The national standard stipulates that the vacuum capacitor model designation code is composed of the first letter (capital) of the Chinese pinyin except for the capacitor represented by C. Take ceramic vacuum capacitors as an example:

A vacuum capacitor is a capacitor with vacuum as its medium. The electrode group of this capacitor is a group of concentric cylindrical electrodes formed by extending high-conductivity oxygen-free copper strips through a set of high-precision molds one by one and sealed in a vacuum container. Theref......

The simplest capacitor consists of plates at both ends and an insulating dielectric (including air) in the middle. When energized, the plate is charged, creating a voltage (potential difference), but because of the insulating material in the middle, so the entire capacitor is not conductive. However......

A common hydrogen thyratron is a gas-filled triode: anode, grid, and cathode. The anode is a flat disc, separated by a fine mesh made of fine tungsten wire or nickel wire; 2~3 cm below the anode is a control grid, which is similar to a lining, and the round hole on the top is formed by a grid. Cover......

In high-frequency heating equipment, the oscillating electron tube is a precious device, which must be paid attention to in use and maintenance. The following issues will be introduced.

Magnetrons are characterized by high power, high efficiency, low operating voltage, small size, light weight and low cost. The magnetron is mainly composed of...
