MULTILAYER CERAMIC CAPACITORS/AXIAL

& RADIAL LEADED

Multilayer ceramic capacitors are available in a

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.

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

TEMPERATURE CHARACTERISTICS

Ceramic dielectric materials can be formulated with

a wide range of characteristics. The EIA standard for

ceramic dielectric capacitors (RS-198) divides ceramic

dielectrics into the following classes:

Class III: General purpose capacitors, suitable

for by-pass coupling or other applications in which

dielectric losses, high insulation resistance and

stability of capacitance characteristics are of little or

no importance. Class III capacitors are similar to Class

II capacitors except for temperature characteristics,

Class I: Temperature compensating capacitors,

suitable for resonant circuit application or other appli-

cations where high Q and stability of capacitance char-

acteristics are required. Class I capacitors have

predictable temperature coefficients and are not

affected by voltage, frequency or time. They are made

from materials which are not ferro-electric, yielding

superior stability but low volumetric efficiency. Class I

capacitors are the most stable type available, but have

the lowest volumetric efficiency.

which are greater than

15%. Class III capacitors

have the highest volumetric efficiency and poorest

stability of any type.

KEMET leaded ceramic capacitors are offered in

the three most popular temperature characteristics:

C0G: Class I, with a temperature coefficient of 0

30 ppm per degree C over an operating

temperature range of - 55°C to + 125°C (Also

known as “NP0”).

Class II: Stable capacitors, suitable for bypass

or coupling applications or frequency discriminating

circuits where Q and stability of capacitance char-

acteristics are not of major importance. Class II

capacitors have temperature characteristics of 15%

or less. They are made from materials which are

ferro-electric, yielding higher volumetric efficiency but

less stability. Class II capacitors are affected by

temperature, voltage, frequency and time.

X7R: Class II, with a maximum capacitance

change of 15% over an operating temperature

range of - 55°C to + 125°C.

Z5U: Class III, with a maximum capacitance

change of + 22% - 56% over an operating tem-

perature range of + 10°C to + 85°C.

Specified electrical limits for these three temperature

characteristics are shown in Table 1.
