H03 ELECTRONIC CIRCUITRY
Classification Context
- Section:
- ELECTRICITY
- Class:
- ELECTRONIC CIRCUITRY
Description
H03 encompasses the design, construction, and operation of electronic circuits and circuit components that process, generate, amplify, or control electrical signals. This class covers fundamental circuit elements including resistors, capacitors, inductors, transformers, and semiconductor devices, as well as complete circuit assemblies for applications such as amplification, oscillation, modulation, and switching. The classification includes circuits for signal processing, power conversion, and control functions across a broad range of frequencies and power levels. H03 excludes telecommunications systems and specific applications (covered in other H-series classes) but forms the foundational technology underlying most electronic devices and systems.
