Have a look at our lineup of affordable miniature electrolytic capacitors including twenty-five volt radial capacitors as well as fifty volt radial and axial capacitors. Because they have roughened anodes and because of the relatively high permittivity of the oxide layers, electrolytic capacitors have notably high capacitance per unit of volume compared to film and ceramic capacitors, making them appropriate in higher-current and low-frequency electrical circuits.
