6 FAQs about [Identification of capacitor withstand voltage]
Should a capacitor be rated 50 volts?
So if a capacitor is going to be exposed to 25 volts, to be on the safe side, it's best to use a 50 volt-rated capacitor. Also, note that the voltage rating of a capacitor is also referred to at times as the working voltage or maximum working voltage (of the capacitor).
How to choose a capacitor?
Remember that capacitors are storage devices. The main thing you need to know about capacitors is that they store X charge at X voltage; meaning, they hold a certain size charge (1µF, 100µF, 1000µF, etc.) at a certain voltage (10V, 25V, 50V, etc.). So when choosing a capacitor you just need to know what size charge you want and at which voltage.
How do you know if a capacitor has a tolerance?
The tolerance value is also printed on the capacitor. Electrolytic capacitors have a large tolerance (approx. 10 to 20%). This means that an electrolytic capacitor with a nominal capacitance of 100uF is expected to have a measured value of anywhere between 80uF and 120uF. Voltage rating The third parameter of a capacitor is its voltage rating.
What is a capacitor voltage rating?
The voltage rating is the maximum voltage that a capacitor is meant to be exposed to and can store. Some say a good engineering practice is to choose a capacitor that has double the voltage rating than the power supply voltage you will use to charge it.
How do I know if a capacitor has a voltage rating?
There are different types of representations for the voltage rating of these capacitors. Sometimes it is written clearly on the enclosure of the capacitor with its unit. For some disk capacitors, it is represented by a single underline after the capacitance value. This underline shows 100 V as the maximum working voltage.
What happens if a capacitor exceeds rated voltage?
Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.
