Kemet C630/C631 Multilayer ceramic capacitors/axial & radial leaded Datasheet

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.

CERAMIC CAPACITORS
Polarity: Multilayer ceramic capacitors are not polar,
and may be used with DC voltage applied in either direction.
Rated Voltage: This term refers to the maximum continuous DC working voltage permissible across the entire
operating temperature range. Multilayer ceramic capacitors
are not extremely sensitive to voltage, and brief applications
of voltage above rated will not result in immediate failure.
However, reliability will be reduced by exposure to sustained
voltages above rated.
Capacitance: The standard unit of capacitance is the
farad. For practical capacitors, it is usually expressed in
microfarads (10-6 farad), nanofarads (10-9 farad), or picofarads
(10-12 farad). Standard measurement conditions are as
follows:
Class I (up to 1,000 pF):
1MHz and 1.2 VRMS
maximum.
Class I (over 1,000 pF):
1kHz and 1.2 VRMS
maximum.
Class II:
1 kHz and 1.0 ± 0.2 VRMS.
Class III:
1 kHz and 0.5 ± 0.1 VRMS.
Like all other practical capacitors, multilayer ceramic
capacitors also have resistance and inductance. A simplified
schematic for the equivalent circuit is shown in Figure 1.

these additional properties are as follows:

ELECTRICAL CHARACTERISTICS
The fundamental electrical properties of multilayer
ceramic capacitors are as follows:
Dissipation Factor: Dissipation Factor (DF) is a measure of the losses in a capacitor under AC application. It is the
ratio of the equivalent series resistance to the capacitive reactance, and is usually expressed in percent. It is usually measured simultaneously with capacitance, and under the same
conditions. The vector diagram in Figure 2 illustrates the relationship between DF, ESR, and impedance. The reciprocal of
the dissipation factor is called the “Q”, or quality factor. For
convenience, the “Q” factor is often used for very low values
of dissipation factor. DF is sometimes called the “loss tangent”
or “tangent d”, as derived from this diagram.

Xc =

Insulation Resistance: Insulation Resistance (IR) is the
DC resistance measured across the terminals of a capacitor,
represented by the parallel resistance (Rp) shown in Figure 1.
For a given dielectric type, electrode area increases with
capacitance, resulting in a decrease in the insulation resistance. Consequently, insulation resistance is usually specified
as the “RC” (IR x C) product, in terms of ohm-farads or
megohm-microfarads. The insulation resistance for a specific
capacitance value is determined by dividing this product by
the capacitance. However, as the nominal capacitance values
become small, the insulation resistance calculated from the
RC product reaches values which are impractical.
Consequently, IR specifications usually include both a minimum RC product and a maximum limit on the IR calculated
from that value. For example, a typical IR specification might
read “1,000 megohm-microfarads or 100 gigohms, whichever
is less.”
Insulation Resistance is the measure of a capacitor to
resist the flow of DC leakage current. It is sometimes referred
to as “leakage resistance.” The DC leakage current may be
calculated by dividing the applied voltage by the insulation
resistance (Ohm’s Law).
Dielectric Withstanding Voltage: Dielectric withstanding voltage (DWV) is the peak voltage which a capacitor is
designed to withstand for short periods of time without damage. All KEMET multilayer ceramic capacitors will withstand a
test voltage of 2.5 x the rated voltage for 60 seconds.
KEMET specification limits for these characteristics at
standard measurement conditions are shown in Table 1 on
page 4. Variations in these properties caused by changing
conditions of temperature, voltage, frequency, and time are
covered in the following sections.

CERAMIC CAPACITORS
Application Notes
At higher AC voltages, both capacitance and dissipation factor
begin to decrease.
Typical curves showing the effect of applied AC and DC
voltage are shown in Figure 6 for KEMET X7R capacitors and
Figure 7 for KEMET Z5U capacitors.
Effect of Frequency: Frequency affects both capacitance and dissipation factor. Typical curves for KEMET multilayer ceramic capacitors are shown in Figures 8 and 9.
The variation of impedance with frequency is an important consideration in the application of multilayer ceramic
capacitors. Total impedance of the capacitor is the vector of the
capacitive reactance, the inductive reactance, and the ESR, as
illustrated in Figure 2. As frequency increases, the capacitive
reactance decreases. However, the series inductance (L)
shown in Figure 1 produces inductive reactance, which
increases with frequency. At some frequency, the impedance
ceases to be capacitive and becomes inductive. This point, at
the bottom of the V-shaped impedance versus frequency
curves, is the self-resonant frequency. At the self-resonant frequency, the reactance is zero, and the impedance consists of
the ESR only.
Typical impedance versus frequency curves for KEMET
multilayer ceramic capacitors are shown in Figures 10, 11, and
12. These curves apply to KEMET capacitors in chip form, without leads. Lead configuration and lead length have a significant
impact on the series inductance. The lead inductance is
approximately 10nH/inch, which is large compared to the
inductance of the chip. The effect of this additional inductance
is a decrease in the self-resonant frequency, and an increase
in impedance in the inductive region above the self-resonant
frequency.
Effect of Time: The capacitance of Class II and III
dielectrics change with time as well as with temperature, voltage and frequency. This change with time is known as “aging.”
It is caused by gradual realignment of the crystalline structure
of the ceramic dielectric material as it is cooled below its Curie
temperature, which produces a loss of capacitance with time.
The aging process is predictable and follows a logarithmic
decay. Typical aging rates for C0G, X7R, and Z5U dielectrics
are as follows:
C0G
X7R
Z5U
Effect of Temperature: Both capacitance and dissipation factor are affected by variations in temperature. The maximum capacitance change with temperature is defined by the
temperature characteristic. However, this only defines a “box”
bounded by the upper and lower operating temperatures and
the minimum and maximum capacitance values. Within this
“box”, the variation with temperature depends upon the specific dielectric formulation. Typical curves for KEMET capacitors are shown in Figures 3, 4, and 5. These figures also
include the typical change in dissipation factor for KEMET
capacitors.
Insulation resistance decreases with temperature.
Typically, the insulation resistance at maximum rated temperature is 10% of the 25°C value.
Effect of Voltage: Class I ceramic capacitors are not
affected by variations in applied AC or DC voltages. For Class
II and III ceramic capacitors, variations in voltage affect only
the capacitance and dissipation factor. The application of DC
voltage higher than 5 vdc reduces both the capacitance and
dissipation factor. The application of AC voltages up to 10-20
Vac tends to increase both capacitance and dissipation factor.
None
2.0% per decade of time
5.0% per decade of time
Typical aging curves for X7R and Z5U dielectrics are
shown in Figure 13.
The aging process is reversible. If the capacitor is heated to a temperature above its Curie point for some period of
time, de-aging will occur and the capacitor will regain the
capacitance lost during the aging process. The amount of deaging depends on both the elevated temperature and the
length of time at that temperature. Exposure to 150°C for onehalf hour or 125°C for two hours is usually sufficient to return
the capacitor to its initial value.
Because the capacitance changes rapidly immediately
after de-aging, capacitance measurements are usually delayed
for at least 10 hours after the de-aging process, which is often
referred to as the “last heat.” In addition, manufacturers utilize
the aging rates to set factory test limits which will bring the
capacitance within the specified tolerance at some future time,
to allow for customer receipt and use. Typically, the test limits
are adjusted so that the capacitance will be within the specified
tolerance after either 1,000 hours or 100 days, depending on
the manufacturer and the product type.

POWER DISSIPATION
Power dissipation has been empirically determined for
two representative KEMET series: C052 and C062. Power dissipation capability for various mounting configurations is shown
in Table 3. This table was extracted from Engineering Bulletin
F-2013, which provides a more detailed treatment of this subject.
Note that no significant difference was detected between
the two sizes in spite of a 2 to 1 surface area ratio. Due to the
materials used in the construction of multilayer ceramic capacitors, the power dissipation capability does not depend greatly
on the surface area of the capacitor body, but rather on how
well heat is conducted out of the capacitor lead wires.
Consequently, this power dissipation capability is applicable to
other leaded multilayer styles and sizes.

As shown in Table 3, the power dissipation capability of
the capacitor is very sensitive to the details of its use environment. The temperature rise due to power dissipation should not
exceed 20°C. Using that constraint, the maximum permissible
power dissipation may be calculated from the data provided in
Table 3.
It is often convenient to translate power dissipation capability into a permissible AC voltage rating. Assuming a sinusoidal wave form, the RMS “ripple voltage” may be calculated
from the following formula:
E=Zx
Where

R
RELIABILITY
A well constructed multilayer ceramic capacitor is
extremely reliable and, for all practical purposes, has an infinite life span when used within the maximum voltage and
temperature ratings. Capacitor failure may be induced by sustained operation at voltages that exceed the rated DC voltage,
voltage spikes or transients that exceed the dielectric withstanding voltage, sustained operation at temperatures above
the maximum rated temperature, or the excessive temperature rise due to power dissipation.
Failure rate is usually expressed in terms of percent per
1,000 hours or in FITS (failure per billion hours). Some
KEMET series are qualified under U.S. military established
reliability specifications MIL-PRF-20, MIL-PRF-123, MILPRF-39014, and MIL-PRF-55681. Failure rates as low as
0.001% per 1,000 hours are available for all capacitance /
voltage ratings covered by these specifications. These specifications and accompanying Qualified Products List should
be consulted for details.
For series not covered by these military specifications,
an internal testing program is maintained by KEMET Quality
Assurance. Samples from each week’s production are subjected to a 2,000 hour accelerated life test at 2 x rated voltage
and maximum rated temperature. Based on the results of
these tests, the average failure rate for all non-military series
covered by this test program is currently 0.06% per 1,000
hours at maximum rated conditions. The failure rate would be
much lower at typical use conditions. For example, using MILHDBK-217D this failure rate translates to 0.9 FITS at 50%
rated voltage and 50°C.
Current failure rate details for specific KEMET multilayer ceramic capacitor series are available on request.
MISAPPLICATION
Ceramic capacitors, like any other capacitors, may fail
if they are misapplied. Typical misapplications include exposure to excessive voltage, current or temperature. If the
dielectric layer of the capacitor is damaged by misapplication
the electrical energy of the circuit can be released as heat,
which may damage the circuit board and other components
as well.
If potential for misapplication exists, it is recommended
that precautions be taken to protect personnel and equipment
during initial application of voltage. Commonly used precautions include shielding of personnel and sensing for excessive
power drain during board testing.
E = RMS Ripple Voltage (volts)
P = Power Dissipation (watts)
Z = Impedance
R = ESR
The data necessary to make this calculation is included in
Engineering Bulletin F-2013. However, the following criteria
must be observed:
1. The temperature rise due to power dissipation
should be limited to 20°C.
2. The peak AC voltage plus the DC voltage must not
exceed the maximum working voltage of the
capacitor.
Provided that these criteria are met, multilayer ceramic
8
capacitors may be operated with AC voltage applied without
need for DC bias.
STORAGE AND HANDLING
Ceramic chip capacitors should be stored in normal
working environments. While the chips themselves are quite
robust in other environments, solderability will be degraded
by exposure to high temperatures, high humidity, corrosive
atmospheres, and long term storage. In addition, packaging
materials will be degraded by high temperature – reels may
soften or warp, and tape peel force may increase. KEMET
recommends that maximum storage temperature not exceed
40˚ C, and maximum storage humidity not exceed 70% relative humidity. In addition, temperature fluctuations should be
minimized to avoid condensation on the parts, and atmospheres should be free of chlorine and sulfur bearing compounds. For optimized solderability, chip stock should be
used promptly, preferably within 1.5 years of receipt.

CERAMIC LEADED
PACKAGING INFORMATION
Ceramic Axial
Lead Tape and Reel Packaging
KEMET offers standard reeling of Molded and Conformally
Coated Axial Leaded Ceramic Capacitors for automatic insertion
or lead forming machines per EIA specification RS-296. KEMET’s
internal specification four-digit suffix, 7200, is placed at the end of
the part number to designate tape and reel packaging, ie:
C410C104Z5U5CA7200.
Paper (50 lb.) test minimum is inserted between the layers of
capacitors wound on reels for component pitch ≤ 0.400”.
Capacitor lead length may extend only a maximum of .0625”
(1.59mm) beyond the tapes’ edges. Capacitors are centered in a
row between the two tapes and will deviate only ± 0.031
(0.79mm) from the row center. A minimum of 36” (91.5 cm) leader
tape is provided at each end of the reel capacitors. Universal
splicing clips are used to connect the tape. Standard reel
quantities are shown on page 48.
