1) Refer to chapter "General technical information, 5 Useful life" on how to interpret useful life.

Useful life1)

For useful life calculations, please use our web-based "AlCap Useful Life Calculation Tool", which

can be found on the Internet under the following link:

www.tdk-electronics.tdk.com/alcap

The AlCap Useful Life Calculation Tool provides calculations of useful life as well as additional da-

ta for selected capacitor types under operating conditions defined by the user.

In addition, it is possible to calculate useful life expectancies based on temperatures measured by

the user in the application.
