What are the key features of TFM-141-12-FM-D-A-P-TR?
- Tiger Eye flat-mount (FM) contact system provides low-profile SMT attachment with reliable electrical performance and extended mating cycle life across 82 dual-row positions
- 0.050" (1.27 mm) pitch dual-row layout with 82 contacts enables ultra-high signal density on compact PCBs for telecom, computing, and industrial designs
- Polarization feature and tape-and-reel (TR) packaging enable error-free orientation and high-speed automated pick-and-place assembly in volume SMT production
What is TFM-141-12-FM-D-A-P-TR used for?
TFM-141-12-FM-D-A-P-TR serves high-density board-to-board interconnect requirements in advanced computing modules, network switching platforms, and modular mil-aero electronics where 82 signals must be reliably routed in a minimal PCB footprint. The flat-mount termination style enables flush PCB placement, reducing total assembly height for slim stacked-board architectures. Tape-and-reel packaging ensures seamless integration into high-volume SMT manufacturing lines while the polarization key prevents mis-mating in multi-connector system layouts.

Frequently Asked Questions
How many contacts does TFM-141-12-FM-D-A-P-TR have, and how are they arranged in the dual-row configuration?
TFM-141-12-FM-D-A-P-TR provides 82 total contact positions arranged in a dual-row surface-mount configuration with 41 contacts per row, all on a 0.050" (1.27 mm) pitch. This dense arrangement accommodates 82 independent signal or power paths in a PCB footprint of roughly 53 mm in row length, ideal for computing and telecom board-to-board interfaces.
What distinguishes the flat-mount (FM) termination of TFM-141-12-FM-D-A-P-TR from standard SMT terminations in low-clearance stacked-board designs?
The flat-mount (FM) termination style on TFM-141-12-FM-D-A-P-TR places the solder tails flush to the PCB surface, minimizing the connector's height profile to enable board-to-board stack heights potentially below 3 mm. Standard SMT terminations may extend slightly below the PCB plane, whereas the FM style eliminates this protrusion, giving designers tighter control over vertical clearance in slim stacked-board assemblies.
For multi-connector PCB layouts at 1.27 mm pitch, how does the polarization of TFM-141-12-FM-D-A-P-TR prevent costly assembly errors?
The polarization key on TFM-141-12-FM-D-A-P-TR physically blocks 180-degree mis-insertion of the 82-pin dual-row connector, preventing reversed signal and power connections that could damage ICs operating at 1.8 V or 3.3 V logic. On dense PCBs with multiple identically-sized connectors spaced within 5 mm of each other, this mechanical keying is the primary safeguard against costly rework.
How does TFM-141-12-FM-D-A-P-TR compare to 2.00 mm pitch dual-row connectors for FPGA module carrier board interfaces?
At 1.27 mm pitch, TFM-141-12-FM-D-A-P-TR provides 82 contacts in approximately 53 mm of row length, while a 2.00 mm pitch connector for the same contact count would require roughly 82 mm — about 55% more PCB length. This size advantage makes TFM-141-12-FM-D-A-P-TR the preferred choice for FPGA carrier boards where module footprint reduction directly impacts system integration density.
