Key Features
- Tiger Eye contact technology delivers reliable 0.050" (1.27 mm) pitch mating with positive latching and low contact resistance for high-density signal routing
- Dual-row 94-contact layout provides maximum pin density in a minimal PCB footprint for compact module interconnects
- Polarization feature (-P) prevents misalignment during mating, eliminating incorrect orientation in automated and manual assembly
- Tape and reel (-TR) packaging enables continuous SMT pick-and-place assembly at high throughput for volume production
Applications
The TFM-147-12-LM-D-A-P-TR is suited for high-density board-to-board and module-to-mainboard interconnection in networking equipment, FPGA development platforms, and data acquisition systems. Its 0.050" pitch and 94-pin dual-row layout support large-scale signal busing between closely stacked PCBs where 0.100" pitch connectors would consume excessive board area. The polarization feature ensures correct mating in automated assembly and field-service scenarios, reducing the risk of board damage from reversed insertion.

Frequently Asked Questions
How many total contacts does the TFM-147-12-LM-D-A-P-TR provide, and what pitch is used?
The TFM-147-12-LM-D-A-P-TR provides 94 total contact positions across 2 rows of 47 at a 0.050" (1.27 mm) pitch. This fine pitch doubles the contact density compared to 0.100" pitch connectors in the same linear board length, enabling high pin-count connections in space-constrained designs.
What is the significance of the Tiger Eye contact technology in the TFM-147-12-LM-D-A-P-TR for signal integrity?
SAMTEC Tiger Eye contacts use a dual-beam wiping design that maintains consistent contact force of approximately 30 gf per pin, producing contact resistance typically below 20 mΩ. This low and stable resistance is critical for high-speed digital signals where impedance discontinuities at connector interfaces can cause reflections above 1 GHz frequencies.
When should a designer use the polarized (-P) TFM-147-12-LM-D-A-P-TR rather than a non-polarized variant?
The -P polarization feature adds a physical keying tab that prevents the connector from being inserted 180 degrees out of orientation. It is particularly valuable for 94-pin dual-row assemblies where symmetric appearance could easily lead to reversed mating, which at logic voltages of 1.8 V or 3.3 V could instantly damage FPGA I/O banks or power rails connected to the interface.
How does the 0.050" pitch of the TFM-147-12-LM-D-A-P-TR compare to standard 0.100" pitch connectors for board area savings?
At 0.050" (1.27 mm) pitch, the TFM-147-12-LM-D-A-P-TR spans approximately 59.7 mm for 47 positions per row, whereas a 0.100" pitch connector with the same count would require 119.4 mm. This 50% reduction in connector length frees significant routing area on densely populated PCBs such as FPGA carrier boards and high-channel data acquisition modules.
