APPLICATION MANUAL
The operational attentions to the use of the tantalum capacitors are as follows:
- Electrical
- Environmental
- Conditions for mounting on equipment and circuit boards
- Mechanical vibration, shock
If the tantalum capacitors are used without satisfying any one of these conditions, the probability of
short-circuiting, leakage current, ignition or other problems to occur increases. To avoid such
problems, observe the following precautions when using the tantalum capacitors.
● OPERATING VOLTAGE
▶ The voltage derating factor should be as great as possible. Under normal conditions, the operating
voltage should be reduced to 50% or less of the rating. It is recommended that the operating
voltage be 30% or less of the rating, particularly when the tantalum capacitors are used in a lowimpedance circuit (see Figs. 1, 2, and 3).
▶ For circuits in which a switching, charging, discharging, or other momentary current flows, it is
recommended that the operating voltage be 30% or less of the rating, with a resistor connected in
series to limit the current to 300 mA or less.
▶ When the tantalum capacitors are to be used at an ambient temperature of higher than 85℃, the
recommended operating range shown in Fig. 3 should not be exceeded.

● RIPPLE
The maximum permissible ripple voltage and current are related to the ratings case size.
Please consult us detail in formations.
▶ Ripple Current
The maximum permissible ripple current, IMAX, is calculated as follows :
PMAX
IMAX =
ESR(f)
where:
IMAX
: Maximum permissible capacitor ripple current (Arms).
PMAX : Maximum permissible capacitor power loss (W).
Varies with the ambient temperature and case size.
Calculated according to Table
ESR(f): Capacitor equivalent series resistance (Ω).
Since the ESR(f) value varies with the ripple frequency, however, the following correction must be
made in accordance with the operating frequency (see Fig. 4).
ESR(f) = K · ESR(120)
K : Coefficient for the operating frequency (Fig. 4).
ESR(120) = Tan δ · Xc =
Tan δ
2πfC
where:
ESR(120) : Equivalent series resistance at 120 Hz (Ω).
Xc : Capacitive reactance at 120 Hz (Ω).
C : Electrostatic capacitance at 120 Hz (μF).
f : Operating frequency (Hz).

▶ Ripple Voltage
If an excessive ripple voltage is applied to the tantalum capacitors, their internal temperature
rises due to Joule heat, resulting in the detriment of their reliability.
▷ The tantalum capacitors must be used in such a conditions that the sum of the Working Voltage
and ripple voltage peak values does not exceed the rated voltage (Fig. 5)
▷ Ensure that an reverse voltage due to superimposed voltages is not applied to the capacitors.
▷ The maximum permissible ripple voltage varies with the rated voltage. Ensure that ripple voltage does
not exceed the values shown in Figs 6 and 7. If, however, the capacitors are used at a high
temperature, the maximum permissible ripple voltage must be calculated as follows:
Vrms(at 55℃) = 0.7 x Vrms(at 25℃)
Vrms(at 85℃) = 0.5 x Vrms(at 25℃)
Vrms(at 125℃) = 0.3 x Vrms(at 25℃)

● REVERSE VOLTAGE
Solid tantalum capacitors are polarized device and may be permanently damaged or destroyed, if
connected with the wrong polarity.
▷ The tantalum capacitors must not be operated and changed in reverse mode. And also the
capacitors must not be used in an only AC circuit.
▷ The tantalum capacitor dielectric has a rectifying characteristics. Therefore, when a reverse
voltage is applied to it, a large current flows even at a low reverse voltage.As a result,it may
spontaneously generate heat and lead to shorting.
▷ Make sure that the polarity and voltage is correct when applying a multi-meter or similar testing
instrument to the capacitors because a reverse voltage or overvoltage can be accidentally
applied.
▷ When using the capacitors in a circuit in which a reverse voltage is applied, consult your local
SAMSUNG ELECTRO-MECHANICS agent. If the application of an reverse voltage is
unavoidable, it must not exceed the following values.
At 20°C: 10% of the rated voltage of 1 V, whichever smaller.
At 85°C: 5% of the rated voltage or 0.5 V, whichever smaller.
● RELIABILITY OF TANTALUM CAPACITORS
▶ General
The failure rate of the tantalum capacitor varies with the digression ratio, ambient temperature, circuit
resistance, circuit application, etc.
Therefore, when proper selections are made so as to afford additional margins, higher reliability can
be derived from the tantalum capacitors. Some examples of actual failure rates are presented below
for your reference.
▶ Failure Rate Calculation Formula
The tantalum capacitors are designed to work at their basic failure
rates shown in Table 3 that prevail when the rated voltage is applied for 1000 hours at 85℃.

KV :
KR :
Failure rate correction coefficient by the ambient temperature and derating factor.
Failure rate correction coefficient by the circuit resistance,
which is the series-connected resistance divided by the voltage applied to the capacitor.
This resistance is connected in series when the power supply side is viewed from the capacitor side.
K(derating factor)=operating voltage/rated voltage
● RELIABILITY PREDICTION
Solid tantalum capacitors exhibit no degration failure mode during shelf storage and show a constantly
decreasing failure rate(i.e. , absence of wearout mechanism) during life tests. this failure rate is
dependent upon three important application conditions:DCvoltage, temperature, and circuit impedance.
Estimates of these respective effects are provided by the reliability nomograph.(Figure 8.)
The nomograph relates failure rate to voltage and temperature while the table relates failure rate to
impedance. These estimates apply to steady-state DC condition, and they assume usage within all
other rated conditions.
Standard conditions, which produce a unity failure rate factor, are rated voltage, +85℃, and 0.1 ohmper-volt impedance.
While voltage and temperature are straight-forward, there is sometimes difficulty in determining
impedance. What is required is the circuit impedance seen by the capacitor. If several capacitors are
connected in parallel, the impedance seen by each is lowered by the source of energy stored in the
other capacitors. Energy is similarly stored in series inductors.
Voltage "de-rating" is a common and useful approach to improved reliability. It can be persued too far,
however , when it leads to installation of higher voltage capacitors of much larger size.
It is possible to lose more via higher
inherent failure rate than is gained by
voltage derating. SAMSUNG typically
recommends 50% derating, especially in
low impedance circuits.
Failure rate is conventionally expressed in
units of percent per thousand hours. As a
sample calculation, suppose a particular
batch of capacitors has a failure rate of
0.5% / Khr under standard conditions.
What would be the predicted failure rate at
0.7times rated voltage, 60℃ and 0.6Ω/V?

● MOUNTING PRECAUTIONS
▶ Limit Pressure on Capacitor Installation with Mounter
A capacitor that has been damaged should be discarded to avoid later problems resulting from
mechanical stress.
Pressure must not exceed 4.9 N with a tool end diameter of 1.5mm when applied to the
capacitors using an absorber, centering tweezers, or the like. An excessively low absorber setting
position would result in not only the application of undue force to the capacitors but capacitor and
other component scattering,circuit board wiring breakage, and / or cracking as well, particularly
when the capacitors are mounted together with other chips having a height of 1 mm or less.
▶ Flux
▷ Select a flux that contains a minimum of chlorine and amine.
▷ After flux use, the chlorine and amine in the flux remain and must therefore be removed.

▶ Cleaning after Mounting
The following solvents are usable when cleaning the capacitors after mounting. Never use
a highly active solvent.
- Halogen organic solvent (HCFC225, etc.)
- Alcoholic solvent (IPA, ethanol, etc.)
- Petroleum solvent, alkali saponifying agent, water, etc.
Circuit board cleaning must be conducted at a temperature of not higher than 50°C and for
an immersion time of not longer than 30 minutes. When an ultrasonic cleaning method is
used, cleaning must be conducted at a frequency of 48 kHz or lower, at an vibrator output
of 0.02 W/cm3, at a temperature of not higher than 40°C, and for a time of 5 minutes or shorter.
NOTE 1: Care must be exercised in cleaning process so that the mounted capacitor will not come
into contact with any cleaned object or the like or will not get rubbed by a stiff brush or
the like. If such precautions are not taken particularly when the ultrasonic cleaning
method is employed, terminal breakage may occur.
NOTE 2: When performing ultrasonic cleaning under conditions other than stated above, conduct
adequate advance checkout.
