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 [...]
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 [...]
Polystyrene capacitors belong to the category of organic film capacitors, and their dielectric is polystyrene film, and there are two types of electrodes: metal foil type and metal film type. Since the polystyrene film is a heat-shrinkable oriented film, the wound capacitor can be made into a non-sealed structure by the method of self-heat shrinkage polymerization. [...]
Polypropylene film capacitors belong to the category of organic film capacitors. Its dielectric is polypropylene film. There are two types of electrodes: metal sink type and metal film type. The coiled capacitor core is encapsulated with epoxy resin or packed into plastic and metal casings. In the package. Polypropylene capacitors made with metal film electrodes are [...]
In electronic components, we often consider some products. Is it better to choose a patch or a plug-in electrolytic capacitor? How to choose? How to choose electronic components that are more suitable for us according to the development of the market? Let's talk about the fundamental difference between chip electrolytic capacitors and plug-in electrolytic capacitors. What [...]
