High-voltage smd capacitor materials: COG NPO X7R X5R Y5V

NPO (COG) smd capacitor are classified as Class I high-frequency capacitor. Their capacitance is stable and does not change with changes in ambient temperature, voltage and time, and is suitable for high-frequency electronic circuits.

The smd capacitor made of X5R/X7R are classified as type II low-frequency capacitor, their capacitance is relatively stable, and they are relatively sensitive to changes in ambient temperature, voltage and time.

SMD capacitor made of Y5V material belong to Type II low-frequency capacitor, and their capacitance varies greatly by the environment, temperature, voltage and time.
