SMM network news: Since November, Taiwan's aluminum electrolytic capacitor company shares have soared, leading Lilong Electronics rose 25.96%, other companies Shan State, Zhibao, Jinshan Electric, Kaimei rose 34.42%, 85.57%, 25.88 %, 127.06%; Upstream electrode foil manufacturer Lidun gained 70.74%.

The overall decline in the color plate, including lithium batteries, aluminum and precious metals sector gains top, tin, rare earth and other sectors fell more. In terms of prices, copper and aluminum in the base metals have risen, and in the case of small metals, lanthanum oxides and other types ha

Capacitors are one of the three major passive electronic components (resistors, capacitors, and inductors). They occupy an important position in the electronic components industry and are an essential basic electronic component in electronic circuits. Among the components, capacitors are the most wi

Industry technology status analysis: 1. The number of industry patent applicationsJudging from the trend of changes in the total number of patent applications for aluminum electrolytic capacitors in China, before 2005, China’s patented aluminum electrolytic capacitors had a relatively small number o

Industry definition and classification:　　Aluminum electrolytic capacitors are made of aluminum cylinders, which are filled with liquid electrolyte and inserted into a capacitor made of bent aluminum strip as positive electrode.　　In the electronic components used by the whole machine, the capacitor i

Polar electrolytic capacitors usually play the role of power filtering, decoupling, signal coupling, time constant setting, and DC in the power circuit or in the middle frequency and low frequency circuits. Generally, it can not be used for AC power circuit. When using the filter capacitor in the DC

2. Reliability application of electrolytic capacitorReduce the working voltage properly.Reducing the working voltage of electrolytic capacitors is the most effective way to extend the service life of capacitors and improve reliability. Because the failure rate of electrolytic capacitor is directly p

Capacitors are generally made up of two conductors which are close to and insulated from each other. They are indispensable basic components for military electronic equipment. Electrolytic capacitors occupy a large proportion in military electronic products, and their reliability plays a vital role

The common failures of electrolytic capacitors include reduction of capacity, disappearance of capacity, breakdown of short circuit and leakage of electricity. The change of capacity is caused by the gradual drying of electrolytes in the process of the use or placement of electrolytic capacitors, an

The failure, complete leakage or pulping caused by the disappearance of electrolytic capacitor capacity is the most difficult to distinguish and maintain after the failure of the capacitor in the power supply, because the measurement of capacitance devices, using the multimeter to test all normal, b
