PRECAUTIONS

(1) During transportation and storage

• Do not transport or store where the capacitor will be exposed to

high temperature or high humidity.

• Do not expose to poisonous gases such as H2SO4, HCl, or

HNO3.

• Avoid excessive impact such as that caused by falling.

(2) During operation

• Avoid contact with electrolytes such as perspiration. Do not

touch with bare hands.

• Avoid excessive impact such as that caused by falling.

• Do not apply solder to stud terminals.

• Do not re-machine the terminals.

(3) Usage

• When the capacitor is used for high-speed pulses such as with a

laser, make sure that the impressed voltage (peak-to-peak volt-

age) is within the capacitor’s rated specifications.

• Make sure that the capacitor is not exposed to radiant heat from

chambers or transformers.
