What are the key features of TFM-147-02-S-D-LC?
- 94-position dual-row vertical surface mount design at 0.050 inch (1.27 mm) pitch delivers extremely high signal density, fitting 94 contacts in approximately 2.350 inches of board length
- Board lock (LC suffix) mechanically anchors the 94-position connector to the PCB before SMT reflow, preventing contact misalignment during peak reflow temperatures up to 260 degrees C
- Tiger Eye high-reliability contact technology ensures consistent mating engagement and signal integrity across the rated life of the connector
What is TFM-147-02-S-D-LC used for?
The TFM-147-02-S-D-LC is designed for very high density board-to-board interconnect in FPGA development boards, high-speed data acquisition systems, and multi-channel signal processing modules requiring 94 positions at 0.050 inch pitch. Its surface mount vertical orientation and board lock enable accurate automated SMT placement on large PCBs with fine-pitch component arrays. Defense electronics and high-reliability industrial computing platforms rely on the Tiger Eye contact system for stable low-resistance connections across wide temperature ranges.

Frequently Asked Questions
How does the TFM-147-02-S-D-LC board lock prevent misalignment during reflow of a 94-position fine-pitch connector?
The board lock pegs on the TFM-147-02-S-D-LC press into designated holes in the PCB, holding the 94-position 0.050 inch pitch connector against displacement caused by solder paste surface tension and thermal expansion during lead-free reflow at up to 260 degrees C. Without the lock, a connector body spanning approximately 2.350 inches can rotate or slide by fractions of a millimeter, misaligning contacts and causing open circuits or solder bridges across multiple pins.
Which FPGA or DSP board designs most benefit from a 94-position 0.050 inch pitch connector like the TFM-147-02-S-D-LC?
FPGA mezzanine boards and high-speed DSP daughter cards that route 80 or more differential signal pairs between boards benefit most from TFM-147-02-S-D-LC because it provides 94 positions in under 2.5 inches, accommodating full LVDS or LVCMOS banks at frequencies up to 500 MHz without requiring a second connector. This is critical in software-defined radio and radar signal processing platforms where connector count directly impacts form factor.
How does sourcing TFM-147-02-S-D-LC compare to procuring two 47-position connectors for the same interface?
Using a single TFM-147-02-S-D-LC with 94 positions at 0.050 inch pitch reduces BOM line items, simplifies PCB footprint layout by eliminating the gap and alignment requirements between two separate connectors, and lowers assembly cost per connection compared to placing and reflowing 2 separate 47-position connectors. A single 94-position connector also avoids inter-connector ground return discontinuities that can cause signal integrity issues above 100 MHz.
