Matters needing attention
Notes for using aluminum electrolytic capacitors
(1) DC aluminum electrolytic capacitor should be used according to
the correct polarity When the DC aluminum electrolytic capacitor is
connected to the circuit according to the reverse polarity, the
capacitor will short circuit, and the resulting current will cause
damage to the capacitor. If it is possible to apply a positive
voltage to the negative lead, select the nonpolar product.
(2) Use it below the rated working voltage When the applied voltage
on the capacitor is higher than the rated working voltage, the
leakage current of the capacitor will rise and its electrical
characteristics will deteriorate in a short time until damage. Note
that the peak voltage does not exceed the rated working voltage.
(3) Rapid charge and discharge use When conventional capacitors are
used for rapid charging, their service life may be reduced by
falling capacity, sharp temperature rises, etc.
(4) Storage of the capacitor When the aluminum electrolytic
capacitor is stored for a long time, the leakage current usually
increases, the higher the storage temperature, the faster the
leakage current rises, the longer the storage time, the higher the
leakage current value. Therefore, attention should be paid to the
storage environment and time. After the voltage is applied to the
capacitor, the leakage current value will drop continuously. If the
rise of the leakage current value of the aluminum electrolytic
capacitor has a bad effect on the circuit, please charge it before
use.
(5) The applied ripple current should be less than the rated value
When the applied ripple current exceeds the rated value, the
capacitor temperature will rise to be too high, the capacity will
decrease, and the impedance will increase (DF increases) will
shorten. The peak value of the applied ripple voltage shall be less
than the rated operating voltage.
(6) Use of the ambient temperature The service life of aluminum
electrolytic capacitors is affect by the ambient temperature.
According to scientific statistics, the use of ambient temperature
decreased by 20℃ its service life increased by 10 times.
(7) Lead line strength When a tensile force is applied to the
capacitor lead line, the tension will act inside the capacitor,
which may cause a short circuit, open circuit or rising leakage
current.weld the capacitor to the circuit board, do not shake the
capacitor strongly.
(8) Heat resistance during the welding process When the solid
polymer capacitor is loaded into the circuit board for immersion
welding or wave welding, the product body may degrade the polymer
layer and increase the leakage due to the long welding time and
high temperature.
(9) The installation hole distance and the installation position of
the circuit board The design of the mounting hole of the circuit
board shall be consistent with the lead pin distance in the product
specification. If the capacitor is forced into the circuit board
with unmatched hole distance, there will be stress on the lead
line, which may lead to short circuit or leakage current rise.
(10) About the cleaning after welding
① Capacitors cannot be cleaned with halogenated organic matter
series of cleaning agents. If cleaning is necessary, use a cleaning
agent that guarantees the capacitor quality. ② For the cleaning
agent that can ensure the quality of capacitors,please do not keep
it in the cleaning solution or sealed container after cleaning.
After cleaning, please dry with the circuit board in the hot air
for more than 10 minutes, and the temperature of the hot air should
not be higher than the upper limit of the capacitor.
(11) About fixative and coating (coating agent)
① Please do not use fixatives and coatings (coatings) containing
halogenated organic matter series. ② Please do not allow the
fixative and coating (coating agent) to seal the capacitor seal
part (terminal side).
