MLCCs are important passive components and were born in the 1960s. Because of its advantages such as high reliability, small size, low loss, and easy placement, it has quickly become the preferred type of capacitor in the electronics industry. With the development of various electronic industries such as household appliances, computers, network equipment, mobile phones, and [...]
1 Frequency Characteristics of Ceramic Capacitors 🍏1.1 Q value and frequency characteristics of ceramic capacitors The capacitance of the first type of ceramic 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/ultra-high-frequency capacitors are used in bad resonant circuits. High-frequency/ultra-high-frequency [...]
ceramic capacitors is a capacitor that uses ceramic materials as a medium, coats a layer of metal film on the ceramic surface, and then sinters at a high temperature as an electrode. It is usually used in high-stability oscillating loops as loops, bypass capacitors and pad capacitors. As long as the ceramic capacitor is aimed at [...]
Ceramic capacitors have a variety of uses, and they play different roles in different circuits.Typical ceramic capacitor applications are divided into four types, namely coupling, decoupling, smoothing, and filter. This will be explained in detail below,let us take a look. Coupling of ceramic capacitors When a ceramic capacitor is used for a coupling function, its DC component [...]
