Physical size and form factor: The physical size and form of the capacitor should be considered to ensure it fits within the spatial constraints of your design. Temperature range: Selecting a capacitor that can operate within the environmental temperature extremes of your application is essential for reliable performance.
How to select capacitors?
Aside from the capacitance, another thing to consider on how to select capacitors is the tolerance. If your application is very critical, then consider a very small tolerance. Capacitors come with several tolerance options like 5%, 10% and 20%. It is your call which is which.
Why is it important to choose the right capacitor?
Choosing the right capacitor is important in the present electronic world, as every device requires capacitors. The type of capacitor is also crucial, as it is available in different forms and with different ratings. Everything will be discussed in detail and all the points are kept in simple words which help easy to understand.
How do you identify a capacitor?
You can identify a capacitor by examining its physical characteristics. Capacitors typically have markings that indicate their capacitance value (often in microfarads, µF), voltage rating, and sometimes the type (e.g., ceramic, electrolytic). The physical size and shape (cylindrical, disc, rectangular) can also give clues about its type.
What is a good voltage rating for a capacitor?
The capacitor physical size is directly proportional to the voltage rating in most cases. For instance, in the sample circuit above, the maximum level of the voltage across the capacitor is the peak level of the 120Vrms that is around 170V (1.41 X 120V). So, the capacitor voltage rating should be 226.67V (170/0.75).
How is an electrolyte capacitor made?
An electrolyte capacitor is made using a tantalum oxide film or a few micrometers thickness of aluminium oxide as a dielectric. This results in a capacitor with a high value due to the thin dielectric. The thickness of the dielectric is inversely proportional to the capacitance. The working voltage of the device is reduced in this process.
