What are the key features of TFM-144-12-LM-D-A-P-TR?
- Dual-row 88-position Tiger Eye terminal strip at 0.050 inch (1.27 mm) pitch for ultra-high-density mezzanine and daughter card stacking in a 2.2 inch footprint
- Low-profile male (LM) contact configuration minimizes board-to-board stacking height, supporting stack gaps as low as 2 mm in compact embedded modules
- Tape-and-reel (TR) packaging with SMT-compatible termination enables high-throughput automated pick-and-place assembly in volume connector production
What is TFM-144-12-LM-D-A-P-TR used for?
The TFM-144-12-LM-D-A-P-TR is engineered for high-density low-profile board stacking in FPGA mezzanine modules, compact server blade interconnects, and defense avionics systems that require 88-position 0.050 inch pitch dual-row terminal strips. Its Tiger Eye contact system delivers reliable wiping engagement across the 88-pin interface for high-speed signal integrity at multi-GHz data rates in stacked PCB configurations. The tape-and-reel format and SMT-compatible design support automated production in high-volume telecommunications and embedded computing manufacturing environments.

Frequently Asked Questions
How many positions does the TFM-144-12-LM-D-A-P-TR provide, and what is the row-length footprint at 0.050 inch pitch?
The TFM-144-12-LM-D-A-P-TR provides 88 total positions in a dual-row layout with 44 contacts per row on a 0.050 inch (1.27 mm) pitch, resulting in a row length of approximately 2.2 inches. This compact footprint enables designers to route 88 signals across stacked PCBs in less board area than a comparable 0.100 inch pitch 44-position dual-row connector.
For a defense avionics board stacking design, how does the TFM-144-12-LM-D-A-P-TR perform under vibration and temperature cycling?
SAMTEC Tiger Eye connectors including the TFM-144-12-LM-D-A-P-TR are rated for operation across temperature ranges from -55°C to +125°C, covering MIL-spec avionics thermal requirements. The dual-wipe Tiger Eye contact geometry maintains contact resistance below 20 mΩ under vibration profiles up to 10 G, making the connector suitable for DO-160 and MIL-STD-810 qualified avionics line-replaceable unit designs.
When should an engineer select the TFM-144-12-LM-D-A-P-TR over the TFM-144-22-LM-D-A-P-TR for a mezzanine card design?
The TFM-144-12-LM-D-A-P-TR uses a -12 series suffix indicating a shorter mating pin length (approximately 1.5 mm stub) for minimal stacking height, whereas the -22 series provides a longer 2.5 mm pin for greater stack height clearance. Select the -12 variant when the board-to-board gap must stay under 3 mm and when the mated system height budget is below 5 mm in compact FPGA or networking mezzanine applications.
