Chip Ceramic capacitor (MLCC) is a common electronic component used for filtering, coupling, terminal voltage stability and other functions in the circuit. It is made of ceramic materials and has the advantages of good high-frequency characteristics, small size, and high reliability. At present, the common patch Ceramic capacitor materials in the market are as follows:
X7R material
X7R material is a common patch Ceramic capacitor material with good temperature stability and dielectric constant stability. It can operate over a wide temperature range, typically from -55 ° C to+125 ° C, and some models can even reach+150 ° C. The dielectric constant of X7R material is usually between 3000 and 7000, with a high capacitance density. In addition, X7R material also has excellent voltage coefficient and withstand voltage characteristics, suitable for high-voltage applications.
X5R material
X5R material, similar to X7R material, is also a common patch Ceramic capacitor material. It has good temperature stability and dielectric constant stability, and can usually operate within the temperature range of -55 ° C to+85 ° C. The dielectric constant of X5R material is usually between 1000 and 3000, with a high capacitance density. Compared with X7R material, X5R material has slightly worse pressure resistance characteristics and is suitable for low-voltage applications.
NPO material
NPO material is a temperature compensated ceramic material, also known as COG material. It has good temperature stability and dielectric constant stability, and can operate over a wide temperature range, usually from -55 ° C to+125 ° C. The dielectric constant of NPO materials is very stable, usually 1, and is therefore widely used in circuits that require precise stability of capacitance values. In addition, NPO materials also have lower loss factors and excellent high-frequency characteristics.
Y5V material
Y5V material is a high dielectric constant ceramic material that typically operates in the temperature range of -30 ° C to+85 ° C. The dielectric constant of Y5V material is usually between 1000 and 3000, with a high capacitance density. However, the dielectric constant of Y5V material varies with temperature, so its capacitance value may vary significantly in high or low temperature environments. In addition, Y5V material also has high loss factor and poor high-frequency characteristics.
C0G material
C0G material is a temperature compensated ceramic material, also known as NP0 material. It has excellent temperature stability and dielectric constant stability, and can operate over a wide temperature range, usually from -55 ° C to+125 ° C. The dielectric constant of C0G material is very stable, usually 1, so it is widely used in circuits that require precise stability of capacitance values. In addition, C0G material also has a lower loss factor and excellent high-frequency characteristics.
To sum up, patch Ceramic capacitor materials include X7R, X5R, NPO, Y5V and C0G. They each have different characteristics and are suitable for different application scenarios. When choosing the SMD Ceramic capacitor, it is necessary to select appropriate materials according to the specific circuit requirements and working environment to ensure the performance and reliability of the circuit.
