What are the key features of TFM-137-22-FM-D-A-P-TR?
- 0.050 inch (1.27 mm) pitch dual-row 37-position female mount terminal strip enabling 74 total contacts in a compact PCB footprint
- Tiger Eye contact system delivers high normal force per pin, ensuring stable low-resistance connections across hundreds of mating cycles
- Female mount (FM) termination with tape-and-reel (TR) packaging for compatibility with automated pick-and-place reflow assembly
What is TFM-137-22-FM-D-A-P-TR used for?
The TFM-137-22-FM-D-A-P-TR serves high-density interconnect requirements in telecommunications line cards, embedded computing backplanes, and test and measurement instrumentation where 74 signal channels must be routed within a 0.050 inch pitch dual-row footprint. The female mount termination allows direct mating with corresponding male terminal strips in board-stacking configurations. Tape-and-reel delivery simplifies high-volume automated assembly and reduces per-unit handling costs.

Frequently Asked Questions
What is the total contact count and pitch of the TFM-137-22-FM-D-A-P-TR?
The TFM-137-22-FM-D-A-P-TR has 37 positions per row in a dual-row layout, yielding 74 total contacts at a 0.050 inch (1.27 mm) pitch, delivering high contact density for signal-intensive board-to-board interconnect applications in compact electronic systems.
What does the FM suffix indicate in TFM-137-22-FM-D-A-P-TR and how does it affect mating compatibility?
FM stands for female mount, meaning this connector accepts corresponding male terminal strip pins in a board-stacking or card-edge configuration. The 0.050 inch pitch female contacts are engineered to maintain contact force above the minimum threshold over hundreds of mating cycles, preserving signal integrity across 74 signal positions.
How does TFM-137-22-FM-D-A-P-TR differ from TFM-150-22-FM-D-A-P-TR in circuit capacity?
The TFM-137-22-FM-D-A-P-TR offers 37 positions per row (74 total contacts) while the TFM-150-22 variant provides 50 positions per row (100 total contacts), both at 0.050 inch pitch. Designers choose the 37-position variant when fewer than 80 signals need routing and board length must be minimized compared to longer 50-position strips.
Which automated assembly processes are supported by the tape-and-reel packaging of TFM-137-22-FM-D-A-P-TR?
The TR suffix indicates tape-and-reel packaging compatible with industry-standard pick-and-place equipment, supporting reflow soldering at peak temperatures up to 260 degrees C. Reels typically contain several hundred connectors, enabling uninterrupted high-volume production runs without manual feeder reloading on fine-pitch 0.050 inch SMT lines.
