General Description  
Basic Construction – A multilayer ceramic (MLC) capaci-  
tor is a monolithic block of ceramic containing two sets of  
offset, interleaved planar electrodes that extend to two  
opposite surfaces of the ceramic dielectric. This simple  
structure requires a considerable amount of sophistication,  
both in material and manufacture, to produce it in the quality  
and quantities needed in today’s electronic equipment.

Multilayer Ceramic Capacitor

Formulations – Multilayer ceramic capacitors are available  
in both Class 1 and Class 2 formulations. Temperature  
compensating formulation are Class 1 and temperature  
stable and general application formulations are classified  
as Class 2.  
Class 2 – EIA Class 2 capacitors typically are based on the  
chemistry of barium titanate and provide a wide range of  
capacitance values and temperature stability. The most  
commonly used Class 2 dielectrics are X7R and Y5V. The  
X7R provides intermediate capacitance values which vary  
only 15ꢀ over the temperature range of -55°C to 125°C. It  
finds applications where stability over a wide temperature  
range is required.  
Class 1 – Class 1 capacitors or temperature compensating  
capacitors are usually made from mixtures of titanates  
where barium titanate is normally not a major part of the  
mix. They have predictable temperature coefficients and  
in general, do not have an aging characteristic. Thus they  
are the most stable capacitor available. The most popular  
Class 1 multilayer ceramic capacitors are C0G (NP0)  
temperature compensating capacitors (negative-positive  
0 ppm/°C).  
The Y5V provides the highest capacitance values and is  
used in applications where limited temperature changes are  
expected. The capacitance value for Y5V can vary from  
22ꢀ to -82ꢀ over the -30°C to 85°C temperature range.  
The Z5U dielectric is between X7R and Y5V in both stability  
and capacitance range.  
All Class 2 capacitors vary in capacitance value under the  
influence of temperature, operating voltage (both AC and  
DC), and frequency. For additional information on perfor-  
mance changes with operating conditions, consult AVX’s  
software, SpiCap.
