What is a hybrid battery & supercapacitor?
These hybrid components are not just a simple packaging of a distinct battery and supercapacitor pair in a common housing. Instead, they are energy sources that merge the chemistry of a battery with the physics of a supercapacitor in a single structure.
What is capacitor coupling?
Capacitive coupling, also called electric field coupling, occurs when the energy is coupled from one circuit to another over an electric field. When two electrical lines with different potentials are close by, then a virtual capacitor is formed between the two which causes the signal on one to couple with another.
What are X and Y capacitors?
X capacitors are available in classes X1 to X3 and Y capacitors are available in classes Y1 to Y4. Among these most commonly available classes are X1, X2, Y1, and Y2. These capacitors are impulse tested (peak pulse voltage that can withstand) to 4kV, 2.5kV, 8kV, and 5kV respectively.
Why should a small-value ceramic capacitor be used in parallel?
Some critical circuits may benefit from using a small-value (68- to 100-pF) ceramic capacitor in parallel with a larger (0.1-μF) bypass ceramic capacitor. This is because the impedance of the small-value capacitor may be much less at higher frequencies due to its much lower series inductance.

The 16 volt rating on the capacitor is the maximum safe voltage you can apply to it. You do not need to charge them to that voltage. If you do charge the capacitor to 16 volts, then connect it to a 12 volt battery, the capacitor will discharge into the battery, charging it slightly, and losing voltage in the process.
