Description
H01G encompasses electrolytic capacitors and related electrolytic devices designed for energy storage and signal processing applications. The class covers capacitor construction, materials, and designs including aluminum, tantalum, and other electrolytic systems, as well as electrolytic rectifiers, detectors, and switching devices that rely on electrolytic phenomena. It also includes light-sensitive and temperature-sensitive devices utilizing electrolytic principles for sensing applications. Related non-electrolytic capacitors, conventional rectifier diodes, and discrete transistor switching devices are classified elsewhere in the H01 section.
