The standard colour code is used, but for the spot, grey is used Of colour for the number of zeros to give the value in ♟. However older ones use a colour-code system which has two stripes (for the two digits) and a spot Modern tantalum bead capacitors are printed with their capacitance, voltage and polarity in full. They are expensive but very small, so they are used where a large capacitance is needed in a small size. Tantalum bead capacitors are polarised and have low voltage ratings like electrolytic capacitors. 25V is a sensible minimum for most battery circuits. Parts list does not specify a voltage, choose a capacitor with a rating which is greater The voltage rating can be quite low (6V for example)Īnd it should always be checked when selecting an electrolytic capacitor. With their capacitance and voltage rating. It is easy to find the value of electrolytic capacitors because they are clearly printed Radial capacitors tend to be a little smallerĪnd they stand upright on the circuit board. To each end (220♟ in picture) and radial where both leads are at the same end There are two designs of electrolytic capacitors axial where the leads are attached They are not damaged by heat when soldering.

Polarised capacitors (large values, 1♟ +)Įlectrolytic capacitors are polarised and they must be connected the correct way round,Īt least one of their leads will be marked + or. There are many types of capacitor but they can be split into two groups, p means 10 -12 (million-millionth), so 1000pF = 1nFĬapacitor values can be very difficult to find because there are many types of capacitor.n means 10 -9 (thousand-millionth), so 1000nF = 1♟.Three prefixes (multipliers) are used, µ (micro), n (nano) and p (pico): However 1F is very large, so prefixes are used to show the smaller values.

This is a measure of a capacitor's ability to store charge.Ī large capacitance means that more charge can be stored.Ĭapacitance is measured in farads, symbol F. Signals but they block DC (constant) signals. They are also used in filter circuits because capacitors easily pass AC (changing) Smooth varying DC supplies by acting as a reservoir They are used with resistors in timing circuitsīecause it takes time for a capacitor to fill with charge.
