Electrical capacitors; fixed, tantalum

HS v2017 Code: 853221

About electrical capacitors; fixed, tantalum

hs code 853221 covers the classification of electrical capacitors, specifically those that are fixed and made of tantalum. Capacitors are essential electronic components that store and release electrical energy, playing a crucial role in a wide range of electronic devices and circuits. The tantalum capacitor industry is a vital part of the broader electronics manufacturing sector, supporting the production of various consumer and industrial products.

Production process

Tantalum capacitors are produced through a multi-step manufacturing process. The key steps involve the formation of a tantalum anode, the application of a dielectric layer, and the addition of a cathode material. The tantalum anode is created by pressing and sintering tantalum powder, while the dielectric layer is typically made of tantalum oxide. The cathode is then added, often using a conductive polymer or other materials, to complete the capacitor structure.

Production inputs

The main inputs required for the production of hs code 853221 tantalum capacitors include high-purity tantalum powder, specialized manufacturing equipment such as sintering furnaces and coating machines, and various chemicals and materials for the dielectric and cathode layers. Additionally, the industry relies on a skilled workforce capable of operating the production equipment and maintaining quality control standards.
