What are the key features of TFM-146-02-S-D-LC?
- 92 contacts in a dual-row vertical surface-mount configuration at 0.050-inch (1.27 mm) pitch for maximum contact density on SMT PCB assemblies
- LC (low-crosstalk) variant with optimized contact spacing reduces inter-channel coupling on adjacent differential signal pairs above 100 MHz
- Tiger Eye contact geometry provides secure mating retention and consistent wiping action to maintain low contact resistance over extended temperature and vibration cycles
What is TFM-146-02-S-D-LC used for?
The TFM-146-02-S-D-LC is designed for high-density SMT board-to-board interconnect in data center switching line cards, telecommunications backplane assemblies, and high-performance computing modules where minimizing board real estate while preserving signal integrity is critical. The LC contact spacing makes it well suited for designs carrying LVDS, SERDES, or high-speed differential buses between mezzanine cards at signal rates exceeding 100 MHz. Surface-mount reflow compatibility allows it to be placed alongside other SMT components in fully automated pick-and-place assembly processes, simplifying manufacturing of complex multi-layer PCBs.

Frequently Asked Questions
How many positions does TFM-146-02-S-D-LC offer, and what mounting style does it use?
The TFM-146-02-S-D-LC is a 92-position dual-row vertical surface-mount connector at 0.050-inch (1.27 mm) pitch. The SMT vertical footprint allows reflow soldering alongside other surface-mount components, eliminating the need for through-hole drilling and enabling high-density placement in multilayer PCB designs used in telecom and data center equipment.
For a high-speed SERDES interface board, what benefit does the LC suffix provide in TFM-146-02-S-D-LC?
The LC (low-crosstalk) suffix indicates optimized contact geometry that reduces capacitive and inductive coupling between adjacent signal pairs. For differential signals such as SERDES or PCIe lanes running at 1 Gbps to 10 Gbps, the LC configuration maintains inter-pair isolation, preserving eye margin and bit error rates that would otherwise degrade on a standard 0.050-inch pitch connector with 92 contacts packed at high density.
How does TFM-146-02-S-D-LC compare to a through-hole TFM equivalent for automated board assembly?
The surface-mount (S) variant TFM-146-02-S-D-LC eliminates the need for through-hole drilling, reducing PCB fabrication cost on 92-pin boards. It can be placed by standard SMT pick-and-place equipment and reflowed in a single oven pass alongside 0402, 0603, and BGA components, cutting assembly time per board. In contrast, a through-hole TFM equivalent requires a separate wave-solder or hand-solder step, adding labor cost for high-volume production runs.
