(4) Monitor the cotamination levels of the cleaning solvents during use in terms of electrical conductivity, pH, specific gravity,
or water content. Chlorine levels can rise with contamination and adversely affect the performance of the capacitor.
Please consult us if you are not certain about acceptable cleaning solvents or cleaning methods.
2.7 Mounting Adhesives and Coating Agents
When using mounting adhesives or coating agents to control humidity, avoid using materials containing halogenated solvents.
Also, avoid the use of chloroprene based polymers.
　 Harden on dry adhesive or coating agents well lest the solvent should be left.
After applying adhesives or coatings, dry thoroughly to prevent residual solvents from being trapped between the capacitor
and the circuit board.
2.8 Fumigation
　In exporting electronic appliances with aluminum electrolytic capacitors, in some cases fumigation treatment
using such halogen compound as methyl bromide is conducted for wooden boxes.
If such boxes are not dried well, the halogen left in the box is dispersed while transported and enters in the
capacitors inside.
This possibly causes electrical corrosion of the capacitors. Therefore, after performing fumigation and drying
make sure that no halogen is left.
Don’t perform fumigation treatment to the whole electronic appliances packed in a box.
3. Precautions for using capacitors
3.1 Environmental Conditions
Capacitors should not be stored or used in the following environments.
(1) Exposure to temperatures above the upper category or below the lower category temperature of the capacitor.
(2) Direct contact with water, salt water, or oil.
(3) High humidity conditions where water could condense on the capacitor.
(4) Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, chlorine compound, bromine, bromine
compound or ammonia.
(5) Exposure to ozone, radiation, or ultraviolet rays.
(6) Vibration and shock conditions exceeding specified requirements.
3.2 Electrical Precautions
(1) Avoid touching the terminals of a capacitor as a possible electric shock could result. The exposed aluminum case is
not insulated and could also cause electric shock if touched.
(2) Avoid short circuiting the area between the capacitor terminals with conductive materials including liquids such as acids
or alkaline solutions.
4. Emergency Procedures
(1) If the pressure relief of the capacitor operates, immediately turn off the equipment and disconnect from the power
source. This will minimize additional damage caused by the vaporizing electrolyte.
(2) Avoid contact with the escaping electrolyte gas, which can exceed 100 ﾟ C temperatures.
If electrolyte or gas enters the eye, immediately flush the eye with large amounts of water.
If electrolyte or gas is ingested by mouth, gargle with water.
If electrolyte contacts the skin, wash with soap and water.
5. Long Term Storage
Leakage current of a capacitor increases with long storage times. The aluminum oxide film deteriorates as a function of
temperature and time. If used without reconditioning, an abnormally high current will be required to restore the oxide film.
This current surge could cause the circuit or the capacitor to fail.
After one year, a capacitor should be reconditioned by applying the rated voltage in series with a 1000Ω, current limiting resistor
for a time period of 30 minutes.
5.1 Environmental Conditions
(1) Exposure to temperatures above the upper category or below the lower category temperature of the capacitor.
(2) Direct contact with water, salt water, or oil.
(3) High humidity conditions where water could condense on the capacitor.
(4) Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, chlorine compound, bromine, bromine
compound or ammonia.
(5) Exposure to ozone, radiation, or ultraviolet rays.
(6) Vibration and shock conditions exceeding specified requirements.
6. Capacitor Disposal
When disposing of capacitors, use one of the following methods.
(1) Incinerate after crushing the capacitor or puncturing the can wall (to prevent explosion due to internal pressure rise).
(2) Dispose of as solid waste.
NOTE: Local laws may have specific disposal requirements which must be followed.
