- | There are two designs of electrolytic capacitors; **axial** where the leads are attached to each end (220µF in picture) | + | There are two designs of electrolytic capacitors; **axial** where the leads are attached to each end and **radial** where both leads are at the same end. Radial capacitors tend to be a little smaller and they stand upright on the circuit board while axial capacitors can have a lower profile on a PC board but may take up more space. |
