Classification standards for capacitor ceramics
The different ceramic materials used for ceramic capacitors, or ceramics, influences the electrical characteristics of the capacitors. Using mixtures of paraelectric substances based on titanium dioxide results in very stable and linear behavior of the capacitance value within a specified temperature range and low losses at high frequencies. But these mixtures hav. There are two standards that classify commonly available dielectric materials: the International Electrotechnical Commission (IEC) and the Electronic Industries Alliance (EIA). [pdf]
FAQS about Classification standards for capacitor ceramics
What are the different types of ceramic capacitors?
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.
What are the characteristics of a Class I ceramic capacitor?
Class I ceramic capacitors are characterized by high stability, low losses, and minimal variation in capacitance over various environmental conditions. The most common example of Class I ceramic capacitors are C0G (NP0) and U2J capacitors. Here are the key characteristics of Class I ceramic capacitors, particularly C0G:
What is the difference between Class 1 and 2 ceramic capacitors?
Class 2 ceramic capacitors have a dielectric with a high permittivity and therefore a better volumetric efficiency than class 1 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.
