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.
