What are the key features of TFM-148-12-SM-D-A-P-TR?
- 0.050" (1.27 mm) pitch dual-row 48-position surface mount configuration delivering 96 contacts in a compact layout
- Surface mount (SM) termination enabling reflow soldering without through-hole vias, streamlining multilayer PCB fabrication
- Tiger Eye contact system providing reliable low contact resistance across 96 positions for high-integrity signal and power distribution
What is TFM-148-12-SM-D-A-P-TR used for?
The TFM-148-12-SM-D-A-P-TR is used in high-density mezzanine board-to-board connections for server blades, FPGA development platforms, and embedded computing modules where 96 contacts at 0.050" pitch consolidate extensive signal routing into a single connector. Its surface mount termination supports reflow solder assembly and eliminates drilling for 96 vias, reducing PCB cost and enabling finer trace routing on adjacent layers. Tape-and-reel packaging makes it compatible with high-speed automated pick-and-place production lines.

Frequently Asked Questions
How does TFM-148-12-SM-D-A-P-TR differ from TFM-148-22-S-D-A-P-TR in termination method and PCB assembly impact?
The TFM-148-12-SM-D-A-P-TR uses surface mount (SM) termination, while TFM-148-22-S-D-A-P-TR uses a straight through-hole (S) termination. Both are dual-row 48-position connectors at 0.050" (1.27 mm) pitch with 96 total contacts, but the surface mount variant eliminates the need for 96 drilled vias, reducing PCB fabrication cost and enabling placement on boards with dense inner-layer routing. Surface mount connectors are also compatible with fully automated reflow soldering at 260°C peak.
What PCB pad and footprint requirements should engineers plan for when designing with TFM-148-12-SM-D-A-P-TR?
The TFM-148-12-SM-D-A-P-TR requires a dual-row surface mount pad pattern at 0.050" (1.27 mm) pitch along both rows, spanning approximately 60 mm in length for 48 positions per row. Engineers should include a solder paste stencil aperture sized for each pad to ensure consistent joint formation during reflow at 260°C peak temperature. The SAMTEC recommended land pattern and solder mask design should be followed to prevent bridging between pads at the 1.27 mm pitch spacing.
Which industrial or computing applications benefit most from deploying TFM-148-12-SM-D-A-P-TR over lower-density connector alternatives?
Applications requiring more than 80 simultaneous connections on a compact PCB benefit most from TFM-148-12-SM-D-A-P-TR, including high-speed data acquisition cards, FPGA daughter board interfaces, and industrial fieldbus backplanes. Replacing two 48-contact 0.100" connectors with a single 96-contact 0.050" pitch unit can reduce connector footprint by 50%, freeing PCB area for additional circuitry. This is especially valuable in 3.3 V or 5 V logic systems on boards with area budgets under 100 cm².
