Key Features
- 74-position dual-row layout on 0.050" (1.27 mm) pitch enabling high-density parallel signal routing across 37 rows
- Tiger Eye contact geometry delivering consistent normal force and contact resistance below 20 milliohms per contact
- Press-fit (P) tail termination creating solderless gas-tight connections for rework-sensitive or high-vibration assemblies
- Tape-and-reel (TR) packaging enabling automated pick-and-place on standard SMT production lines at high volume
Applications
The TFM-137-22-LM-D-A-P-TR is designed for high-density mezzanine, FPGA daughter-card, and backplane interconnections in telecommunications equipment, defense systems, and high-performance computing platforms. Its 74 Tiger Eye contacts on a 0.050 inch pitch allow dense parallel bus routing where board area is tightly constrained. The press-fit termination option eliminates thermal stress on sensitive adjacent components during board assembly.

Frequently Asked Questions
How many contacts does TFM-137-22-LM-D-A-P-TR provide and on what row arrangement?
TFM-137-22-LM-D-A-P-TR provides 74 contacts arranged in a dual-row (D) configuration on a 0.050 inch (1.27 mm) pitch. The 37-row dual-row layout spans approximately 46 mm in length, supporting wide parallel data buses or multi-lane high-speed signal routing on a single connector.
When is TFM-137-22-LM-D-A-P-TR a better choice than a solder-terminated Tiger Eye strip for defense applications?
In defense and aerospace assemblies subject to shock and vibration exceeding 10 g, the press-fit P termination of TFM-137-22-LM-D-A-P-TR produces a mechanically superior, solderless gas-tight joint compared to standard solder tails. This eliminates solder fatigue cracking over 74 contact positions while enabling board removal and reinsertion without rework.
What differentiates TFM-137-22-LM-D-A-P-TR from TFM-139-22-S-D-A-P-TR in terms of contact count and mating interface?
TFM-137-22-LM-D-A-P-TR has 74 contacts while TFM-139-22-S-D-A-P-TR has 78 contacts, both on the same 0.050 inch pitch dual-row layout. Designers select between them based on the required bus width: 74 contacts on TFM-137 versus 78 on TFM-139, differing by 4 positions or 2 additional rows per side.
