0.40 mm Pitch Board-to-FPC Receptacle, 50 Positions
The Hirose DF40TC-50DS-0.4V(51) is a 50-position receptacle from the DF40T series, designed for board-to-FPC interconnects where space is the constraint. This member carries solder retention features and is pick-and-place compatible, so it runs through an SMT line without secondary handling.
What the 1.5mm Stack Height and 0.40mm Pitch Mean for Board Layout
The 0.40mm pitch is the tightest dimension on the footprint — it forces a fine trace-and-space rule on the inner layers, typically 0.20mm lines and spaces to route the 50 signals out.
