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.
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.
Choosing the right capacitor for an application can make a significant difference in the performance, reliability, and efficiency of products such as power supplies for defense, aerospace, medical technology, critical energy infrastructure, or fast EV chargers.
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.
Though there are few cases to install a capacitor in series. In my designs, I am not allowing to a voltage stress of more than 75%. This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V.
Voltage Balancing: Ensure that the capacitors in series are of the same type and value to maintain voltage balance. Using capacitors from reputable brands like Murata, AVX Corporation, or Kemet can help ensure consistency. Leakage Current: Be mindful of the leakage current, which can vary between capacitors.
