Subclass:
RESISTORS

Description

Resistors and resistive elements used in electrical circuits and electronic devices. This subclass covers fixed and variable resistors, thermistors, varistors, and resistive films or coatings, including their construction, materials (such as carbon, wire-wound, or metal film), and manufacturing processes. Related technologies include resistor networks, resistor arrays, and hybrid resistive assemblies integrated with other components. Adjacent classes cover resistor applications within specific circuit configurations (H01L for semiconductors) and resistive heating elements designed primarily for thermal rather than electrical control purposes.
