What are the key features of TFM-143-02-L-D-LC?
- 86-position dual-row vertical surface-mount configuration at 0.050" (1.27 mm) pitch enabling ultra-high-density board interconnects in space-constrained PCB assemblies
- Tiger Eye contact technology providing superior normal force and long contact wipe for reliable mating performance across repeated cycles in demanding environments
- Low-clearance (LC) design minimizing stack height above the PCB surface, ideal for applications requiring minimal z-axis profile in compact electronic assemblies
What is TFM-143-02-L-D-LC used for?
The TFM-143-02-L-D-LC is optimized for high-density board-to-board mating in compact electronic systems such as communication modules, military avionics, and ruggedized industrial controllers where 86 signals must be routed in a minimal PCB footprint. Its low-clearance vertical surface-mount design reduces the overall module height while maintaining robust Tiger Eye contact reliability. This part is well suited for applications demanding consistent electrical performance across -55°C to +125°C temperature ranges with vibration and shock resistance.

Frequently Asked Questions
How many positions does the TFM-143-02-L-D-LC offer and what pitch does it use?
The TFM-143-02-L-D-LC provides 86 positions arranged in a dual-row layout at 0.050" (1.27 mm) pitch. This gives 43 positions per row in a vertical surface-mount orientation, supporting high pin count interconnects in compact PCB designs common to telecommunications and defense electronics.
What does the LC designation mean for the TFM-143-02-L-D-LC and how does it affect board assembly?
The LC designation stands for Low-Clearance, indicating a reduced standoff height above the PCB surface compared to the standard TFM series. This reduced z-axis profile is critical in stacked board assemblies or slim enclosures where overall module thickness is constrained to less than 10 mm, enabling compact multi-board system designs.
Which high-reliability applications benefit most from the Tiger Eye contacts in the TFM-143-02-L-D-LC?
Tiger Eye contacts maintain reliable electrical connection at contact resistance below 20 milliohms through a minimum of 30 mating cycles even under mechanical shock and vibration. This makes the TFM-143-02-L-D-LC especially suitable for military avionics, radar signal processing boards, satellite payload electronics, and industrial automation systems operating in harsh environments with wide temperature swings of -55°C to +125°C.
Can the TFM-143-02-L-D-LC be used in automated PCB assembly lines, and is it available in bulk quantities?
Yes, the TFM-143-02-L-D-LC supports automated surface-mount assembly with standard reflow soldering profiles up to 260°C peak temperature. It is available from SAMTEC distributors in bulk quantities with typical lead times under 8 weeks, and its surface-mount footprint is compatible with standard pick-and-place equipment used in high-volume electronics manufacturing.
