What are the key features of TFM-137-32-SM-D-A-P-TR?
- 0.050-inch (1.27 mm) pitch dual-row surface-mount format provides 74 contacts in a compact footprint for high-density PCB designs
- Tiger Eye dual-beam wiping contact mechanism ensures robust electrical connection over 100 or more mating cycles
- Tape-and-reel packaging enables automated SMT pick-and-place assembly, reducing placement time in high-volume production
- Gold-plated contact surfaces minimize contact resistance to below 20 mΩ and prevent corrosion in harsh operating environments
What is TFM-137-32-SM-D-A-P-TR used for?
The TFM-137-32-SM-D-A-P-TR is used in high-density signal routing on FPGA evaluation boards, communication daughter cards, and modular industrial computing platforms requiring a reliable 0.050-inch pitch dual-row connector. Its surface-mount profile and tape-and-reel form factor also make it appropriate for telecom line cards and mil-aero avionics modules needing stable interconnection across wide temperature ranges.

Frequently Asked Questions
How many dual-row contacts does the TFM-137-32-SM-D-A-P-TR provide and at what pitch spacing?
The TFM-137-32-SM-D-A-P-TR provides 74 contacts arranged in 2 rows of 37 positions at a 0.050-inch (1.27 mm) pitch. This configuration delivers a high signal density of approximately 29 contacts per linear inch, making it effective for routing large signal buses between daughtercards and main boards in compact electronic systems.
In which high-reliability applications is the TFM-137-32-SM-D-A-P-TR preferred over a standard 0.100-inch pitch connector?
The TFM-137-32-SM-D-A-P-TR is preferred in military, aerospace, and test-and-measurement applications where the 0.050-inch pitch allows twice the contact density of 0.100-inch alternatives in the same PCB area. Its Tiger Eye contacts sustain reliable mating across at least 100 cycles and across temperatures from -55°C to +125°C, exceeding the durability needs of most commercial-grade connectors.
When selecting between the TFM-137-32-SM-D-A-P-TR and a 0.050-inch through-hole connector, what assembly considerations apply?
The surface-mount TFM-137-32-SM-D-A-P-TR eliminates the need for 74 drilled PCB holes, reducing board cost and increasing routing layers available under the connector footprint. However, reflow soldering must maintain a peak temperature below 260°C per IPC/JEDEC J-STD-020 standards, and the board must support solder paste printing at 1.27 mm pitch without bridging across the fine-pitch lands.
