Panasonic EE26 Precautions for using capacitors, Emergency Procedures, Long Term Storage

Aluminum Electrolytic Capacitor

(3)A thorough drying after cleaning is required to remove residual cleaning solvents which may be trapped between the capacitor and the circuit board. Avoid drying temperatures which exceed the maximum rated temperature of the capacitor.

(4)Monitor the contamination levels of the cleaning solvents during use by 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 for additonal information about acceptable cleaning solvents or cleaning methods.

2.9 Mounting Adhesives and Coating Agents

When using mounting adhesives or coating agents to control humidity, avoid using materials containing h a l o g e n a t e d s o l v e n t s . A l s o , a v o i d t h e u s e o f chloroprene based polymers.

✽After applying adhesives or coatings, dry thoroughly to prevent residual solvents from being trapped between the capacitor and the circuit board.

3. Precautions for using capacitors

3.1 Environmental Conditions

Capacitors should not be used in the following environments.

(1)Temperature exposure above the maximum rated or below the minimum rated temperature of the capacitor.

(2)Direct contact with water, salt water, or oil.

(3)High humidity condition s w h e r e water could condense on the capacitor.

(4)Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, or ammonia.

(5)Exposure to ozone, radiation, or ultraviolet rays.

(6) V i b r a t i o n a n d s h o c k c o n d i t i o n s e x c e e d i n g specified requirements.

3.2 Electrical Precautions

(1)Avoid touching the terminals of the capacitor as possible electric shock could result. The exposed aluminium 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 vent 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°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 aluminium 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. Capacitor should be reconditioned by applying rated voltage in series with a 1000 Ω, current limiting resistor for a time period of 30 minutes.

5.1 Environmental Conditions (Storage)

Capacitors should not be stored in the following environments.

(1)Temperature exposure above 35°C or below 15 °C.

(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, or ammonia.

(5)Exposure to ozone, radiation, or ultraviolet rays.

(6)Vibration and shock conditions exceeding specified requirements.
