FIT Details

FIT Details view (SN29500-1)

( ) = Physical symbol

[ ] = Physical unit

Initially you need to select a component that is connected to a catalog and component type. If you click
on this component, this view appears to the right of the BOM editor. Some fields are grayed out so
you cannot enter values. This depends on the catalog and component type you use. In the example
above we used the catalog "SN29500" and the component type "K (General purpose relay...)". For
this type there are only the parameters "Stress Operation Time", "Operational Time" and "Waitstate Temperature" available.

  • Catalog: Component catalog. Either "SN29500-1" or "IEC62380-1".

  • Component type: The type of your component that you have chosen in the "New Component" dialog.

  • Failure mode type: Your selected failure mode if you have chosen one from the catalog. If you created your own failure mode in the "New Failure mode" dialog, this line will not be shown here, only the types from a catalog.

The values of the attributes are from the corresponding norm "SN29500-1" or "IEC62380-1". To change
the values, you need to edit the failure mode catalog.

  • Catalog: from your selection in the "New Component" dialog.

  • Component Type: from your selection in the "New Component" dialog.

  • Failure Mode Type: if there is a Failure mode type connected to your component, this type will be
    shown here. If there is no failure mode or you created your own, this field is empty.

  • Mission profile: in this section you have to select an existing mission profile.

  • Temperature Profile: you need a temperature profile for the FIT calculation. If you have more than
    one profile, choose a specific profile from the list after clicking the arrow.
