How do I choose the right capacitor?
When choosing the right capacitor, consider the following: Capacitance value: The capacitance value is critical as it determines the amount of electric charge the capacitor can store. Selecting the appropriate capacitance is key to ensure it meets the circuit’s functional requirements.
What type of capacitor should I use for audio frequency work?
In choosing coupling capacitors for audio frequency work, aluminum electrolytics or tantalum capacitors may be a good option. Niobium electrolytic capacitors may suit low-voltage applications (10 volts or less) with safety concerns. Higher voltage applications and operation at higher frequency may require Class 2 ceramic capacitors.
What type of capacitor should I use?
In both cases the capacitors should have low leakage current and have adequate precision. The best choices for feedback capacitors are class 1 ceramic capacitors, polystyrene film capacitors, and for high temperature applications, polycarbonate film capacitors.
How to choose a film capacitor?
Thus, the first option is to consider an electrolytic capacitor. In some applications that the ripple current is very high, electrolytic capacitor will not work anymore as its ripple current is smaller. In this case, film capacitors are chosen as they are having very high ripple current rating.
Which capacitor should be used for rectification?
For rectification, it requires most of the times a larger capacitance to get a near straight line voltage. Thus, the first option is to consider an electrolytic capacitor. In some applications that the ripple current is very high, electrolytic capacitor will not work anymore as its ripple current is smaller.
Which capacitor should be used for low-level energy storage?
Low-level energy storage in peak detector and sample-and-hold circuits should employ polystyrene capacitors because of their low dielectric absorption characteristic.
