During wave soldering only the pins / terminals should have contact with hot solder bath / wave. Assure that no direct contact of capacitor
body with hot solder bath / wave or any other component will happen. Soldering must be done from the opposite PCB side where capacitor
body is placed.
•
•
Assure that no flux residue or spot is left between the rubber seal material of the capacitor and the PCB.
Do not fully cover the entire rubber seal surface with adhesive, coating or molding materials. Otherwise the covering of the full rubber
seal surface may restrain the natural diffusion of hydrogen gas. Block maximum 8±ꢀ of the sealed section of a capacitor.
If the used adhesive, coating or molding material is containing halogen ions in a large amount, the halogen ions can diffuse and creep
into the capacitor and can damage the capacitor. Both above explained circumstances can result in serious failures.
Follow the specified heating and curing instructions given by supplier of the used adhesive or coating material. Avoid excessive pressure
or heat on the capacitor by applying coating or adhesive.
Take care that hardening of adhesive, coating material was correctly done, so that no solvents do remain.
Be aware, that used solvents within adhesive and coating materials can damage the sleeve of the capacitor and can result in changes of
the appearance of the sleeve (color, shine and marking).

1.09 Hand Soldering
Take care that the tip of solder iron will only contact pins or leadframe of the capacitor to avoid any possible damage of the capacitor.
•
•
1.10 Cleaning
Do not wash the assembled capacitors with the following cleaning agents:
1.12 Mechanical Stress on lead wire and terminal
•
•
•
•
•
petroleum system solvents: may cause degeneration of the rubber seal material
alkali system solvents: may cause corrosion and dissolve of the aluminum case
halogenated solvents: may cause corrosion and failure of the capacitor
acetone: component marking may be erased
Do not stress the capacitor with the following actions:
•
•
•
•
Applying any excessive force to the lead wire or terminal.
Move or turn the capacitor after soldering to the PCB.
Bending pins after soldering.
xylene: may cause deterioration of the rubber seal material
Carrying the PCB by picking / holding the board via a capacitor.
Verify the following points when washing is are applied to capacitors:
•
•
Please monitor conductivity, ph-value, specific gravity and the water content of cleaning agents. Contamination adversely affects these
characteristics.
Be sure to not expose the capacitors under solvent rich conditions or keep capacitors inside a closed container. In addition, please dry
the solvents on the PCB and the capacitor sufficiently with an air knife (temperature should be less than the maximum rated category
temperature of the capacitor) for 1± minutes.
1.13 Operation and Usage of the Capacitor
In operation and usage take care about the following points.
Do not use the capacitor within the following environmental conditions:
•
Capacitors can be characteristically and catastrophically damaged by halogen ions, particularly by chlorine ions. The degree of the
damage mainly depends upon the characteristics of the electrolyte and rubber seal material. When halogen ions come into contact with
the inside of the capacitors, the foil may corrode, when a voltage is applied. This corrosion causes an extremely high leakage current,
which results in venting and an open circuit defect.
•
•
•
•
Environment with high mechanical stress / shocks or vibration (please see this specific datasheet for permitted limits).
Environment with high amount of damp condensation, water or types of oil.
Direct sunlight, ozone, any kind of radiation or ultraviolet rays.
Toxic gases (e.g. ammonium, chlorine and compounds, bromine and compounds, hydrogen sulfide, sulfuric acid).
All other cleaning processes and cleaning agents are not approved by Würth Elektronik eiSos. All cleaning methods need to be tested and
validated by the customer.
User should never touch the terminals of the capacitor directly.
Avoid short circuit between terminals with any kind of conductive material (e.g. metal, fluid, acid, alkaline solution).
1.11 Adhesives and Coating Materials
The usage of any adhesive or coating material, which is containing halogenated solvents, is not allowed.
Before applying adhesives or coating materials, make sure that the following points are fulfilled:
1.14 Maintenance
For industrial applications it is recommended to perform periodic inspections. Power supplies shall be turned off before inspection to
discharge the capacitor. Check the following points in case of an inspection:
•
Take care that the surface and capacitor is dry and clean before applying adhesive or coating, to avoid any contamination with flux
residues or cleaning solvents.
