COG/NPO MLCC for general use belongs to Class one high-frequency capacitor. Its capacitance is very stable, almost not changeable along with the temperature, voltage and time and quite suitable for use in high frequency circuits.

X7R MLCC for general use belongs to Class two low-frequency capacitor. Its capacitance is stable and suitable for all kinds of filter and coupling circuits.

Y5V MLCC for general use belongs to Class two low frequency capacitor. Its capacitance will change obviously along with the temperature, voltage and time and suitable for all kinds of filter circuits.

Z5U MLCC for general use belongs to Class two low frequency capacitor. Its capacitance stability is between that X7R and Y5V and suitable for all kinds of filter and coupling circuits.
