Color of ceramic capacitors

Porcelain capacitors are capacitors made of ceramics with a metal film coated on the surface of the ceramics and then sintered at high temperature. It is usually used in high-stability oscillation circuits as circuits, bypass capacitors, and pad capacitors. Ceramic capacitors are widely used in blue and turquoise ceramic capacitors. Blue ceramic capacitors are encapsulated with epoxy resin, so they have good moisture resistance and strong electrical resistance. The ocher ceramic capacitor is made of phenolic resin, so it is easy to love tide and has low voltage resistance.

Ceramic capacitors are divided according to ceramic dielectrics:

1. Class dielectrics (NP0, C0G);

2. Class dielectrics (X7R, 2X1);

3. Class dielectric (Y5V, 2F4);

Advantages: stable, good insulation, high voltage resistance;

Disadvantages: relatively small capacity;

effect:

1. MLCC (Class 1)-Miniaturization, high frequency, ultra-low loss, low ESR, high stability, high withstand voltage, high insulation, high reliability, non-polarity, low capacitance, low cost, high temperature resistance, main applications In high-frequency circuits.

2. MLCC (Type 2)-Miniaturization, high specific volume, medium and high voltage, non-polar, high reliability, high temperature resistance, low ESR, low cost, mainly used for DC blocking, coupling, bypass and Used for filtering capacitors.

Know the type you need when purchasing ceramic capacitors and avoid mistakes. If you are not sure which type of capacitor you are suitable for, you can consult a regular ceramic capacitor manufacturer to provide advice and reference.
