Multilayer Chip Ceramic Capacitor (MLCC) is abbreviated as a chip capacitor. It is a type of capacitor formed by laminating and co firing multiple layers of ceramic membranes with printed metal electrodes to form a single stone structure, and then coating two ends with a layer of metal through immersion coating, sintering, and electroplating. Its external image is a small stone block, so it is also known as a single stone capacitor. It is one of the important passive electronic components (passive components).
※ High frequency category: Capacitors made of this type of dielectric material are Class I capacitors, including general-purpose high-frequency capacitorsCOGCOHCapacitors and temperature compensated high-frequencyHGLGPHRHSHTHUJSLCapacitors. amongCOGCOHCapacitors have the most stable electrical performance, almost not changing with temperature, voltage, and time. They are suitable for high-frequency circuits with low losses and high stability requirements,HGLGPHRHSHTHUJSLThe capacity of capacitors varies with temperature and is suitable for low loss, temperature compensated circuits.
※X7RX5RX7SX6SCapacitors made of this type of dielectric material are Class II capacitors with high dielectric constant, higher capacity than Class I capacitors, and more stable temperature characteristics. They are suitable for circuits with a wide range of capacity and low stability requirements, such as isolation, coupling, bypass, frequency discrimination, etc.
※Y5VCapacitors made of this type of dielectric material are Class II capacitors, which have the highest dielectric constant among all capacitors. However, their capacity stability is poor and they are sensitive to temperature, voltage, and other conditions. They are suitable for circuits that require high capacity and have little temperature change.
※Z5UCapacitors made of this type of dielectric material are Class II capacitors with temperature characteristics betweenX7RandY5VDue to poor capacity stability and sensitivity to temperature, voltage, and other conditions, it is suitable for circuits that require large capacity, use temperature ranges close to room temperature for bypass, coupling, and low DC bias.
