What this 13-position FFC/FPC connector does in the assembly
The 1-84981-3 is a 13-position, 1.00 mm pitch FFC/FPC connector from TE Connectivity AMP. It terminates a standard 0.30 mm thick flat flex cable with a top-contact style, and the surface-mount right-angle orientation keeps the cable running parallel to the board — useful when the z-height above the PCB is limited to 3.00 mm. Rated at 1 A per contact and 125 V, this is a signal-level interconnect — fine for digital I/O, display links, or low-power sensor lines where the current per circuit stays under the 1 A ceiling.
The 13-position count matches the cable's conductor count exactly before committing the BOM line.
