6 FAQs about [Capacitors have current ratings]
Do perfect capacitors have a voltage rating?
They have a voltage rating, when AC is applied to a perfect capacitor the current leads the voltage by 90° so no heating effect takes place at the rated voltage.
How are capacitor ratings determined?
Capacitor ratings are determined by how close to the actual values they are when compared to the rated nominal capacitance. Letters and colored bands are used to indicate actual tolerance. Common tolerance levels for capacitors sit around 5% - 10%. However, some capacitors made of plastic have been rated as low as ±1%.
How do you know if a capacitor is bad?
This information is vital to know because if the wrong capacitor is used (such as a capacitor with a smaller rated voltage rating being used in place of a capacitor with a higher voltage rating) than the capacitor can be damaged and even destroyed. The characteristics of a capacitor can be found in the data sheets provided by the manufacturer.
What are capacitor characteristics?
Capacitor Characteristics Capacitors are often defined by their many characteristics. These characteristics ultimately determine a capacitors specific application, temperature, capacitance range, and voltage rating. The sheer number of capacitor characteristics are bewildering.
What temperature does a capacitor work?
Generally, most capacitors work well between -30oC to +125oC. Nominal voltage ratings for a working temperature for plastic capacitor types are no more than +70oC. Electrolytic capacitors and aluminium electrolytic capacitors are susceptible to deformation at high temperatures because of leaking and internal pressure.
What is the working voltage of a capacitor?
The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).
