BIPOLAR ELECTROLYTIC CAPACITORS
A distinction is made in bipolar electrolytic capacitors between two construction types,
"rough" and "smooth". "Rough" and "smooth" refer to the aluminium foil used for the
winding of the capacitor. In the rough type the foil is roughened to increase the surface
area of the foil. As the capacitance of a capacitor is proportional to the surface area,
larger capacitances can be achieved in this way with the same material costs. This
material saving is at the expense of slightly poorer electrical values. The construction
size of rough electrolytic capacitors is significantly smaller. Thus, capacitances of up to
800 µF are available in the BR63 Series.
Bipolar electrolytic capacitors are used where large capacitances are required cheaply
(series resonant circuits, impedance linearisation, etc.) or where foil capacitors (M-
CAP, MKT) are rejected for cost reasons. The higher dielectric strength of the rough
type also permits their use where smooth electrolytic capacitors are not surge-proof
enough and more expensive foil capacitors are out of the question.
