What frequencies do capacitors filter?
$begingroup$ Because capacitors alone filter a wide range of frequencies. Graphs and effect for 1nF and 100nF are quiet close. (See answer below.) There isn''t much difference in effect between 5 ohms and 0.1 ohms impedance as filtering is concerned. $endgroup$ –

Capacitor Technologies Used in Filtering
Y-capacitors are used to filter out common-mode noise line-to-ground. Due to leakage current limitations imposed by most product safety standards (the harshest of which are found in medical device regulations), the capacitance value of Y-caps is very low. There are two different categories of X and Y-caps. X1 caps have an impulse rating of 4kV X2 caps are rated …

Ripple voltage filtering capacitor
In effect, this says that the diodes "instantly" charge up the capacitor. That''s not true. But it makes developing a formula easier. You''d also assume a straight line similar to the dark green curve (and not so similar to the light green curve.) Again, a simplification. With all that in hand then you can make some estimates. First off, you can see that the dark blue curve is …
