GENERAL INFORMATION FOR APPLICATION

The following precautions must be observed when using electrolytic capacitors.

1. Circuit Design

1) Please make sure that the environmental and mounting conditions to which the capacitor to be

exposed are within the conditions specified in this catalogue.

2) Operating temperature and applied ripple must be within the specifications.

3) Appropriate capacitors, which comply with the life requirement of the products, should be selected

when designing the circuit.

4) Aluminum electrolytic capacitors are polarized. Do not apply reserve voltage or AC voltage. Please

use non-polarized capacitors for a circuit that can possibly see reserved polarity.

Note: Non-polarizes capacitors cannot be used for AC voltage application.

5) Do not use aluminum electrolytic capacitors in a circuit that requires rapid and very frequent charge

or discharge. In this type of circuit, it is necessary to use special design capacitors with extended life

characteristics.

6) Do not apply excess voltage.

Pleased pay attention so that the peak voltage, which is DC voltage overlapped by ripple current,

should not exceed the rated voltage.

In the case where more than two aluminum electrolytic capacitors are used in series, please

make sure that applied voltage should be lower than rated voltage should be applied to each

capacitor equally using a balancing resistor in parallel with the capacitor.

7) Outer sleeved of the capacitor is not guarantee as an electrical insulator. Do not use standard sleeve

on a capacitor in applications that require electrical insulation. When the application requires special

insulation, please contact our sales office for details.

8) Capacitors must not be used under following conditions:

(a) Capacitors must not be exposed to water (including condensation), brine or oil.

(b) Ambient conditions that include toxic gases such as hydrogen sulfide, sulfurous acid, nitrous

acid, chlorine, ammonium, etc.

(c) Ambient conditions that expose the capacitor to ozone, ultraviolet ray and radiation.

Severe vibration and physical shock conditions that exceed our specification.

Vibration test condition:

Vibration frequency range: 10~55~10Hz

Sweet rate

: 10~55~10Hz per minute

Sweet method

: logarithmic

Amplitude or acceleration: 1.5 (max. acceleration is 10G)

Direction of vibration

Testing time

: 2 hours per each direction

Shock is not applicable normally.

If a particular condition is required, please contact our sales office.

: X, Y, Z direction
