Matters to Be Observed When Using This Product
Matters to Be Observed When Using This Product
(Conductive Polymer Aluminum Electrolytic Capacitors / SP-Cap)
Use environments and cleaning conditions
■ This product (capacitor) is intended for standard general-purpose use in electronic equipment, and is not designed for
use in the specific environments described below. Using the product in such specific environments or service conditions,
therefore, may affect the performance of the product.
Please check with us about the performance and reliability of the product first before using the product.
(1) Used in liquid, such as water, oil, chemicals, and organic solvents.
(2) Used in a place exposed to direct sunlight, an outdoor place with no shielding, or a dusty place.
(3) Used in a wet place (dew concentration on a resistor, water leakage, etc.), a place exposed to sea breeze, or a place
filled with a corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX.
(4) Used in an environment where static electricity and electromagnetic waves are strong.
(5) The product is located close to a heating component or a flammable material, such as a vinyl cable, is placed near
the product.
(6) The product is used sealed with a resin, etc.
(7) Solder flux of the soldered product is cleansed with a solvent, water, and a water-soluble cleaner.
(Be careful with water soluble solder flux.)
(8) Used in an environment where an acidic or alkali atmosphere is present.
(9) Used in an environment where excessive vibration or impact is applied to the product.
(10) Used under a low atmospheric pressure condition or depressurized condition.
■ After soldering, clean the circuit board at a temperature of 60°C or lower for 5 minutes or less. However, ensure
to thoroughly rinse and dry it (at 100°C for 20 minutes or less). The applicable solvents are as follows.
Pine Alpha ST-100S, Clean-thru 750H/750L/710M, Aqua Cleaner 210SEP, Sunelec B-12, DK be-clear CW-5790,
Techno Cleaner 219, Cold Cleaner P3-375, Terpene Cleaner EC-7R, Techno Care FRW-17/FRW-1/FRV-1,
AXREL 32, IPA (isopropyl alcohol)
(1) Please contact us in advance for the use of cleaning agents other than those listed above and water except
pure water.
(2) Avoid using ozone-depleting substances as cleaning agents to protect the global environment.
(3) Performing ultrasonic cleaning may cause terminal disconnection, which requires prior evaluation.
■ Do not apply strong force to this product. Doing so may adversely affect mounting by causing the deformation
of electrode terminals or other defects.
In addition, the application of strong force may also lead to short circuits, disconnection, increased leakage currents,
and damage to the outer packaging of the product. Do not hold the body of the product or apply force even after it is
attached to the circuit board.
■ When the capacitor is used in a circuit where an impact voltage is applied or a high voltage is applied in a short period
(transient phenomenon) or a high pulse voltage is applied, make sure to use the capacitor at a voltage equal to or
lower than its rated voltage.
Response to anomalies and handling conditions
If this product heats up abnormally, then smoke may be generated from the exterior resin. In this case, immediately turn
off the main power of the equipment and stop using it. Also, keep your face and hands away from the product as it may
become hot and cause burns.
Reliability and product life
■ Most of the failure modes are "short circuits" or "increased leakage currents." The main causes of failures are thermal
stress, electrical stress, and mechanical stress due to reflow and operating temperature environments.
Even within the range of the specified use conditions, it is possible to reduce the failure rate by mitigating the operating
conditions such as the temperature and voltage. Therefore, please design equipment with a sufficient margin.
■ The estimated failure rate is 8.2 Fit or less (estimated at 105°C when the rated voltage is applied) based on data
obtained from the company's reliability test, while the estimated market failure rate is 0.13 Fit or less
(estimated at c = 0 and a confidence level of 60%).

Matters to Be Observed When Using This Product
Circuit design and circuit board design
■ Do not use this product in high-impedance voltage holding circuits, coupling circuits, time constant circuits, and those
that are significantly affected by leakage currents. Also, do not connect two or more units of this product in series.
■ Applying overvoltage that exceeds the rated voltage specified in the specifications or reverse voltage to this product
may cause an increase in leakage currents or short circuits.
Applied voltage refers to the voltage value applied to a circuit, including the effects of the peak values of ripple voltage
and transient instantaneous voltage, and does not only indicate the steady line voltage value. Design circuits so that
the peak voltage does not exceed the specified voltage.
Use this product by regulating the operating voltage to keep it lower than or equal to the rated voltage even for impulse
voltage circuits, applications involving transient phenomena where a considerably high voltage is applied in a short
time, and cases where high pulse voltages are applied.
■ Keep the operating temperature within the range stipulated in the specifications. Design your equipment in
consideration of not only the ambient temperature where the equipment is placed and its internal temperature,
but also the radiant heat from heating elements (power transistors, resistors, etc.) inside the equipment, and the
temperature of this product, including self-heating due to ripple current.
■ Regulate the ripple current within the rated range specified in the specifications when using the product.
Excessive ripple current causes increased leakage currents and short circuit failures due to self-heating.
Even if the ripple current is within the rated range, prevent the ripple voltage from applying overvoltage or reverse
voltage to the product.
■ The ESR rating is the value at the time of shipment from the factory. The ESR value may vary depending on the
customer's usage conditions.
■ Leakage currents may increase after reflow soldering, and also under no-load conditions at high temperatures,
in high temperature and high humidity environments, or with sudden temperature changes, even if the operating
environment is within the specified range. However, in most cases, SP-Cap reduces leakage currents due to its
self-recovery action when voltage is applied.
■ Insulate the circuit board surface directly under the mounting area of this product. Lay out your circuit board by
defining the dimensions of lands with reference to the mounting specifications stipulated in the requirements.
The dimensions of the actual design circuit should enable the optimum mounting depending on conditions such
as the circuit board, parts, and reflow.
Mounting and storage conditions
■ Check the rating (capacitance, rated voltage), polarity, and land dimensions of this product before mounting it on the
circuit board. When using mounting equipment, large pressure applied during mounting may lead to an increase in
leakage currents, short circuits, disconnection, or falling off from the circuit board.
■ Do not use flow and dip soldering. Reflow soldering can be used with the following methods. Please refer to the
mounting specifications for the recommended conditions for using the atmospheric heat conduction method.
Please contact us for the recommended conditions for using the VPS method.
(1) Atmospheric heat conduction method (infrared ray/hot-air system)
(2) VPS method (target series: CX, CT, SX, ST, GX, LX, LT, and HX)
■ Soldering must be performed at a temperature of 350°C or lower at the tip of the soldering iron and within an
operation time of 10 seconds, without applying excessive force to the product.
In addition, do not remove this product for reuse once it is mounted. Soldering outside the specified conditions can
cause short circuit failures, an increase in ESR, and other defects.
■ Store this product in an environment with a temperature ranging from 5°C to 30°C and a humidity of 70% or lower by
using a moisture-proof bag. The storage period before opening the moisture-proof bag is two years after manufacture,
and after opening the bag is seven days. If these conditions are exceeded, then the outer package may be damaged
due to thermal stress during mounting caused by moisture absorption by the package.
After opening the bag, use up all pieces of this product within the specified storage period.
■ This product is composed of various metals and resins, requiring disposal as industrial waste.
