Matters to Be Observed When Using This Product

■ This product (capacitor) is intended for standard general-purpose use in electronic equipment, and is not designed for

use in the specific environments described below. Using the product in such specific environments or service conditions,

therefore, may affect the performance of the product.

Please check with us about the performance and reliability of the product first before using the product.

(1) Used in liquid, such as water, oil, chemicals, and organic solvents.

(2) Used in a place exposed to direct sunlight, an outdoor place with no shielding, or a dusty place.

(3) Used in a wet place (dew concentration on a resistor, water leakage, etc.), a place exposed to sea breeze, or a place

filled with a corrosive gas, such as Cl2, H2S, NH3, SO2, or NOX.

(4) Used in an environment where static electricity and electromagnetic waves are strong.

(5) The product is located close to a heating component or a flammable material, such as a vinyl cable, is placed near

the product.

(6) The product is used sealed with a resin, etc.

(7) Solder flux of the soldered product is cleansed with a solvent, water, and a water-soluble cleaner.

(Be careful with water soluble solder flux.)

(8) Used in an environment where an acidic or alkali atmosphere is present.

(9) Used in an environment where excessive vibration or impact is applied to the product.

(10) Used under a low atmospheric pressure condition or depressurized condition.

■ When the capacitor is used in a circuit where an impact voltage is applied or a high voltage is applied in a short period

(transient phenomenon) or a high pulse voltage is applied, make sure to use the capacitor at a voltage equal to or

lower than its rated voltage.

■ A short mode is a major failure mode in a capacitor. A short mode is caused by thermal stress created by soldering or

a high service temperature, electric stress, mechanical stress, etc. When the capacitor has shorted, take the following

steps to ensure your safety.

(1) When you see smoke coming out of the shorted product, turn off the main power supply to stop using the capacitor.

Do not place your face or hand near to the smoldering capacitor.

(2) The time a shorted capacitor takes to generate smoke ranges from a few seconds to a few minutes, depending on

service conditions. If you incorporate a protective circuit, design the circuit to activate in the time preceding the smoke

generation.

(3) In case smoke gets into your eyes or comes into your mouth, wash the eyes with water or rinse out the mouth

immediately.

(4) When a current value after the short of the product is extremely large, the shorted capacitor may spark out, which,

in the worst scenario, may result in ignition. Ensure the safety of the circuit by, for example, giving it a redundant circuit

structure or providing it with a protective circuit.

The failure rate of the capacitor is specified based on 0.5%*/1000 h (reliability level 60%), a failure rate conforming to

JIS C 5003 (failure rate level). This indicates that the possibility of occurrence of a failure is by no means zero.

One of the failure modes is a wear out failure. This happens when the period of guaranteeing the durability and

high-temperature/high-humidity resistance of the capacitor is over, changes in the electrical characteristics of the

capacitor (product) get larger and its electrolyte gradually deteriorates into an insulating material to create an open mode.

Another failure mode is a random failure in which a short mode results mainly because of thermal, electrical,

or mechanical stress, etc.

* The failure rate of a small POSCAP of a B2 size or smaller is 1.0%.
