Description

technical field

[0001] The invention belongs to the technical field of ceramic capacitors, in particular to the preparation technology of tubular ceramic capacitors. Background technique

[0002] As we all know, ceramic capacitors are basic electronic components with a wide range of applications and a large amount. According to statistics, the consumption of ceramic capacitors accounts for more than 80% of the consumption of various capacitors. Ceramic capacitors mainly perform coupling, DC blocking, bypass, filtering, energy storage and other functions in electronic circuits, and can also be combined with other electronic components to form an oscillation circuit to perform tasks such as signal transmission, reception, and processing. With the rapid expansion of the application field of electronic equipment, various electromagnetic interference problems caused by natural or human factors have become increasingly prominent. At present, the main ways to suppress electromagn...
