SIZE

Size: 8.0 x 11.7

1.13 Maintenance

For industrial applications it is recommended to perform periodic inspections. Power supplies shall be turned off before inspection to dischar-

ge 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 dissipati-

on 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 visi-

ble, 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.

In case of contact with the electrolyte on skin, wash the skin immediately with soap and water. If the eyes will get in contact with the releasing

gas, immediately wash the eyes with water. Whether the gas was inhaled, directly use gargle.

1.14.1 Additional Requirements for Aluminum Polymer Capacitors

Circuits and Designs where the usage of Aluminum Polymer Capacitors is prohibited are:

a) High-impedance circuits

b) Coupling Circuits

c) Time Constant Circuits

Due to thermal stress the leakage of Aluminum Polymer Capacitor can vary within the above stated applications.

If you want to use two or more Aluminum Polymer Capacitors in series connection for circuit designs, which are significantly affected by leaka-

ge current, please contact our technical staff before usage.

1.15 Disposal

Please contact your local responsible or organization for proper disposal of capacitor.

Also take care to be compliant in order to your local governmental law and restrictions. In case incineration, it should be done with more than

800 °C. Lower temperatures at incineration can result in toxic gases (e.g. chlorine). To avoid any explosion of capacitor, punch holes into the

can or crush the capacitor before incineration.
