What are the key features of TFC-141-02-LM-D-A?
- 82-position dual-row SMT terminal strip at 0.050" (1.27 mm) pitch enabling wide parallel bus or multi-channel signal routing
- Tiger Eye contact design for reliable wiping action, low insertion force, and stable contact resistance across all 82 positions
- Low-profile male (LM) SMT configuration optimized for space-constrained board stacking and mezzanine card designs
- Cost-effective Tiger Eye series design suitable for high-volume production with no compromise on interconnect reliability
What is TFC-141-02-LM-D-A used for?
The TFC-141-02-LM-D-A is designed for wide-bus board-to-board interconnect in FPGA development boards, high-performance computing modules, and advanced industrial control systems requiring 82 simultaneous signal channels. Its 0.050" pitch dual-row layout concentrates 82 contacts into a compact strip, making it practical for backplane connectors, memory expansion interfaces, and data acquisition front-ends where maximizing channel count per millimeter is critical. The cost-effective design supports high-volume production in telecommunications and defense electronics where dense, reliable interconnect is required at scale.

Frequently Asked Questions
What is the maximum channel count and pitch of the TFC-141-02-LM-D-A, and what bus widths can it support?
The TFC-141-02-LM-D-A provides 82 positions at a 0.050" (1.27 mm) pitch in a dual-row layout, supporting wide parallel buses of up to 82 signals. This accommodates configurations such as a 64-bit data bus plus additional control, power, and ground signals in a single connector, making it suitable for FPGA expansion boards and high-performance embedded computing interconnects.
How does the 82-position TFC-141-02-LM-D-A fit on a PCB compared to a connector with twice the pitch?
At 0.050" (1.27 mm) pitch, TFC-141-02-LM-D-A places 82 contacts in approximately 2.6 inches of body length in a dual-row arrangement. A comparable single-row connector at 0.100" (2.54 mm) pitch for 82 positions would extend to over 8 inches, making the fine-pitch dual-row design roughly 3 times more space-efficient, which is critical for dense PCB layouts in FPGA modules and backplane cards.
For an FPGA I/O expansion board requiring more than 64 signal channels, why is TFC-141-02-LM-D-A a practical choice?
The TFC-141-02-LM-D-A provides 82 positions — enough for a 64-bit parallel bus plus 18 additional lines for control, power, and ground signals — all within a compact 0.050" pitch footprint. Its low-profile male SMT form factor is compatible with standard FPGA breakout PCB designs, and the Tiger Eye contact technology ensures signal integrity across all 82 channels even after repeated board insertions during prototyping and testing.
