There are different types of filters available namely LPF (low pass filter), BPF (bandpass filter), HPF (high pass filter), capacitor filter, etc. The main function of the capacitor, as well as an inductor in this circuit, is, a capacitor allows the ac and blocks the dc, whereas an inductor permits only DC components to supply and blocks ac.
How to Calculate Capacitors in Series. When capacitors are connected in series, on the other hand, the total capacitance is less than the sum of the capacitor values. In fact, it''s equal to less than any single capacitor value in the circuit. Capacitors connected in series are equivalent to a single capacitor with a larger spacing between the ...

This calculator allows you to select the order of the crossover and the filter characteristic. The simplest is a 1st-order crossover design, which uses only one capacitor and one inductor has a 6 dB/octave slope, which is the lowest slope possible.

Building my understanding of the issue from (First PSU - need help with capacitor size) (especially the comments/ripple wiki/several capacitor sizing webpages) the calculation for rectifying a full wave bridge rectifier at 50A 16V should be:$$frac{50A}{2 * 60Hz * 2V (Ripple)} = .208333$$ Converting from F to uF, I get $$.208333*10^6=208,333uF$$
filter capacitor in this role. The current pulses charging the capacitor when the diode(s) are forward-biased are generally much briefer than the time the capacitor is discharging into the load. Due to the principle of Charge Conservation in a capacitor, these pulses are therefore quite a bit higher in amplitude than the load current.

Capacitor Filter A half-wave rectifier with a capacitor-input filter is shown in Figure 2. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of a load. We will use the half-wave rectifier to illustrate the basic principle and then expand the concept to full-wave rectification.
It''s an approximate formula because it assumes the discharge of the capacitor between recharges is linear (it''s actually exponential) but is reasonable for ripples up to 10%. So for 100 amps with a ripple voltage of (say) 5Vp-p at 60Hz, the capacitance is 0.333 farads.
A bypass capacitor is an indispensable tool in electronic circuits. It is used to stabilize voltage and filter out noise. For the purpose of effective noise reduction and circuit stability a right type of bypass capacitor be chosen as it is too important for the balanced performance of electronic circuits against high frequency noise and balanced voltage levels.

atmel defines the stray capacity as being from xtal terminal to gnd. NXP defines the stray capacity as parallel to the crystal. This gives. Stray capacities: Catmel =2 Cnxp. so it is all a matter of definition. Anyway there are typically some "handwaving" involved in stray estimates anyway.
