What are the key features of TFM-144-04-STL-D-LC?
- Dual-row 144-position .050" (1.27 mm) pitch layout for high-density board interconnects
- STL straight-through-hole lead style enables secure mechanical anchoring during soldering and operation
- LC laser-cut contacts provide tighter dimensional tolerances for repeatable mating forces across all positions
What is TFM-144-04-STL-D-LC used for?
The TFM-144-04-STL-D-LC is used in dense backplane assemblies, server expansion cards, and industrial computing platforms that require a 144-pin dual-row connector with both SMT and through-hole mechanical retention. The STL lead style provides extra pull strength, making it suitable for connectors subject to vibration or repeated mating cycles. Its .050" pitch conserves board space while maintaining high signal counts.

Frequently Asked Questions
What distinguishes the STL lead style from other lead options in the TFM-144-04-STL-D-LC?
The STL lead style adds straight through-hole tails to the surface-mount body, providing mechanical anchoring to the PCB through 144 solder points. This dual retention method increases pull-out strength compared to standard SMT-only designs, which is critical in environments with vibration loads above 5 G or frequent mating cycles.
How does the .050" pitch on TFM-144-04-STL-D-LC compare to standard .100" pitch terminal strips?
The .050" (1.27 mm) pitch halves the spacing of a standard .100" pitch strip, allowing 144 positions in roughly the same linear board space that a 72-position .100" strip would require. This makes the TFM-144-04-STL-D-LC suitable for high-density mezzanine and backplane designs where routing over 100 differential pairs in a compact connector is necessary.
Which procurement sources carry the TFM-144-04-STL-D-LC and what lead times are typical?
The TFM-144-04-STL-D-LC is stocked by authorized SAMTEC distributors globally and is also available for factory order directly from SAMTEC with standard lead times typically ranging from 5 to 12 weeks for custom or high-volume orders. SAMTEC offers same-day shipping on in-stock quantities, and the LC laser-cut variant is a catalog option requiring no custom tooling charge.
