What are the key features of TFM-143-22-STL-D-A-P-TR?
- Tiger Eye contact geometry ensures superior wiping action and gas-tight connections at 0.050" pitch with gold plating for long-term signal reliability
- Dual-row 86-position (43 per row) layout delivers high pin-count density in a compact fine-pitch footprint for complex board-to-board interfaces
- Short tail length (STL) variant provides precise insertion depth control for accurate PCB mounting in through-hole or controlled-depth SMT configurations
What is TFM-143-22-STL-D-A-P-TR used for?
The TFM-143-22-STL-D-A-P-TR serves high-density signal interconnect needs in advanced computing platforms, ruggedized military electronics, and precision test and measurement systems requiring 86-position fine-pitch connectivity. Its short tail length allows controlled insertion depth into PCB plated through-holes, making it ideal for boards with limited back-side clearance. Tape-and-reel packaging supports automated pick-and-place assembly for consistent, high-throughput manufacturing of fine-pitch connector installations.

Frequently Asked Questions
What does the STL suffix indicate about TFM-143-22-STL-D-A-P-TR mounting characteristics?
STL designates a short tail length variant, meaning the connector pins extend less than the standard length below the PCB surface. This enables use in boards with limited back-side clearance, typically under 3 mm, while maintaining the 0.050-inch pitch 86-position dual-row configuration for dense signal routing.
For which high-channel-count applications is the TFM-143-22-STL-D-A-P-TR particularly well suited?
With 86 positions at 0.050-inch pitch, this connector suits FPGA daughter card interfaces requiring more than 80 signal pins, multi-channel DAQ modules, military backplane interconnects operating from -55°C to +125°C, and compact server blade edge connectors needing high pin density without increasing footprint area.
How does the 86-position TFM-143 compare to an 80-position variant for signal expansion headroom?
The TFM-143 provides 86 total positions (43 per row) versus 80 positions in a comparable variant, adding 6 extra pins at the same 0.050-inch pitch. This 7.5% increase in pin count allows routing additional power, ground, or control signals without requiring a larger footprint or switching to a different connector pitch.
