With our PAPR terminal style (Protection Against Polarity Reversal) we offer an optional
mechanical feature in addition to the visual polarity marking on the cover disk and the sleeve,
which prevents from mounting in reverse polarity. The non-circular shape of the terminals and
their arrangement perpendicular to each other enables the user to definitely prevent wrong
mounting with respect to polarity (Poka Yoke).

and weights” (standard types) and “Dimensions and weights for heat sink mounting” (special
designs).
For heat sink mounting
Design for optimal connection of capacitors to the heat sink when using base cooling with the
following features (refer to chapter "General technical information, 5.2 Cooling"):

Electrical insulation of the capacitors base with 2 overlapping thermal pads for optimal heat
flow (minimal thermal resistance at the capacitor base)
