Precautions and Guidelines for Aluminum Electrolytic Capacitors
1. Guidelines for Circuit Design
(5) Leakage Current
(6) Charge and Discharge
(7) Condition of Use
(8) Consideration to Circuit Design
Selecting the capacitors to suit installation and operating conditions, and
using the capacitors to meet the performance limits prescribed in this
catalogue or the product specifications.
(1) Polarity
(2) Operating Voltage
(3) Ripple Current
(4) Operating Temperature
Use the capacitors according to the specified operating temperature
range. If used the capacitor outside the maximum rated temperature will
considerably shorten the life or cause the capacitor to vent. Usage at
room ambient will ensure longer life.
The leakage current shall be within specified levels. When capacitors are
applied at a lower voltage, the actual leakage current will be reduced
proportionately.
The capacitor is not suitable for a circuit in which charge and discharge
are frequently repeated. The capacitance value may drop by forming
oxide layer on the cathode foil, or the capacitor may be damaged by
generating heat due to continuous rapid charge and discharge.
(a) The capacitors shall not be exposed to water, saltwater spray, oil or

Aluminum electrolytic capacitors are polarized. Make sure of the
polarity, if used in reverse polarity, the circuit life may be shortened or
the capacitor may be damaged. When the polarity in a circuit
sometimes can be reversed or unknown, a bi-polar capacitor shall be
used. Also, note that DC capacitors cannot be used for AC application.
Reverse voltage 1 voltage acceptable within specified temperature and
working voltage.
Do not apply DC voltage, which exceeds the rated voltage of the
capacitor and not be reverse voltage. If a voltage exceeding the
capacitor’s voltage rating is applied, the capacitor may be damaged as
leakage current increase. Using capacitors at recommended working
voltage prolongs capacitor life. The surge volgage rating is the
maximum DC over-voltage to which the capacitors may be subjected
of short periods.

operating temperature and applied ripple current shall not exceed the
allowable ripple current specified in the specification.

capacitor at the temperature. The expected life of a capacitor is
nearly equal to the lifetime at the upper category temperature.

has increased, please perform a voltage treatment before use.
Voltage treatment:
The capacitors shall be applied with DC rated voltage through a
resistor of 1KΩ in series for one hour, and then discharge through a
resistor of 1KΩ. When the capacitors have been assembled in the
board, use a volt regulator to input voltage gradually to the rated
voltage of the board.
