What are the key features of TFM-147-21-LM-D?
- High-reliability Tiger Eye contact system at 0.050" (1.27 mm) pitch enabling twice the pin density of standard 0.100" connectors
- Dual-row layout with 94 total positions (47 per row) for ultra-high-density board-to-board signal interconnects
- Low-profile SMT construction with gold-plated contacts engineered for aerospace, defense, and high-reliability embedded systems
What is TFM-147-21-LM-D used for?
The TFM-147-21-LM-D is ideal for space-constrained high-density PCB designs in aerospace, defense electronics, and medical instrumentation where a 0.050" pitch dual-row connector provides 94 pins in minimal board area. Its Tiger Eye high-reliability contact design maintains consistent electrical performance over wide temperature swings and vibration environments. The SMT mounting style supports automated assembly and is compatible with standard reflow soldering processes.

Frequently Asked Questions
What pitch does TFM-147-21-LM-D use, and how does that compare to standard 0.100" connectors?
The TFM-147-21-LM-D uses a 0.050" (1.27 mm) pitch, which is half the spacing of standard 0.100" (2.54 mm) connectors. This allows 94 positions in the same board length that a standard pitch connector would need for 47 positions, enabling much higher signal density in compact PCB designs.
What is Samtec's Tiger Eye contact technology and why is it used in high-reliability applications?
Tiger Eye is Samtec's proprietary high-reliability contact design that provides superior wiping action during mating, ensuring gas-tight electrical connections with low and stable contact resistance. This makes the TFM-147-21-LM-D suitable for demanding applications such as aerospace, defense, and medical devices where connector failure is not acceptable over thousands of mating cycles.
How many positions does TFM-147-21-LM-D have, and what PCB areas does it serve?
The TFM-147-21-LM-D has 94 total positions in a dual-row (47 per row) configuration at 0.050" (1.27 mm) pitch. This ultra-high-density layout is used in FPGAs, high-speed signal backplanes, satellite modules, and defense avionics boards where every square millimeter of PCB area must carry maximum signal count.
When should a designer choose TFM-147-21-LM-D over a standard 0.100" pitch connector?
Choose TFM-147-21-LM-D when a design requires 94 or more board-to-board signals in minimal footprint at 0.050" pitch, especially in high-reliability contexts such as aerospace, defense, or medical devices where Tiger Eye contact integrity, SMT compatibility, and long service life outweigh the cost premium over standard 0.100" strip connectors.
