Component Identification

Capacitors There are several types of capacitors, which also come in different values. The values are easy to determine as they are written in text on the side of the capacitor. Capacitors do however have different constructions and the electrolytic type which are cylindrical are polarised. This means that one side of the capacitor should be more negative than the other side. This is indicated by a band of - signs running down the side which must be kept most negative. The PCB which they go into normally has a + or - next to one hole to allow the part to be placed correctly.
