- 0.050 inch (1.27 mm) pitch dual-row layout with 141 positions providing 282 total contacts for ultra-high-density PCB interconnects
- Flush-mount (FM) termination minimizing connector height above the PCB for low-profile multi-board assemblies with tight vertical clearances
- Tiger Eye contact mechanism rated for 500+ reliable mating cycles ensuring long service life in high-reliability industrial and defense systems
- Tape-and-reel (-TR) packaging enabling seamless integration into automated SMT pick-and-place production lines
What is TFM-141-22-FM-D-A-P-TR used for?
The TFM-141-22-FM-D-A-P-TR is engineered for high-density board-to-board signal routing in FPGA mezzanine modules, industrial computing backplanes, and defense electronics where minimizing connector stack height is critical. Its 141-position dual-row 0.050 inch pitch configuration routes up to 282 signals per mated pair, supporting complex bus architectures on compact PCB form factors. The flush-mount termination and tape-and-reel packaging enable efficient automated SMT assembly in volume production of telecommunications and avionics systems.

Frequently Asked Questions
How does the flush-mount termination on TFM-141-22-FM-D-A-P-TR reduce board stack height versus standard surface-mount variants?
The flush-mount (FM) termination seats the contact tails at the PCB surface level without protruding downward, reducing the effective board stack height by 1 to 2 mm compared to standard gull-wing or J-lead surface-mount styles. In multi-PCB assemblies with total available clearance under 8 mm between boards, this saved vertical space allows engineers to incorporate thicker substrates or add additional signal layers without redesigning the enclosure.
What is the total contact capacity of TFM-141-22-FM-D-A-P-TR and which high-speed bus architectures benefit from it?
The TFM-141-22-FM-D-A-P-TR provides 141 dual-row positions at 0.050 inch (1.27 mm) pitch, yielding 282 individual contacts per mated connector pair. This capacity accommodates a 256-bit parallel data interface plus 26 additional power, ground, and control signals in a single connector footprint, benefiting FPGA-to-FPGA interconnects, high-speed DSP links, and memory controller interfaces in signal processing and imaging systems.
When should a designer choose TFM-141-22-FM-D-A-P-TR over a standard 0.100 inch pitch dual-row connector?
When a design requires more than 80 signal connections but board area constrains the connector landing zone to under 20 mm in length, the TFM-141-22-FM at 0.050 inch pitch achieves 141 positions in approximately half the PCB length that a 0.100 inch pitch alternative would occupy. This makes it the preferred choice for high-channel-count FPGA I/O expansion boards, imaging sensor interfaces, and radar signal processing modules where routing density outweighs the cost advantage of larger-pitch connectors.
