PAPR terminal style (M650, M657, M658)

An aluminum electrolytic capacitor is a polar component that needs strictly to be mounted under

correct polarity. 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 en-

ables 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) on page 9 and "Dimensions and weights for heat sink mounting"

(special designs) on page 13.
