 Electrolytic capacitors are polarized and **they must be connected with the correct orientation**,​ at least one of their leads will be marked with a + or -. They are not generally damaged by heat when soldering but can overheat and be damaged if connected with the wrong polarity. Electrolytic capacitors are polarized and **they must be connected with the correct orientation**,​ at least one of their leads will be marked with a + or -.

-There are two designs of electrolytic capacitors; **axial** where the leads are attached to each end (220µF in picture) ​and **radial** where both leads are at the same end (10µF in picture). Radial capacitors tend to be a little smaller and they stand upright on the circuit board.+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.
