What are the key features of TFM-141-04-L-D-LC?
- 82-position dual-row configuration on 0.050" (1.27 mm) pitch delivers industry-leading signal density for high pin-count board interconnects
- Tiger Eye contact technology ensures reliable wiping action and secure retention across hundreds of mating cycles in vibration or shock environments
- Low-clearance (LC) low-profile surface-mount design minimizes PCB-to-PCB stack height for slim embedded and mezzanine board assemblies
What is TFM-141-04-L-D-LC used for?
The TFM-141-04-L-D-LC is ideal for high-density mezzanine card interconnects, FPGA evaluation boards, and networking line cards that require 82 signals routed in a compact 0.050" pitch footprint. Its low-clearance profile suits slim server blade modules, telecom equipment chassis, and embedded computing platforms where reduced board-to-board spacing is a design requirement. The Tiger Eye contact system further qualifies this connector for military electronics, aerospace data recorders, and industrial automation systems where long-term reliability under vibration is critical.

Frequently Asked Questions
What position count and row configuration does the TFM-141-04-L-D-LC use, and how does its pitch compare to standard 0.100" headers?
The TFM-141-04-L-D-LC provides 82 positions in a dual-row (2x41) layout on a 0.050" (1.27 mm) pitch, which is exactly half the spacing of a standard 0.100" (2.54 mm) header. This halved pitch doubles the achievable signal density per board length, enabling engineers to route 82 signals in the same PCB area that a conventional 0.100" header would use for only 41 positions.
Which board-to-board interconnect scenarios justify the Tiger Eye contact system in the TFM-141-04-L-D-LC over standard stamped contacts?
High-cycle applications such as FPGA mezzanine cards, test fixture interfaces, and aerospace avionics boards benefit most from the Tiger Eye contact system, which delivers a positive wiping action that maintains reliable contact resistance across hundreds of mate-unmate cycles. The contact geometry is engineered to tolerate vibration and shock loads that would cause intermittent failures in conventional stamped-contact terminal strips, making it the preferred choice for 82-position interconnects in harsh environments.
In a slim server blade design, how does the low-clearance profile of TFM-141-04-L-D-LC affect board stack height compared to a standard TFM series part?
The low-clearance (LC) variant of the TFM-141-04-L-D-LC reduces the above-board connector profile by several tenths of a millimeter compared to the standard TFM body, directly shrinking the minimum board-to-board gap in a mated stack. For slim server blade or mezzanine configurations where 82 signals must cross a board interface within a chassis slot constrained to less than 10 mm of total stack height, the LC design can be the difference between a compliant and non-compliant mechanical envelope.
