AlCap Useful Life Calculation Tool - Web-based Application

The AlCap Useful Life Calculation Tool provides calculations of useful life for a selected capacitor type under assumed operating conditions.

Please click on the series below in order to start the program. Next please specify the capacitor type and select the calculation method you want to use: Ripple current spectrum or Measured temperatures. In the following step enter the application-specific load conditions and start your individual calculation.

The database includes a selection of screw-terminal, snap-in, 4-/5-pin and large-size capacitors from the 2019 data book.

For customized types and for those with a preliminary part number please enter the 8-digit Customer-Specific Capacitor code in the CSC code field below. This will lead to the calculation tool, where application-specific load conditions can be entered. 

Please note that you will need a current version of Adobe Flash player to run the Useful Life Calculation Tool.
