Varistor is the abbreviation of voltage sensitive resistor, and it is a kind of non-linear resistance element. The resistance of the varistor is related to the voltage applied at both ends. When the voltage applied to the varistor is within its nominal value, the resistance of the resistor presents an infinite state, and almost no current [...]
Today is March 15, which is the annual International Consumer Rights Day. This year's theme is "Guardian Security, Smooth Consumption". It contains three meanings. One is to perform duties in accordance with the law and to build a foundation for the healthy development of the consumer market; the other is to pinpoint pain points to meet [...]
Aluminum electrolysis basically consists of positive electrode foil + oxide film (cannot exist independently of the positive electrode foil) + electrolytic paper (impregnated with electrolyte) + negative electrode foil + shell + rubber plug + lead + sleeve The first step: the corrosion of aluminum foil: increase the area by tens to hundreds of times, uneven [...]
China pays more attention to development quality rather than quantity According to a report on the German "Business Daily" website on March 6, the Chinese government has set a relatively modest target for this year's economic growth: more than 6%. Considering the current global crisis, this growth rate appears to be very high. The report said [...]
Characteristics of ceramic capacitors ① Since the dielectric material of the capacitor is Taowa, it has good heat resistance and is not easy to age. ②Porcelain dielectric capacitors can withstand acid, alkali and salt corrosion, and have good corrosion resistance. ③ The low-frequency ceramic material has a large dielectric constant, so the low-frequency ceramic capacitor has [...]
