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

dielectric losses, high insulation resistance and

dielectrics into the following classes:

no importance. Class III capacitors are similar to Class

II capacitors except for temperature characteristics,

which are greater than ± 15%. Class III capacitors
