These are typically Surface Mount Devices (SMD), often in 0603 or 1206 packages, allowing for compact PCB designs. These are typically Surface Mount Devices (SMD), often
AC mains (85-265V) enters through fuse F1 and the common mode choke L1. This choke filters electromagnetic interference (EMI). The DB1 bridge rectifier converts AC to pulsating DC, which is smoothed by C2 (100µF/400V). At 120V AC, you should measure ~170V DC across C2. At 240V AC, ~340V DC.
