| Modern tantalum bead capacitors are printed with their capacitance, voltage and polarity in full. However older ones use a colour-code system | |

| Tantalum bead capacitors are polarised and have low voltage ratings like electrolytic capacitors. They are expensive but very small | |

| The voltage rating can be quite low (6V for example) and it should always be checked when selecting an electrolytic capacitor. | |

| If the project parts list does not specify a voltage, choose a capacitor with a rating which is greater than the project's power supply voltage. 25V is a sensible minimum for most battery circuits. | |

| It is easy to find the value of electrolytic capacitors because they are clearly printed with their capacitance and voltage rating. | |
