Class II ceramic capacitors have a dielectric with a high permittivity and therefore a better volumetric efficiency than class I capacitors, but lower accuracy and stability. The ceramic dielectric is characterized by a nonlinear change of capacitance over the temperature range. The capacitance value also depends on the applied voltage. They are suitable for bypass, coupling and decoupling applications or for frequency discriminating circuits where low losses and high stability of capacitance are less important. They typically exhibit microphony.
However, the high permittivity supports high capacitance values in small devices. Class II capacitors are significantly smaller than class I devices at the equal rated capacitance and voltage. They are suitable for applications that require the capacitor to maintain only a minimum value of capacitance, for example, buffering and filtering in power supplies and coupling and decoupling of electric signals.
