1 Application of large-capacity ceramic capacitors in general bypass 1.1 The role of bypass capacitors 🍏Bypass capacitors are usually connected in parallel across the power supply of a circuit unit (such as an IC) to reduce the power supply as much as possible over the entire operating frequency band or the frequency band where the circuit [...]
Different from other chip components, use of multilayer ceramic capacitors may be damaged due to large stress due to the thin internal electrodes and dielectrics, and the dielectric is very brittle: the combination of internal electrodes and terminal electrodes use of multilayer ceramic capacitors is also relatively Fragile. Therefore, relevant precautions should be observed when soldering [...]
🌕This article is about the failure analysis of ceramic capacitors, which may fail in different environments. 1.Influence of humidity on deterioration of electrical parameters 🌝When the temperature in the lost air is too high, the water film condenses on the surface of the capacitor shell, which can reduce the surface insulation resistance of the capacitor. In [...]
🔆With the continuous advancement of ceramic capacitor manufacturing technology, various new Types of Ceramic Capacitors have appeared. There are mainly multilayer ceramic capacitors, large size multilayer ceramic capacitors, flexible terminal ceramic capacitors, open circuit ceramic capacitors, feedthrough capacitors, chip feedthrough capacitors, balanced wire feedthrough capacitors, large capacitance ceramic capacitors, etc. 🍒Multilayer Ceramic Capacitors Multilayer ceramic capacitors [...]
👇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 [...]
