What are the parameters of capacitors?
The capacitance of a capacitor is the amount of charge it can store per unit of voltage. The unit for measuring capacitance is the farad (F), named for Faraday, and is defined as the capacity to store 1 coulomb of charge with an applied potential of 1 volt.
How do you know if a capacitor is right?
The general rule is always use a capacitor with a higher working voltage than the circuit it is used in. This is of particular importance in power supply circuits with high value electrolytic capacitors. The working voltage should always exceed the peak working voltage of the circuit by a minimum of 20%.
How to tell the voltage of a capacitor?
Either date code (usually two digits) or some lot number identification, or maybe both. This is not so well defined, as far as I know. Unfortunately I am not sure if you can find out just from these markings the manufacturer of the capacitors. But the rated capacitance and voltage information should be 33μF/100V and 100μF/16V.
Do you need a code for an electrolytic capacitor?
Electrolytic capacitor markings: Many leaded capacitors are quite large, although some are smaller. As such it is often possible to provide the complete value and details in a non-abbreviated format. However many smaller electrolytic capacitors need to have coded markings on them as there is insufficient space.
What do the markings on a capacitor mean?
The markings on this type of capacitors usually are: Either date code (usually two digits) or some lot number identification, or maybe both. This is not so well defined, as far as I know. Unfortunately I am not sure if you can find out just from these markings the manufacturer of the capacitors.
What do the markings mean on a tantalum capacitor?
SMD tantalum capacitor markings In some cases the only marking shown on the capacitor may be a bar across one end indicating the polarity. This is particularly important because it is necessary to be able to check the polarity and to have a marking to identify the polarity of the capacitor.
