Which parameters should I consider to choose safety capacitor?
You can use normal capacitors to get common-mode noise reduction but, that wouldn''t be allowed on lines that are live where the failure of a capacitor can either cause a shock hazard or a fire. X and Y capacitors are designed not to cause fires and shock people in these circumstances. $endgroup$

How to pick voltage rating for capacitors
High-K ceramic capacitors (X7R and the like) lose capacitance as the electric field increases. The electric field is the inverse of the distance between electrodes. Thus, a larger thicker cap (1206 vs 0603) will have thicker dielectric, a higher voltage rating, and capacitance will drop less with voltage.
oscillator
There''s a lot of info and guides on how to select and calculate load capacitors for the parallel resonant circuits. They all assume that people do already possess crystal, and know its CL. That CL ... $begingroup$ You need to get the various formulas that describe the negative-resistance regions (where the circuit can oscillate), …
Choosing a capacitor? Ripple current capability matters as much …
If a capacitor with nominal capacitance of 22µF and voltage rating of 16V is chosen, as the nearest standard value above 19.22µF, the actual capacitance of this device is 5.951µF at 400kHz, as shown in figure 1, and the ESR is 3.328mΩ.
What Size Capacitor Do I Need for Air Conditioner?
For example, if your old 240-Volt capacitor needs replacing and you can only find one rated at 216 Volts, that should still work just fine since 216 is within 10% of 240 (240 x 0.1 = 24; 240 – 24 = 216). Second, choose a replacement with at least equal
The Basics of Capacitor Values

Do You Need a Capacitor on a Drone? Here''s What I Recommend
So what value of capacitance should we choose for our FPV drone? Personally, I would recommend the following: For 3 inch sized drones and under: use a 220uF to 470uF, as large as your build will allow. For …
Should I Use a Tantalum or Class II MLC Capacitor in My Circuit?
However, one big benefit of tantalum capacitors is that these capacitors can handle capacitance values up to 1,000 µf, which is 10X greater than the maximum capacitance value of a Class II MLCC. This makes tantalum capacitors a good fit for applications that need quick bursts of high capacitance and charge in a small package …
