Higher ceramic capacitor values vary from 1 pF to about 1 µF, with a working ceramic capacitor voltage rating of up to a few thousand volts. Typical film capacitors have capacitances ranging from below 1 nF to 30 µF. They can be made in voltage ratings as low as 50 V, up to above 2 kV. Better DF and Q values.
Ceramic capacitors are divided into two application classes: Class 1 ceramic capacitors offer high stability and low losses for resonant circuit applications. Class 2 ceramic capacitors offer high volumetric efficiency for buffer, by-pass, and coupling applications.
These are some limitations of ceramic capacitors: They offer less capacitance value to a few microfarads. The dielectric in them can be damaged over high voltages. They may have voltage-dependent capacitance changes. Due to the construction using a ceramic material, there is a risk of cracking or damage in case of mechanical loss.
Ceramic capacitors have several properties. They possess a high dielectric constant (K), which allows them to provide a high capacitance value even in small sizes. However, they lack in accuracy and stability compared to Class II ceramic capacitors.
Small capacitance values can withstand voltages as large as 1 kV. Depending on temperature range, temperature drift and tolerance, ceramic capacitors have two active classes: Class 1 and Class 2.
