject matter wherein the resistance element constitutes an elongated continuous flat ribbon, strip, or tape of uniform cross-sectional dimensions and integral over its length between terminals, the element being bent or curved along its flat sides between terminals into a particular configuration while retaining the ribbon-like characteristic.

(1) Note. In this subclass the flat portion of the ribbon is bent or curved. The bend on the flat sides may be transverse or oblique to the length of ribbon. An edgewise bend or curve as may occur in an edgewise wound helix in a zigzag grid resistance element is not classified here, but in such subclasses as 278 and 283+.

208, for mesh, woven, or braided resistors.

212, for flexible or folding tape resistors.

278, for a resistor whose element is helical and formed as an edgewise coiled strip. See also (1) Note above and under subclass 278.

297, for a resistor whose element is a flat helix or winding. 301, for a resistor whose element is coiled on a flat or ribbon base.
