🤚🏾 The electronic aluminum foil used in aluminum electrolytic capacitors, whether it is anode foil or cathode foil, requires the use of aluminum ingots to go through a complicated process to make foil materials. 🤚🏾 Generally, the cathode foil manufacturing process is relatively simple, as long as the continuous casting and rolling paperboard is used, and [...]
🤚🏿In practical applications, the electrolytic capacitors can be classified in more detail according to the different metal materials and shapes of the anode valve of the electrolytic capacitor, the voltage level, the packaging form, or the different electrolyte forms, the use of the capacitor and the working environment, Easy to choose when applying. ⭐️1. Classified by [...]
☀️The structural characteristics of electrolytic capacitors determine that it has the following characteristics in performance: ✨1. High specific capacitance： Since the anode of the electrolytic capacitor is manufactured by electrochemical corrosion technology or powder sintered porous block technology, it has a very high effective specific surface area. Secondly, the electrochemical anodic oxidation method is used to [...]
⭐️Paper dielectric film capacitors are the earliest film capacitors. They are wound capacitors with capacitor paper as the medium and aluminum foil as the electrode. They are available in sealed and semi-sealed structures. ⭐️The dielectric coefficient of capacitor paper is about 2.2. Because it is made of plant cellulose, it is porous, and generally contains 20% [...]
☀️The main factors affecting the dissipation factor of film capacitors are frequency, temperature, humidity and so on. ❓What is the relationship between dissipation factor and frequency? ✨If the inductive reactance Ls is not considered, for ƒ <ƒt (where ƒt is the resonant frequency), the equivalent circuit of the capacitor shows that the disipation factor tanδ is [...]
