MULTILAYER CERAMIC CAPACITORS/AXIAL & RADIAL LEADED
Multilayer ceramic capacitors are available in a
variety of physical sizes and configurations, including
leaded devices and surface mounted chips. Leaded
styles include molded and conformally coated parts
with axial and radial leads. However, the basic
capacitor element is similar for all styles. It is called a
chip and consists of formulated dielectric materials
which have been cast into thin layers, interspersed
with metal electrodes alternately exposed on opposite
edges of the laminated structure. The entire structure is
fired at high temperature to produce a monolithic
block which provides high capacitance values in a
small physical volume. After firing, conductive
terminations are applied to opposite ends of the chip to
make contact with the exposed electrodes.
Termination materials and methods vary depending on
the intended use.
TEMPERATURE CHARACTERISTICS
Ceramic dielectric materials can be formulated with
Class III:
General purpose capacitors, suitable
a wide range of characteristics. The EIA standard for
for by-pass coupling or other applications in which
ceramic dielectric capacitors (RS-198) divides ceramic

dielectrics into the following classes:
