What are the key features of TFM-148-12-STL-D-A-P-TR?
- 96-position dual-row surface-mount tall (STL) contact style at .050" (1.27 mm) pitch provides maximum signal density with increased mated stack height for inter-board clearance
- Tiger Eye machined contact technology delivers consistent normal force and contact wiping across all 96 positions, maintaining low resistance through extended mating cycles
- Tape-and-reel (TR) packaging and SMD footprint enable automated pick-and-place assembly, supporting high-volume production of server, networking, and FPGA carrier board assemblies
What is TFM-148-12-STL-D-A-P-TR used for?
The TFM-148-12-STL-D-A-P-TR is designed for high-density mezzanine and board-to-board applications in server computing, high-performance networking, and FPGA carrier boards where 96 signal positions at .050" pitch and a tall SMD profile are required to accommodate inter-board component clearance. The STL (surface-mount tall) configuration is specifically chosen when daughter-card components require additional vertical clearance between stacked boards without increasing the footprint. Tape-and-reel delivery ensures this 96-position connector can be placed consistently and efficiently on automated SMT production lines.

Frequently Asked Questions
What does the STL designation on TFM-148-12-STL-D-A-P-TR mean and when should it be selected over standard SMD variants?
The STL designation stands for surface-mount tall, indicating a taller contact post height than the standard surface-mount variant. Engineers select TFM-148-12-STL-D-A-P-TR when mezzanine-stacked boards have tall components such as capacitors or heat sinks requiring 5 mm or more of vertical clearance between board surfaces, while still maintaining the .050" (1.27 mm) pitch with 96 signal positions in a dual-row layout.
How does TFM-148-12-STL-D-A-P-TR handle signal integrity across its 96 positions in high-speed digital designs?
TFM-148-12-STL-D-A-P-TR uses Tiger Eye precision-machined contacts that maintain contact resistance typically below 20 milliohms per pin across all 96 positions. The consistent normal force applied by each Tiger Eye socket minimizes intermittent contact events, supporting reliable signal integrity for high-speed differential pairs and single-ended signals in FPGA-to-FPGA and processor-to-memory mezzanine interconnect designs.
Can TFM-148-12-STL-D-A-P-TR replace TFM-148-12-S-D-A-P-TR in existing designs and what is the key difference?
TFM-148-12-STL-D-A-P-TR and TFM-148-12-S-D-A-P-TR share the same .050" (1.27 mm) pitch, dual-row layout, and 96-position count, but differ in mated stack height. The STL variant sits taller, adding approximately 1 mm to 3 mm of inter-board spacing. Substituting STL for the standard variant is feasible when the PCB footprint and pad pattern are identical, but the enclosure or mating board design must accommodate the additional board-to-board height to avoid mechanical interference.
