一. Caution DuringCircuitDesign

1. Please make sure the application and mounting

Conditiorts to which the capacitor will be exposed

are within the conditions specified in the catalog

or alternate product specification (Referred as to

2. Design Aluminum Electrolytic Capacitors, please

pay attentiontothe points listed below.

(1). The capacitor shall not be used in en ambient

temperature which exceeds the operating

temperature pacified in the specification.

(2). Do not apply excessive current which exceeds

the allowableripple current .

(3). Make sure that no excess voltage (that is

higher than the rated voltage)is applied to the

capacitor.

(a). Please pay attention so that the peak

voltage, which is DC voltage overlapped

by ripple current,will not exceed the rated

voltage.

(b). In the case where more than 2 aluminum

electrolytic capacitors are used in series

please make sure that applied voltage will

be lowor than rated Volrage and the voltage

be will applied to each capacitor equally

using a balancing resistor in parallel with

the capadtors.

(4). Aluminum electroiytic capacitors are poiartzed.

Make surethatno reversevoltage or AC voltage

is applied to the capacitors. Please use Bi-polar

capacitors for a circuit that can possibly see

reversed polarity. Even Bi-polar capedtorcan

not be USed for ac voltage application.

3. Appropriate capacitors which comply with the life

requirement of the products should be selected

when designing the circuit.

4. For a drcuit that repeats rapid charging discharging

of electricity, an appropriate capacitor that is

capable ofenduringsuch a condition must be used.

5. Aluminum case, cathode lead wire, anode lead

wire and circuit pattern must be isolatad.

6. The sleeve of cepacitoreisnot recognized as an

insulator, and therefore, the standard capacitor

should not be uesd in a place where insulation

function is needed.Please consult with us should

you require a higher grade of insulating sleeve.

7. Capadtors may fail if they are used under the

following conditions.

(1). Damp conditions such as water, saltwater spray,

or oil spray or fumes. High humidity or humidity

condensebon sttuations.

(2). In an atmosphere filled with toxic gasses (such

as hydrogen sulfide, sulfurous acid, nitrous acid,

chlorine. ammonia, etc. )

(3). Being exposed to direct sunlight, ozone, ultraviolet

ray, or radiation.

(4). Being exposed to acidic or alkaline solutions

(5). Under severe conditions where vibration and/or

mechanical shock exceed the applicable ranges

of the specification.

8. In designing a circuit, the following matters should

be ensured in advancetothe capacitor assemblyon

the P.C. board.

(1). Design the appropriate hole spacing to match

the lead pitch ofcapacitors

(2). Do not locate any wiring and clrcuit patterns

dirsctly above the capacitor vent, Ensure enough

free space above the capacitor vent.

(3). Do not design a circuit board so that heat

generating components are placed near an

aluminum electrolvtic capacitor Or reverse side

ofP.C. board (under the capacitor).

9. Electrical characteristics may vary depending on

changes in temperature and frequency. Please

consider this variation when you design drcuits.

10.When you mount capacitorson the double-sided

P.C boards, do not place capecttors on circuit

patterns oroveron unused holes.

11. When you install more than 2 capacitors in parallel,

considerthe balance of current flowing through the

capacitors.

12. If more than 2 aluminum electrolytic capacitors are

used in seriesmake sure the applied voltage will

be lower than the rated voltage and that voltage

will be applied to each capacitor equally using

balancing resistor in parallel witt each capacitor.
