What are the key features of TFM-145-13-STL-D?
- 90 positions in dual-row .050" (1.27 mm) pitch Tiger Eye terminal strip for very high pin-count signal and power routing
- Tiger Eye contact system provides 30% higher normal force than standard friction contacts, ensuring reliable mating at up to 100 mating cycles
- Through-hole lead (STL) termination delivers mechanical strength and vibration resistance superior to SMT equivalents in rugged field-deployed equipment
What is TFM-145-13-STL-D used for?
The TFM-145-13-STL-D is designed for high-density mezzanine, daughter card, and backplane interconnects in FPGA systems, radar signal processors, and rugged military electronics requiring 90 signal paths in a compact .050" pitch footprint. The Tiger Eye contact system ensures reliable low-resistance mating in temperature ranges from -55°C to +125°C, supporting harsh environment applications. Its through-hole solder tails provide the mechanical robustness needed for airborne and ground-vehicle-mounted electronics subject to vibration and shock.

Frequently Asked Questions
What is the position count and pitch of the TFM-145-13-STL-D, and how does it compare to a 0.100" pitch equivalent?
The TFM-145-13-STL-D provides 90 positions in a dual-row layout at .050" (1.27 mm) pitch, fitting 45 contacts per row within approximately 2.25 inches of board length. An equivalent 0.100" pitch dual-row strip for 90 positions would require approximately 4.5 inches — twice the board edge length — making the .050" pitch variant essential for high-density FPGA and radar signal processing boards where space is at a premium.
How does the Tiger Eye contact system in TFM-145-13-STL-D improve reliability compared to standard beam contacts?
The Tiger Eye contact generates approximately 30% higher normal mating force than standard dual-beam contacts at the same .050" pitch, maintaining contact resistance below 15 mΩ even after 100 mating cycles. This is critical in field-replaceable module designs where connectors are mated and unmated during maintenance, ensuring signal integrity is preserved across mil-spec temperature extremes from -55°C to +125°C.
When is the through-hole STL termination of TFM-145-13-STL-D preferred over a surface mount termination for a rugged avionics design?
The through-hole STL termination is preferred when the assembly must withstand vibration levels above 10 g or shock loads above 50 g as specified by MIL-STD-810. Plated through-hole solder joints in a 90-position dual-row footprint resist solder fatigue significantly better than SMT fillet joints under cyclic thermal stress from -55°C to +125°C, reducing field failure rates in avionics line replaceable units by an estimated 40% compared to equivalent SMT terminations.
