Cp is the input capacitance plus stray capacitance. You can use a few pF (3-5pF) for the value unless something is really strange. So, for a crystal rated with a 10pF load, Cl = (10pF-Cp)$cdot$2, so if we use 4pF for Cp, we get 12pF for

It appears the SRF of this capacitor would be around 100MHz (as the f where Z == ESR is 100MHz). If I go even lower in value such as 3.3nF, the SRF shifts higher, but I will gain a higher ESR and Z at the frequency I''m
How do I decide what capacitor to use in a circuit?
The values given are the minimum value needed for stability plus a little margin (usually). The regulator is a closed-loop system. It watches what happens on the output and adjusts "stuff" internally to make sure the output (really a scaled-down version of the output) always equals a desired value. Problems occur when it starts chasing its tail.

How to choose voltage value of capacitors
Yes. For electrolytics, don''t choose a voltage too far above the maximum expected working voltage. As the electrolytic''s working voltage rises, so does the ESR, assuming that the capacitance is the same. So, for a 5V application, a 1uF/700V capacitor performs much worse than a 1uF/16V capacitor. Besides, that 1uF/700V capacitor will cost quite

How to choose a capacitor?
A capacitor with an appropriate ripple current and working voltage rating should be chosen. Polarity and Reverse Voltage – If an electrolyte capacitor is used in the circuit, it must be connected in the correct direction. Its reverse voltage rating should be at least twice the possible reverse voltage in that branch of the circuit.

What should a capacitor's voltage rating be?
Apart from nominal capacitance, the voltage rating is the second most important parameter that must be essentially factored in. The capacitor’s voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors.
Why are capacitor values important?
Capacitors are vital components in electronic circuits, and understanding their values is key to making the right choice for your projects. Capacitor values determine how much energy they can store and release, directly affecting performance.
