Analysis of Common Capacitors (I)

Nowadays, with the booming of electronic information technology, new digital electronic products are being introduced at a faster rate, and the production and consumption of electronic products such as flat-panel televisions, notebook computers, and digital cameras continues to increase, which also encourages the rapid development of the capacitor industry.

Next, Xiao Bian brings everyone to discuss and analyze the various key capacitors:

1. Porcelain dielectric capacitors use a ceramic material as a medium, and are often coated with a common coating of various colors on the surface of the ceramic dielectric capacitor, and the electrodes are covered with silver on a ceramic chip. This kind of capacitor consumes little, has high stability and high temperature and high voltage resistance. Capacity range: 1PF~0.1UF; rated working voltage: 63~630V; application frequency: 50~3000MHz; leakage resistance: more than 10KMΩ.

2, polyester capacitors main features: small size, large capacity, heat and humidity, poor stability. Application occasions: occasions with low requirement for stability and loss Capacity range: 40 PF~4 UF; rated working voltage: 63~630V.
