What are the key features of TFM-135-01-STL-D-A-P-TR?
- 70-position dual-row surface-mount Tiger Eye terminal strip at 0.050" (1.27 mm) pitch for high-density board-to-board interconnects in compact, high-pin-count PCB assemblies
- Through-lead (STL) surface-mount termination providing stronger solder joint anchoring than standard gull-wing leads, enhancing mechanical robustness in vibration-prone environments
- Tape-and-reel (TR) packaging and surface-mount design compatible with automated pick-and-place SMT assembly processes, supporting reflow profiles up to 260°C for high-volume production
What is TFM-135-01-STL-D-A-P-TR used for?
The TFM-135-01-STL-D-A-P-TR is optimized for high-density board-to-board mating in telecommunications equipment, military electronics, and medical imaging systems where 70 signals at 0.050" pitch must be reliably interconnected with enhanced solder joint strength. The STL through-lead termination improves pull-out resistance compared to standard surface-mount pads, making this part suitable for modules subjected to mechanical stress during handling or operation. Tape-and-reel packaging enables efficient high-volume automated assembly with consistent placement accuracy.

Frequently Asked Questions
What does the STL termination style in TFM-135-01-STL-D-A-P-TR mean for PCB assembly strength?
STL (short through-lead) is a surface-mount termination variant where the contact leads extend slightly through the PCB solder pads, increasing solder joint surface area and pull-out strength compared to standard surface-mount leads. This termination style improves mechanical robustness in connectors carrying 70 pins at 0.050" (1.27 mm) pitch, particularly where the mated connector assembly experiences lateral cable strain or vibration loads exceeding 5 G in industrial or transportation environments.
How many positions does the TFM-135-01-STL-D-A-P-TR accommodate and at what pitch?
The TFM-135-01-STL-D-A-P-TR provides 70 positions in a dual-row configuration (35 per row) at 0.050" (1.27 mm) pitch. This high pin count in a compact 0.050" pitch footprint is approximately half the board area of an equivalent 0.100" pitch 70-pin connector, enabling denser PCB layouts for telecom line cards, FPGA breakout boards, and multi-channel data acquisition modules.
Which operational environments are most suitable for the TFM-135-01-STL-D-A-P-TR Tiger Eye contacts?
Tiger Eye contacts in the TFM-135-01-STL-D-A-P-TR are engineered for demanding environments including defense avionics, satellite electronics, and industrial control systems requiring reliable connection across temperatures from -55°C to +125°C. The contact geometry maintains contact resistance below 20 milliohms through at least 30 mating cycles under shock loads above 50 G and vibration levels up to 20 G, exceeding performance of standard 0.050" pitch bifurcated contacts.
Is the TFM-135-01-STL-D-A-P-TR compatible with standard SMT reflow processes and automated assembly?
Yes, the TFM-135-01-STL-D-A-P-TR comes in tape-and-reel (TR) format and is compatible with automated pick-and-place equipment using standard 12 mm or 16 mm carrier tape. Its surface-mount STL leads support standard lead-free reflow soldering with peak temperatures up to 260°C per IPC/JEDEC J-STD-020, making it suitable for volume PCB assembly lines producing communication modules, industrial controllers, and defense subsystems.
