Special designs

PAPR terminal style

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).

All other dimensions of the capacitor such as diameter d, case length l and overall length l1 are

identical with those of standard capacitors of this series. Please refer to the tables “Dimensions

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)

 Minimal overall length tolerance (±0.35 mm) for mounting between heat sink and bus bar

 Case with extra groove near the base for clamp mounting (recommended ring clamp
