Frequently Asked Questions
What is the contact pitch of the TFM-141-03-H-D-LC and how does it affect PCB layout density?
The TFM-141-03-H-D-LC features a 0.050" (1.27 mm) pitch between contacts. This fine pitch allows up to 82 contacts (41 positions, dual row) in a compact footprint, enabling high-density PCB designs where space is critical. Compared to standard 2.54 mm pitch connectors, this nearly halves the required board area.
Which high-reliability applications benefit most from the Tiger Eye contact technology in this terminal strip?
Tiger Eye contacts in the TFM-141-03-H-D-LC provide dual-beam wiping action that ensures reliable connections under vibration and thermal cycling conditions. This makes it well-suited for aerospace, military, and medical instrumentation requiring operation across a wide temperature range of -55°C to +125°C with consistent contact resistance below 30 mΩ.
How does the TFM-141-03-H-D-LC compare to a single-row TFM strip when selecting connectors for a compact backplane?
The dual-row D configuration of the TFM-141-03-H-D-LC accommodates 82 total contacts in the same board length as a single-row 41-pin strip, effectively doubling signal density per millimeter. For backplane designs needing more than 40 high-speed signal lines at 0.050" pitch, the dual-row variant is the preferred choice, reducing connector count and assembly cost.
