☀️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 [...]
The aging characteristics of the class Ⅱ of ceramic capacitors ☀️Ageing is a unique characteristic of ceramic capacitors. As the time of delivery of ceramic capacitors increases, the capacitance of the capacitor decays. The Class Ⅰ of ceramic dielectric capacitor has no aging phenomenon; the Class Ⅱ of ceramic capacitor has an aging phenomenon. ☀️The capacitance of [...]
The relationship between capacitor voltage and operating temperature ⛳️For organic films, when the temperature rises to a certain level, the film begins to soften, and the withstand voltage will be greatly reduced at this time. Therefore, organic film capacitors must not work at excessively high temperatures. If they must work at high temperatures, they must be [...]
Characterization parameters of electrolytic capacitors-Leakage Current, Rated Voltage, Capacitance Temperature Change Rate. 🔔 Today we will introduce: leakage current (I), rated voltage (U), and capacitance temperature change rate. 🔺1.1.1 Leakage current (I) 📌The leakage current of an electrolytic capacitor is used to characterize its insulation, which is equivalent to the insulation resistance parameter of other types [...]
Please check the ceramic capacitor manufacturing process: 💥Silver Paste Spraying 👉Silver Paste Spraying is one of the methods for coating electrodes in ceramic, glass, mica and other inorganic dielectric capacitors. Its working principle is through spray paint, which uses 4 to 5 atmospheres of compressed air to spray silver paste on the surface of the medium [...]
