This electronic component has been designed and developed for usage in general electronic equipment only. This product is not authorized for use in equipment where a higher safety standard and reliability standard is especially required or where a failure of the product is reasonably expected to cause severe personal injury or death, unless the parties have executed an agreement specifically governing such use. Moreover Würth Elektronik eiSos GmbH
& Co KG products are neither designed nor intended for use in areas such as military, aerospace, aviation, nuclear control, submarine, transportation (automotive control, train control, ship control), transportation signal, disaster prevention, medical, public information network etc..

Cautions and Warnings:
The following conditions apply to all goods within the product series of WCAP-PSLP of
Würth Elektronik eiSos GmbH & Co. KG:
1.1 Polarity
An Aluminum Polymer Capacitor has a polarity. In operation this polarity needs to be considered and adhered.
Reverse voltage can damage or destroy an Aluminum Polymer Capacitor. This can finally lead to a malfunction.
If the polarity in a circuit will be switched or possibly can be reversed, the usage of a non-polar capacitor shall be applied.
The polarity of an Aluminum Polymer Capacitor is for SMT V-Chip types marked like following.
On the top of the component the negative terminal is marked with a colored semicircle or bar.
Please see electrical specification within this datasheet for maximum allowed ripple current.
1.5 Charge and Discharge
Frequent and quick charge / discharge cycles may generate heat inside the capacitor. In worst case this can cause a decrease of
capacitance, an increase of leakage current or breakdown.
Applications with rapid charge and discharge cycles should be avoided. For assistance with your application please consult our technical
support.
1.6 Storage Conditions
The storage conditions for a capacitor are recommended to be 5 °C up to 35 °C and less than 75 % rel. humidity.
Do not expose the capacitor to environments with hazardous gas, ozone, ultraviolet rays or any kind of radiation. Avoid any contact of the
capacitor with direct sunshine, saltwater, spray of water or types of oil during storage..
If a capacitor is stored for a long time without applying voltage or storage conditions of 35 °C or above and more than 75 % relative
humidity, the leakage current may increase.
The leakage current will return to normal level when applying the rated voltage to the capacitor before use. If the capacitor was stored for
more than 6 months, it is recommended to apply DC working voltage to the capacitor for 30 minutes through a 1 kΩ protective series
resistor.
All products shall be used before the end of the period of 12 months based on the product date code, if not a 100 % solderability cannot be
guaranteed. The capacitance tolerance as specified within the datasheet is only valid on the date of delivery.
1.2 Overvoltage
Avoid any overvoltage and do not apply a continuous overvoltage. If an overvoltage is applied to the capacitor, the leakage current can
increase drastically. The applied working voltage is not allowed to exceed the rated working voltage of the specific capacitor.
1.3 Operating Temperature
The capacitor shall not be operated above the operating temperature, which is stated within this datasheet of the specific capacitor. The
achievable lifetime of the capacitor is correlating to the applied temperature. In order to achieve the maximum lifetime, the capacitor should
be operated by the lowest possible temperature conditions within the application.
1.7 Reflow Soldering
The detailed soldering instruction is given at H Soldering Specification in this datasheet.
1.4 Ripple Current
The applied ripple current shall not exceed the specified maximum ripple current of the capacitor.
If a higher ripple current is applied as permitted, it can cause excessive heat generation and higher temperature inside the capacitor. This
happens due to pole change effects, if ripple current is applied to the capacitor. This can result in damage or lifetime shortage of the
capacitor and may cause deterioration.
Electrolytic capacitors are regularly not designed for usage in AC applications and ripple current is applied / based due to parasitic effects on
DC signal.
1.8 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.
1.9 Cleaning
Do not wash the assembled capacitors with the following cleaning agents:
• 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
xylene: may cause deterioration of the rubber seal material
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 10 minutes.
• 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.
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.
•
•
•
•
Applying any excessive force to the lead wire or terminal.
Move or turn the capacitor after soldering to the PCB.
Bending pins after soldering.
Carrying the PCB by picking / holding the board via a capacitor.
1.12 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:
•
•
•
•
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).
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).
1.10 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:
• 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.
• 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 80% 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).
1.13 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:
• Visual inspection of the capacitor to see, if the vent operated for pressure relief and if any leakage of electrolyte has taken place.
• Measurement of electrical characteristics of the capacitor (according to datasheet, especially leakage current, capacitance and
dissipation factor).
In case of deviation or failure according to the specified characteristics, take care to start appropriate actions (e.g. replacement of capacitor).
1.14 Emergency Case
In case of excessive pressure within the capacitor the vent may operate and release this pressure. In case of vent operation gas becomes
visible, when the component is in operation. If so, directly turn off the application and disconnect it from the power source. If the application
will not be turned off, a possible short circuit of capacitor or a short circuit due to bridging of liquefied gas can possibly damage the circuit
and in worst case the application may be dramatically damaged.
Do not stay or position body or face above or in direction of the vent, because in the event of any vent operation, the releasing gas
temperature may have over 100 °C.
1.11 Mechanical Stress on lead wire and terminal
Do not stress the capacitor with the following actions:
