An "F4901 1.1A 24V" designation typically refers to a specific resettable PTC (Positive Temperature Coefficient) fuse or a specialized power management circuit sub-module frequently used in industrial automation, 3D printers, and automotive control boards.
In a standard 24V DC power supply line, the F4901 fuse acts as the gatekeeper. Below is the standard schematic topology for integrating this 1.1A protection device.

is typically located within the or Backlight circuit.
This simplifies to: R1/R2 = 39 . Therefore, if R2 = 1kΩ, then R1 = 39kΩ. If R2 = 2.4kΩ, R1 = 93.6kΩ (use 93k or 100k trim). An "F4901 1

Acquire an exact replacement SMD polyfuse matching specs (package footprint size is typically 0805 or 1206 depending on precise revision). Micro-Soldering Steps Do you need a with manufacturer part numbers
Always consult the thermal derating curve in the manufacturer’s datasheet to ensure your hold current matches your expected environmental conditions. 5. PCB Layout Guidelines
When translating this schematic into a physical PCB design, adhere to the following rules:
In laptop motherboard topologies (e.g., Sandy Bridge/Ivy Bridge UMA/Muxless configurations), is placed immediately before the LVDS / LCD Connector . It handles the high-voltage power rail required to run the display's inverter board or internal LED backlight strip. The Schematic Architecture Path
