6. Fixing adhesives and coating materials.
• Do not use halogenated fixatives and coatings.
• Before using a fixative or coating, remove flux
• Dry the cleaning solution before using the adhesive
• Do not cover up all the sealing sections (terminal
• Heat curing conditions of fixative and coating.
1. Do not directly touch the terminals of solid con-
ductive polymer aluminum electrolytic capacitors.
Failure to do so can cause electric shock or burns.
Before use, allow capacitors to discharge through a
1kΩ resistor (with a sufficient margin to the heat
generation capacity) as needed.
2. Do not short-circuit between the terminals of
the solid conductive polymer aluminum electrolytic
capacitors with electric conductor. Do not subject
capacitors to conductive solutions such as acid
and alkaline water solutions.
3. Periodic inspection should be performed on the
capacitors for the industrial equipment application.
Check the following checkpoints.
• Visual inspection to check for significant defects.
• Electrical performance: leakage current, rated
4. Be careful of the following cases of emergency.
• In case of a short during use of capacitors in sets,
• In case of a short, producing gas, it may take a few

capacitors for use in electronic equipment
moistureproof bags to ensure satisfactory soldering.
Once the bag is opened right before mounting, it is
better to use up the capacitors. If some are unavoid-
ably left over, return them to the moistureproof bag,
and seal the opening hermetically.
capacitors may have increased leakage current
when unused or stored for a long time after mounted
on equipment. This phenomenon often occurs at
high ambient temperatures; however, leakage
current will decrease through voltage treatment. If
leakage current still increases after a lapse of more
than one year at ambient temperature (shorter time
at high temperatures), treat with voltage as needed.
In design of equipment, consider the effect of
increase in initial current, and install protective
circuits as needed.
