What are the key features of SFM-140-T2-ZZ-D-A-K-TR?
- 80-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch providing ultra-high contact density in a compact surface-mount footprint
- High-reliability gold-plated contacts designed for extended mating cycle life and stable low contact resistance across -55°C to +125°C operating range
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly for high-volume production runs with consistent placement accuracy
What is SFM-140-T2-ZZ-D-A-K-TR used for?
The SFM-140-T2-ZZ-D-A-K-TR is suited for high-density board-to-board and board-to-module stacking applications in FPGA daughtercards, industrial embedded computing, and defense electronics where 80-pin dual-row connectivity is required at 0.050" pitch. Its high-reliability construction ensures stable electrical performance across the full military and industrial temperature range, making it appropriate for avionics and harsh-environment telecom modules. The tape-and-reel format supports uninterrupted production at high volumes in automated SMT lines.

Frequently Asked Questions
How many positions does the SFM-140-T2-ZZ-D-A-K-TR provide and at what pitch?
The SFM-140-T2-ZZ-D-A-K-TR provides 80 total positions arranged in 2 rows of 40 contacts each, at a 0.050" (1.27 mm) pitch, occupying approximately 50 mm in board length. Gold-plated contacts deliver contact resistance typically below 20 milliohms and maintain electrical continuity over hundreds of mating cycles across the -55°C to +125°C temperature range.
Which FPGA or DSP module designs can take advantage of the 80-pin dual-row SFM-140-T2-ZZ-D-A-K-TR socket?
High-speed FPGA mezzanine cards, DSP processor modules, and mil-aero compute boards that route 60 to 80 differential or single-ended signals between layers benefit most from the SFM-140-T2-ZZ-D-A-K-TR. The 0.050" pitch allows 80 connections within a footprint that a 0.100" pitch connector would need double the board length to achieve, and the high-reliability contact design supports data rates exceeding 1 Gbps per channel in properly designed PCB stackups.
What procurement advantage does the tape-and-reel packaging of SFM-140-T2-ZZ-D-A-K-TR offer for volume builds?
The TR suffix on SFM-140-T2-ZZ-D-A-K-TR indicates it is supplied on standard tape-and-reel reels of typically 1000 or more parts, enabling direct feeding into automated SMT pick-and-place machines without manual loading or repackaging. For production runs of 500 units or more, this format typically reduces per-board connector placement time by 30 to 50 percent compared to tube-fed parts, and supports just-in-time delivery scheduling that lowers inventory carrying costs.
