Introduction — The following section is devoted to general
information of assistance in the application of T240 Series
capacitors. Space does not permit a complete discussion of
all technical aspects, and further information on specific
problems may be obtained through KEMET sales represen-
tatives.
Capacitance — The nominal values listed in Table I con-
forms to accepted industry practice; intermediate values may
be produced on special order. Standard tolerances are
± 20%, ± 10%, and ± 5%. Closer tolerances may be pro-
duced upon special order and after agreement upon mea-
surement conditions.
Typical variation of capacitance with respect to tempera-
ture is illustrated in Figure 1a. The capacitance of solid tan-
talum capacitors decreases with frequency, as shown in
Figure 1b.
Dissipation Factor — Dissipation factor is defined as the
ratio of equivalent series resistance to capacitive reactance at
a specified frequency:
Where R = equivalent series resistance in ohms
D = dissipation factor
XC = capacitive reactance in ohms
C = series capacitance in farads
f = frequency in Hertz
Unless otherwise stated, a standard frequency of 120 Hz is
used for both dissipation and capacitance measurements.
Typical behavior of dissipation factor with frequency is
shown in Figure 2. Dissipation factor loses its importance as
a measurement parameter at higher frequencies, where
impedance and ESR are the normal parameters of concern.
DC Leakage Current — The DC Leakage current limits of
Table 1 for T240 Series capacitors are the lowest generally
specified in the solid tantalum industry. Even lower leakage
currents are available on special order. Low leakage current,
aside from its intrinsic value, is an indication of anode qual-
ity. DC leakage current as a function of temperature is rep-
resented by the typical curve in Figure 3, while similar infor-
mation pertaining to leakage behavior with respect to volt-
age is contained in Figure 4.

Voltage and Temperature Ratings; Reliability Effect —
T240 Series capacitors are manufactured in 6 through 60
volt ratings at 85°C. Operation at 125°C with 2/3 rated volt-
age applied gives equivalent results, and voltage may be der-
ated linearly between these two points. Unlike wet elec-
trolytic capacitors, solid tantalum capacitors may be oper-
ated continuously at any voltage from zero to the maximum
rating without adverse effects. Operation at voltage below
nameplate improves reliability, while subsequent operation
at a higher voltage will not be affected by prior low voltage
use.
Expected reliability factors for voltages and temperatures
other than the rated conditions may be found in Figure 5.
Since T240 Series capacitors are supplied with a predeter-
mined failure rate under rated conditions, reliability under
use conditions may be estimated with this nomograph.
Circuit Impedance — Failure rates are affected by temper-
ature and voltage as described in Figure 5 and also by the
circuit impedance seen by the capacitor. Traditionally, appli-
cation advice for solid tantalum capacitors suggested an
impedance of 3 ohms or higher per applied volt. This advice
was later found to be unnecessarily conservative, and the
factors in Table II, are based on 0.1 ohm per volt as the unity
failure rate multiplier.

Equivalent Series Resistance — The equivalent series
resistance (ESR) of a solid tantalum capacitor is frequency
dependent. The curves of Figure 6 are typical of the capaci-
tor values noted, with measurements being made by con-
tacting lead wires 1/4inch from the ends of the capacitor
cases. Since ESR decreases with frequency, AC performance
at higher frequencies is considerably better than would be
predicted from the 120 Hz ratings.
Capacitor Impedance — The relationship between imped-
ance and frequency at various voltage ratings is illustrated
with typical curves in Figure 6. Impedance declines with
decreasing capacitive reactance, but ESR becomes dominant
before the self-resonant point is reached, producing the typ-
ical damped curves. Finally, impedance increases as induc-
tance of the lead wire and other capacitor elements domi-
nates. Obviously, high frequency impedance is directly
influenced by the length of lead wire and general mounting
configuration. The typical curves of Figure 6 include 1/4inch
of lead wire at each end of the capacitor.

AC Ripple — Permissable AC ripple voltage is related to
the rated voltage, the ESR of the capacitor, and the power
dissipation capability of a particular case size:
1. The positive peak AC voltage plus the DC bias
voltage (if any), must not exceed the rated voltage.
2. The negative peak AC voltage, in combination
with the bias voltage (if any), must not exceed that
allowable (see Reverse Voltage).
3. The power dissipated in the equivalent series
resistance of the capacitor must not exceed the
limits specified in Table III.
The power dissipated may be calculated from the
following:
Where E = ripple voltage across capacitor in rms volts
Z = capacitor impedance in ohms at the specified
frequency.
R = equivalent series resistance in ohms
Ripple voltage, as limited by power dissipation, may be
determined as follows:
Where P max=maximum permissible power from
Table III
Z = Impedance
R = ESR
E max (85°C) = 0.9 E max (25°C)
E max (125°C) = 0.4 E max (25°C)

Reverse Voltage — The solid tantalum capacitor is a polar
device and can be damaged by serious reversals of polarity
even for short periods of time. However , some short duration
reversal is permissable as shown in Table IV.

Surge Curr ent — Surge current testing is performed to pro-
vide resistance from damage due to circuit transients. This
test, employing total DC circuit resistance of 1.0 max, exclu-
sive of the capacitor, is described on Page 21.
Shelf Life — Shelf life is particularly difficult to define for
the solid tantalum capacitor. Extended periods of storage at
high temperature will cause some small change in leakage
current which usually returns to normal upon short time
application of working voltage. Storage at low temperatures
causes little or no degradation of leakage current. Long-term
studies of capacitance and dissipation factor shift for as long
as 45,000 hours indicate only minor variations (usually less
than 2%) in these parameters.
Installation — Mounting procedures should not place
undue strain on terminals, particularly the positive end with
its glass-metal seal. Attention to soldering technique should
avoid excessive heat transfer which might remelt the capac-
itor’s internal solder and cause loss of hermeticity or short
circuits. Potting materials should not produce excessive cur-
ing exotherms or shrinkage pressures.
