What are the key features of TFM-138-32-SM-D-A-P-TR?
- High-reliability Tiger Eye contact system on 0.050 inch pitch supports 138 dual-row positions for dense signal routing
- Surface-mount termination in tape and reel (TR) packaging for fully automated SMT pick-and-place assembly
- Dual-row layout doubles contact density versus single-row strips, reducing overall connector length for compact PCB designs
What is TFM-138-32-SM-D-A-P-TR used for?
The TFM-138-32-SM-D-A-P-TR is suited for board-to-board and wire-to-board signal interconnect in test and measurement systems, embedded computing modules, and defense electronics that require high contact count within a compact 0.050 inch pitch footprint. Its 138-position dual-row configuration accommodates complex multi-bus interfaces, including parallel data buses, control signals, and power distribution on a single connector. The tape and reel packaging supports high-volume automated SMT assembly, making it a practical choice for production-scale deployments.

Frequently Asked Questions
How many signal positions does TFM-138-32-SM-D-A-P-TR provide and what pitch are they arranged on?
The TFM-138-32-SM-D-A-P-TR offers 138 positions in a dual-row arrangement on a 0.050 inch (1.27 mm) pitch. This configuration accommodates 69 pairs of signals or a large number of independent lines, making it well suited for dense parallel bus interfaces in compute boards and FPGA development platforms where board space is limited.
For a high-volume PCB production run, how does the TFM-138-32-SM-D-A-P-TR packaging aid assembly efficiency?
The TR suffix on TFM-138-32-SM-D-A-P-TR denotes tape and reel packaging, which is directly compatible with automated SMT pick-and-place machines running at speeds of thousands of placements per hour. The SM surface-mount termination style enables standard reflow soldering, reducing manual handling and improving placement accuracy on a 0.050 inch pitch for 138-position dual-row connectors in volume production.
When is TFM-138-32-SM-D-A-P-TR a preferable alternative to a higher-pitch connector in space-constrained board designs?
When PCB real estate is limited and the design demands 138 or more signal connections, the TFM-138-32-SM-D-A-P-TR's 0.050 inch pitch consumes roughly half the linear board length of a comparable 0.100 inch pitch connector. This makes it the preferred choice in compact FPGA or SoC carrier boards, where saving even 5 mm to 10 mm of connector length can allow routing of additional power planes or decoupling capacitors in the saved area.
