What are the key features of TFM-143-05-S-D-LC?
- Single-row 43-position terminal strip at 0.050" (1.27 mm) pitch enabling a compact linear interconnect footprint for high pin-count signal routing
- Tiger Eye low-insertion-force contact design supports 200+ mating cycles for field-replaceable module applications
- Gold-plated contacts with 30 µin finish ensure low stable contact resistance and corrosion resistance across extended temperature ranges
What is TFM-143-05-S-D-LC used for?
The TFM-143-05-S-D-LC is used in high-density board-to-board and board-to-cable interconnect designs for defense electronics, aerospace avionics, and industrial automation where 43 signal lines must be routed in a single-row strip at 0.050" pitch. Its compact linear layout is well suited for edge-card and mezzanine board configurations that demand reliable connectivity in vibration-prone environments. The low-insertion-force Tiger Eye contact system reduces assembly forces and extends connector service life in frequently serviced equipment.

Frequently Asked Questions
How does TFM-143-05-S-D-LC differ from dual-row TFM variants with a similar position count?
TFM-143-05-S-D-LC is a single-row 43-position strip, providing 43 total contacts compared to dual-row variants that would double contact count in approximately the same board-length footprint at 0.050" pitch. Single-row layout is preferred when PCB routing channels are aligned in one direction or when clearance height prevents stacking dual-row connectors.
What contact plating and cycle life does TFM-143-05-S-D-LC support in military avionics designs?
The connector uses 30 µin gold over nickel plating on each of its 43 contacts, supporting a minimum of 200 mating cycles with contact resistance remaining below 20 mΩ. This makes TFM-143-05-S-D-LC well suited for military avionics line-replaceable unit (LRU) applications operating from -55°C to +125°C under vibration and shock.
For a test fixture needing a low-force 43-pin edge connector, why is TFM-143-05-S-D-LC an effective choice?
The Tiger Eye contact geometry reduces mating force per pin compared to standard tuning-fork contacts, so a 43-position strip like TFM-143-05-S-D-LC can be engaged by hand without special tooling. At 0.050" pitch the strip spans roughly 54.6 mm, fitting standard test fixture channel widths while accommodating high-cycle test operations exceeding 200 insertions.
