ALUMINUM ELECTROLYTIC CAPACITORS
WITH CONDUCTIVE POLYMER SOLID ELECTROLYTE
TECHNICAL NOTE
? Before transportation of electronic equipment to
overseas, fumigation process may be subjected to
wooden packing material with a halogen
(compound) gas such as methyl bromide. Exercise
care that this halogen gas may corrode capacitors.
Also, be careful of epidemic preventive agent as
corrosive component such as halogen may be
contained.
11. The case of solid conductive polymer aluminum
electrolytic capacitors and the cathode terminal are
not insulated.
? The case and the cathode terminal are not insulated
as being connected through inconstant resistance.
12. Double-sided PCB’s
? When using capacitors on a double-sided PCB,
exercise care that the wiring pattern does not touch
the area where the capacitors are mounted. Failure
to do so may cause a short to occur to the PCB
depending on the mounting conditions.
13. Regarding Connection of Solid Conductive
Polymer Aluminum Electrolytic Capacitors
? When connecting more than one capacitor in
parallel, consider the current balance.
14. Other Notes
? Do not use capacitors on a circuit where rapid
charge and discharge are repeated.
? Electrical characteristics of capacitors vary by
variations in temperature and frequency. Please
consider these variations when designing a circuit.
Cautions for Mounting
1. Cautions for Mounting
? Do not reuse capacitors that have been assembled
in a set and energized. Capacitors cannot be reused
except for those which have been measured on
electrical performance during periodic inspection.
? Before mounting, confirm the capacitor ratings
(rated capacitance and rated voltage).
? Capacitors may generate transient recovery voltage.
In this case, discharge through a resistor of about
1 k Ω .
? Before mounting, confirm the polarity of capacitor.
? Do not drop capacitors onto a floor nor use them.
? Do not mount deformed capacitors.
? Do not mount heating parts around capacitors and
on the back of the PCB under or back of capacitors).
2. Do not apply excessive pressure to the capaci-
tor or its terminals
? Be careful of the shock force that can be produced

by absorbers, product checkers, and centering on
automatic inserters and installers.
3. Soldering
? Do not solder capacitor body by dipping into melted
solder.
? Soldering conditions (preheating, soldering
temperature, terminal dipping time) should be within
the ranges specified in the catalog or the delivery
specification.
? Flux should not adhere to the parts other than the
terminals.
? When using a soldering iron, avoid excessive stress
to capacitor body.
? In reflow soldering, the reflow should be conducted
once. Please be sure to consult with us if reflow
must be conducted twice.
? Although leakage current may increase (from a few
μA to hundreds of μA) after soldering, it can be
reduced through self-repair by applying voltage. It is
advised to operate the set properly after treating
with the recommended voltage.
? In case of a long-term use of equipment, control the
soldering characteristics so that capacitors and PCB
do not fail to connect to avoid abnormal current
passage by a failure of soldering to mount.
4. Handling after Soldering
? Do not tilt, fall, raise or twist capacitor body.
? Do not pick up or move PCB by holding a capacitor.
? Do not bump capacitors against objects. When
stacking PCB’s, make sure that capacitors do not
touch the PCB’s or other components.
? Do not subject capacitors to excessive stress.
5. Cleaning after Soldering
? Recommended cleaning method
① cleaning solutions:
(a) CLEANTHROUGH 710M, 750H, 750L
(b) PINEALPHA ST-100S
(c) Techno Care FRW-4~17
(d) Isopropyl alcohol (2-propanol)
② Cleaning conditions:
(a) The temperature of cleaning solution shall be
less than 60°C.
(b) Use immersion or ultrasonic waves within two
minutes.
(c) After cleaning, capacitors and PCB’s shall
thoroughly be rinsed and dried with hot blast
for more than 10 minutes. The temperature of
such breeze should be less than the upper
category temperature.
(d) After cleaning, do not keep capacitors in
cleaning solution atmosphere or airtight
containers.
