What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.

In the replacement of capacitors with different values, one of the most important things to consider is the type of capacitor. There are three basic types: ceramic, electrolytic and tantalum capacitors. Each type has its own unique characteristics that must be taken into account when choosing a new value for a capacitor.
The capacitors in the circuit subject to the harshest conditions are C4 and C5, which act as AC smoothing or noise filter capacitors for the primary circuit. The typical working voltage on these capacitors is the full-wave rectified waveform shown in figure 2. X7R capacitors that are rated to DC 250V are often (wrongly) chosen for C4 and C5.
