What are the key features of TFML-149-02-S-D-P-TR?
- 98-position dual-row Tiger Eye locking terminal strip at 0.050" (1.27 mm) pitch for very high-density board-to-board interconnects
- Tiger Eye contact system providing enhanced normal force and low contact resistance maintained across repeated mating cycles
- Polarized (P) locking mechanism preventing incorrect connector orientation and accidental unmating in vibration-prone environments
- Tape-and-reel (TR) packaging enabling automated high-volume SMT assembly with pick-and-place equipment
What is TFML-149-02-S-D-P-TR used for?
The TFML-149-02-S-D-P-TR is designed for very high-density board-to-board signal interconnects on FPGA development boards, server backplanes, and embedded computing modules requiring 98 positions at 0.050" pitch in a locking SMT format. The Tiger Eye contact technology maintains reliable electrical contact at low insertion forces while the polarized lock prevents mis-mating in industrial systems subject to shock and vibration. Tape-and-reel delivery supports automated SMT production for high-volume computing and telecom hardware.

Frequently Asked Questions
What does SAMTEC's Tiger Eye contact technology offer in the TFML-149-02-S-D-P-TR compared to standard beam contacts?
SAMTEC's Tiger Eye contact system uses a dual-beam wiping design that generates higher normal force per contact than standard single-beam designs, typically achieving contact resistance below 20 mΩ across all 98 positions. This enhanced normal force maintains reliable electrical connection through vibration and thermal cycling from -55°C to +125°C, making TFML-149-02-S-D-P-TR ideal for high-reliability embedded computing and telecom infrastructure applications.
How does the polarized (P) locking feature on the TFML-149-02-S-D-P-TR prevent assembly errors in dense multi-connector PCB designs?
The P designation adds a polarizing key that makes the TFML-149-02-S-D-P-TR connector physically asymmetric, so it can only mate in the correct orientation with the matching 98-position male strip. The locking feature adds a positive audible click retention, with extraction force typically above 200 g per connector, preventing accidental unmating on boards in vibrating industrial enclosures or portable equipment.
What board-to-board signal count and footprint does the TFML-149-02-S-D-P-TR provide for high-density FPGA module designs?
The TFML-149-02-S-D-P-TR provides 98 positions across 2 rows at 0.050" (1.27 mm) pitch, with 49 positions per row spanning approximately 62 mm of board length. This enables routing 98 signals—sufficient for a full 16-bit or 32-bit data bus with control signals—in a narrow SMT footprint, well-suited to FPGA SOM carrier boards, high-pin-count daughtercards, and dense telecom interface modules.
For a new embedded computing module design, when should an engineer use TFML-149-02-S-D-P-TR instead of an 0.100" pitch alternative?
Engineers choose TFML-149-02-S-D-P-TR over 0.100" (2.54 mm) pitch alternatives when they need to route 98 signals in half the board footprint, since the 0.050" (1.27 mm) pitch halves the connector length from approximately 124 mm to 62 mm. This space saving is decisive in compact SOM and COM Express modules where board area is constrained to under 95 mm x 95 mm and high signal count is simultaneously required.
