Transient Filtering Stage
Hardware Secrets Golden Award

As we have mentioned in other articles and reviews, the first place we look when opening a power supply for a hint about its quality, is its filtering stage. The recommended components for this stage are two ferrite coils, two ceramic capacitors (Y capacitors, usually blue), one metalized polyester capacitor (X capacitor), and one MOV (Metal-Oxide Varistor). Very low-end power supplies use fewer components, usually removing the MOV and the first coil.

This power supply has all required components plus one extra X capacitor and two extra Y capacitors. The MOV can be seen behind the fuse in Figure 8, using a rubber protection.
