What are the key features of TFM-122-03-L-D-LC?
- Proprietary Tiger Eye contact design for enhanced mating force and oxide-wiping action across 44 positions
- 0.050 inch (1.27 mm) pitch dual-row layout enabling high-density signal routing in compact SMT footprints
- Low-clearance (LC) configuration minimizing board-to-board stacking height for space-constrained electronic assemblies
What is TFM-122-03-L-D-LC used for?
The TFM-122-03-L-D-LC is suited for high-density mezzanine and board-to-board interconnects in network switching, data storage, and embedded computing modules where 0.050 inch pitch SMT connectors with minimal stacking height are required. Its Tiger Eye contact technology ensures reliable low-resistance connections across 44 positions, even in thermally cycling environments. The low-clearance design reduces overall assembly height, benefiting slim-profile enclosures and ruggedized equipment.

Frequently Asked Questions
How does the low-clearance (LC) feature of the TFM-122-03-L-D-LC benefit board-to-board stacking height?
The low-clearance designation means the TFM-122-03-L-D-LC achieves a reduced board-to-board mating height, typically below standard TFM series stacking heights. For equipment where PCB assemblies must fit within tight enclosures, this reduction of several tenths of a millimeter across 44 positions enables more compact multi-board stacking configurations.
What distinguishes the Tiger Eye contact in the TFM-122-03-L-D-LC from standard beam contacts?
The Tiger Eye contact geometry creates higher contact normal force and a controlled wiping motion during engagement, removing surface oxide layers across all 44 positions. This results in lower and more stable contact resistance compared to standard single-beam contacts, improving signal integrity at 0.050 inch (1.27 mm) pitch over multiple mating cycles.
In which high-density computing or network applications does the TFM-122-03-L-D-LC deliver the most value?
This 44-position, 0.050 inch pitch SMT connector is particularly effective in network line cards, FPGA daughter boards, and high-speed data storage modules where tight PCB real estate demands that 44 or more signals be routed through a minimal footprint with reliable high-cycle mating performance.
How does the dual-row layout of the TFM-122-03-L-D-LC compare to single-row alternatives for the same pin count?
The dual-row arrangement halves the connector length needed to accommodate 44 positions compared to a single-row layout at 0.050 inch (1.27 mm) pitch. This reduces the board footprint length by approximately 22 positions worth of pitch, leaving more PCB area for routing or other components in space-constrained designs.
