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 H
2
SO
4
, HCl, or
HNO
3
.
• 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.
• For more information about products with other capacitance or other data, please contact us.
• All specifications are subject to change without notice.
