F4901 1.1a 24v Schematic |best| Jun 2026

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.

This component acts as a safety device to protect a 24V power rail from overcurrent. If the circuit draws significantly more than 1.1A, the fuse is designed to "blow" (break the circuit) to prevent damage to downstream components. Common Applications f4901 1.1a 24v schematic

The F4901 is often a proprietary marking (house number) used by Chinese OEM manufacturers. It is rarely the official datasheet name. Through reverse engineering and cross-referencing, we will uncover what this chip likely is and how to build or repair its circuit. At 120V AC, you should measure ~170V DC across C2
