Capacitor technical knowledge, principles and fundamentals
MLCC has undergone inventory adjustment for nearly one year, and the terminal inventory is in good condition. Despite the impact of the Sino-US trade war, the peak season of the electronics industry is not as good as in previous years. However, new 5G communications and smart mobile phones are on the market, and demand for some [...]
Construction of electrolytic capacitor Etching The anode and cathode metal foils are made of high-purity, very thin aluminum foil of only 0.02-0.1 mm. In order to increase the disk area and capacitance, the increase in surface area in contact with the electrolyte is achieved by etching the metal foil to dissolve the aluminum. The surface of [...]
Japanese brand aluminum electrolytic capacitor Guimigong recently announced last quarter's earnings report: due to trade friction, resulting in reduced demand for aluminum electrolytic capacitors, the revenue of the company's capacitor division decreased 21% from the same period last year to 27.038 billion yen, operating loss It was 1.134 billion yen. The revenue of other business units [...]
Engaged in the electronics industry, there is an indescribable feeling for all kinds of electronic components. For engineers engaged in the electronics industry, electronic components are like the daily rice imported by people. They need to be touched every day, and they need to be used every day. Yes, but in fact, many engineers inside the [...]
Guoju capacitor 1. According to the structure, there are three categories: fixed capacitor, variable capacitor and trimmer capacitor. 2. Classification by electrolyte: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, electric heating capacitors and air dielectric capacitors. 3, according to the use of: high frequency bypass, low frequency bypass, filtering, tuning, high frequency coupling, low frequency coupling, [...]
