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