Electrical capacitors

CPC v2.1 Code: 4711

About electrical capacitors

cpc code 4711 covers the production of electrical capacitors, a critical component in a wide range of electronic devices and systems. Capacitors are essential for filtering, timing, and power supply regulation in everything from consumer electronics to industrial machinery. This industry plays a vital role in supporting the broader electronics and electrical equipment manufacturing sectors, which are key drivers of technological innovation and economic growth.

Production process

The main production techniques for electrical capacitors involve the precise assembly of thin layers of conductive and insulating materials. This typically includes winding or stacking thin metal foils or films with a dielectric material in between, then encasing the assembly in a protective housing. Advanced capacitor manufacturing may also utilize specialized coating, etching, and vacuum deposition processes to achieve desired electrical properties and performance characteristics.

Production inputs

The primary inputs for the electrical capacitor industry include raw materials such as metal foils (e.g., aluminum, tantalum, ceramic), dielectric films (e.g., polypropylene, polyester, ceramic), and housing components (e.g., plastic, metal). Specialized manufacturing equipment, including winding machines, coating systems, and testing apparatus, are also essential inputs for this industry. Additionally, the industry relies on a skilled workforce capable of precise assembly and quality control procedures.

Production outputs

Electrical capacitors produced under cpc code 4711 are consumed by a wide range of industries, including 4621 Manufacture of electronic components and boards, 4622 Manufacture of computers and peripheral equipment, and 4623 Manufacture of communication equipment. Capacitors are critical components in a variety of electronic devices, such as smartphones, televisions, industrial automation systems, and power supplies.
