AI Technical Summary

Technical Problem

Traditional circular ceramic capacitors have low material utilization, large size, and require a lot of installation space, which limits their application in compact devices.

Method used

The design features a square structure, including a square ceramic base, a diaphragm, printed electrodes, and pins, all sealed with glass sealant. The pins are electrically connected to the lower printed electrodes. Combined with conductive silver paste and stress relief holes, this enhances installation stability and capacitance performance.

Benefits of technology

While ensuring accuracy and stability, the size and weight have been reduced, the material utilization rate has been improved, it is suitable for more compact installation spaces, and processing losses and economic costs have been reduced.
