What are the key features of TFM-137-12-STL-D-A-P-TR?
- 0.050 inch (1.27 mm) pitch dual-row Tiger Eye terminal strip with 74 total positions and straddle-mount (STL) PCB termination for edge-launch applications
- High-reliability Tiger Eye contact technology delivering consistent low-ohm mating resistance from -55°C to +125°C operating range
- Tape-and-reel (TR) packaging for seamless integration with automated SMT pick-and-place equipment in high-volume manufacturing
What is TFM-137-12-STL-D-A-P-TR used for?
TFM-137-12-STL-D-A-P-TR is suited for edge-mounted board-to-board interconnect scenarios such as PCIe riser cards, backplane interfaces, and rugged embedded computing modules where straddle-mount attachment eliminates the need for through-hole drilling. The 74-contact dual-row layout enables simultaneous routing of high-speed differential pairs, single-ended signals, and power within a 0.050 inch pitch footprint. Its tape-and-reel form factor supports high-volume automated assembly in defense electronics, telecommunications, and industrial control platforms.

Frequently Asked Questions
What does the STL suffix indicate about TFM-137-12-STL-D-A-P-TR mounting style?
The STL suffix designates a straddle-mount termination where the connector legs straddle the PCB edge rather than requiring drilled holes or conventional surface-mount pads. This allows TFM-137-12-STL-D-A-P-TR to mate directly at a board edge with 74 contact positions at 0.050 inch pitch, saving vertical height and eliminating through-hole drilling operations in the PCB stack.
For a compact rugged embedded computing module, how many signals can TFM-137-12-STL-D-A-P-TR route?
TFM-137-12-STL-D-A-P-TR provides 74 total contact positions in a dual-row configuration at 0.050 inch pitch, supporting up to 74 individual signal, power, or ground connections per mated pair. This capacity covers full PCIe x4 differential lanes plus auxiliary control signals, or mixed-signal data buses needed in rugged SBC and FPGA module designs operating across -55°C to +125°C.
When should an engineer choose TFM-137-12-STL-D-A-P-TR over a standard through-hole connector of similar pin count?
Engineers choose the STL straddle-mount variant when PCB thickness constraints prevent via drilling or when board-edge signal launch is required for right-angle signal routing in compact enclosures. TFM-137-12-STL-D-A-P-TR delivers 74 contacts at 0.050 inch pitch without requiring any drilled holes, reducing laminate cost and enabling thinner PCB designs below 1.6 mm that are incompatible with standard through-hole connector footprints.
