Capacitor technical knowledge, principles and fundamentals
Multi-layer chip ceramic capacitors are the most widely used type of chip components. They are made by alternately superposing the inner electrode material and the ceramic body in multiple layers and co-firing into a whole, also known as a monolithic capacitor. With small size, high specific volume and high precision, it can be mounted on printed [...]
The feed through capacitor is a three-terminal capacitor, but compared to the conventional three-terminal capacitor, because it is directly mounted on the metal panel, its grounding inductance is smaller, almost no lead inductance, and its input and output The ends are isolated by metal plates, eliminating high-frequency coupling. These two characteristics determine the filter effect of [...]
On August 2nd, China Nonferrous Metals Industry Association organized an expert meeting on scientific and technological achievements in Kunming, Yunnan Province, and completed the "electrolytic aluminum overhaul slag" jointly completed by Zhengzhou Hongyue Environmental Protection Technology Co., Ltd., Hunan Zhongda Metallurgical Design Co., Ltd. and Zhengzhou University of Light Industry. The method of acid-free treatment and [...]
Cost increases, new capacity slows down, electrolytic aluminum stocks continue to decline On July 30, Shanghai Nonferrous Metals Network data showed that the total inventory of aluminum ingots in consumption was 1.78 million tons, down 15,000 tons from last Thursday. According to industry insiders, electrolytic aluminum inventories continue to fall, aggregate supply is limited, cost support [...]
The capacitor utilizes a surface effect with two electrode plates 1: Suppose a piece has a positive charge on it, then the other side will have a corresponding positive charge, so that an electric field is formed between the two plates, and the potential difference of the electric field is the voltage. 2: Assuming that a [...]
