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-AI3H of
Würth Elektronik eiSos GmbH & Co. KG:
1.1 Polarity
An Aluminum Electrolytic Capacitor has a polarity. In operation this polarity needs to be considered and adhered.
Reverse voltage can damage or destroy an Aluminum Electrolytic 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 Electrolytic Capacitor is for Snap-In types marked like following.
A minus sign on one of the claw fasteners indicates the negative terminal.
On the sleeve the negative terminal is marked with a color band and thereon are minus signs given.
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 Vent
On most Aluminum Electrolytic types, a predetermined breaking point is given on the top of the component, which is the so called vent. The
vent is there to assure a possible pressure relief and to avoid that the capacitor can explode due to internal pressure, which can occur by
applying reverse voltage or a too high ripple current.
A space of at least 3mm above the vent is recommended, in order to assure the full function of the vent. If less space is present the vent
maybe cannot operate correctly / completely.
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.
1.7 Sleeve
The sleeve material consists of PET (polyethylene terephthalate). If excessive heat is applied to the sleeve (e.g. soldering process, etc.) the
sleeve may crack or deform.
If the capacitor will be exposed to xylene, toluene or likewise and will be afterwards heated, the sleeve may crack or deform.
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.
The sleeve does not assure any electrical insulation. It is to avoid to use / place the product on a spot where electrical insulation is needed.
To assure electrical insulation, especially to the case of capacitor, further actions need to be taken.
1.8 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.

GENERAL TOLERANCE

METHOD
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.
