Board-fit reality for a 10-circuit vertical FFC
The 1-84982-0: This is a 10-position, 1.00 mm pitch FFC/FPC connector from TE Connectivity's 84982 series, terminated by solder to the board surface-mount pads. The contacts are vertical and single-sided — the FFC inserts straight in and mates against one row of tin-plated phosphor bronze beams.
What the 5.59 mm standoff means for your stack
The FFC thickness accepted is 0.30 mm, a common value for standard signal flex circuits. If your FFC is thicker or thinner, the contact wipe and retention change; stick with 0.30 mm nominal.
