Applications
The TFC-118-02-L-D-A is designed for board-to-board signal interconnects in embedded computing modules, FPGA development boards, and industrial data acquisition systems where a 36-pin fine-pitch male header connects to a mating female strip. The 15 µin gold mating surface supports high-cycle test and prototype environments with repeated board insertion. Its compact 0.050" pitch footprint is also used in wireless communication module edge connectors and ruggedized avionics display interface cards.

Frequently Asked Questions
What contact material and plating does TFC-118-02-L-D-A use to ensure reliable mating in high-cycle applications?
The TFC-118-02-L-D-A uses phosphor bronze contacts with 15 µin (microinches) gold plating at the mating interface. Gold plating at this thickness provides low contact resistance, excellent corrosion resistance, and reliable electrical continuity over hundreds of mate/unmate cycles, making it suitable for test fixtures and development boards that are frequently connected and disconnected.
For a 36-signal parallel interface, how does TFC-118-02-L-D-A compare to a 0.100" pitch header in board space?
At 0.050" (1.27 mm) pitch, the TFC-118-02-L-D-A body is approximately 1.025" long for 36 positions in a dual-row layout, which is roughly half the board length required by a 0.100" pitch header carrying the same 36 signals. This space saving is critical in compact embedded modules and multi-board stack assemblies where reducing connector footprint directly reduces overall PCB dimensions and system cost.
Can TFC-118-02-L-D-A be soldered using standard lead-free assembly processes?
Yes. The matte tin (Sn) termination finish on the TFC-118-02-L-D-A solder tails is compatible with standard lead-free SAC305 solder paste and reflow profiles peaking at 260°C, as well as with wave soldering processes used for through-hole or mixed-technology PCBs. The tin finish avoids the gold embrittlement issues sometimes seen when gold-plated tails are soldered directly.
Which embedded or FPGA applications are best served by TFC-118-02-L-D-A over a higher-pitch alternative?
Applications requiring 36 or more digital signals between two closely stacked PCBs — such as FPGA expansion headers, SoC co-processor interfaces, and camera sensor modules — benefit from TFC-118-02-L-D-A because the 0.050" pitch shrinks the connector footprint without reducing pin count. Board-to-board stack heights can be kept below 10 mm when using matched Samtec TFC female receptacles, enabling very thin multi-board assemblies in robotics, drones, and portable test instruments.
