Frequency Characteristics of Ceramic Capacitor

👇1. Q value and frequency characteristics of ceramic capacitor ⭐️The capacitance of the class Ⅰ of ceramic dielectric capacitors (such as COG) is substantially invariant with frequency over the entire usable frequency range. Q value and resonant frequency are important indicators when high-frequency/super-frequency capacitors are used in bad resonant circuits. High-frequency/ultra-high-frequency capacitors with excellent performance have [...]

Technical specification for electrode aluminum foil for electrolytic capacitors

🎇Low purity aluminum foil is used for the negative electrode. If the aluminum component does not reach the purity of 99.9%, based on cost considerations, it can still be used for cathode aluminum foil, because the purity of the cathode aluminum foil only needs to reach the level that it will not be corroded by the [...]
