What are the key features of TFM-144-22-S-D-A-P-TR?
- 44-position dual-row layout at 0.050 inch (1.27 mm) pitch delivers high signal density in a compact SMD footprint
- Tiger Eye contact system ensures low, stable contact resistance and reliable mating performance across hundreds of connection cycles
- Tape-and-reel (-TR) packaging with SMD termination enables fully automated pick-and-place and reflow soldering in production environments
What is TFM-144-22-S-D-A-P-TR used for?
The TFM-144-22-S-D-A-P-TR is designed for high-density board-to-board interconnect applications in FPGA carrier boards, server mezzanine modules, and data acquisition systems where maximizing signal count per unit area is essential. Its 44-position dual-row configuration routes up to 88 signals across a 1.27 mm pitch footprint, supporting parallel bus interfaces and high-speed differential pairs in compact electronic assemblies. The SMD form factor also suits multi-layer PCB designs where preserving inner routing layers beneath the connector is a priority.

Frequently Asked Questions
How many signal contacts does TFM-144-22-S-D-A-P-TR provide and at what pitch?
The TFM-144-22-S-D-A-P-TR provides 44 positions per row in a dual-row arrangement, delivering 88 total contacts on a 0.050 inch (1.27 mm) pitch. This high signal density allows engineers to route parallel buses or multiple differential pairs through a single compact connector without expanding board area significantly.
How does the Tiger Eye contact design in TFM-144-22-S-D-A-P-TR improve connection reliability?
SAMTEC's Tiger Eye contacts feature a dual-beam design that applies consistent normal force on mating pins, keeping contact resistance stable — typically below 20 mΩ — even after repeated insertion and extraction cycles. This reliability is critical in systems such as test and measurement equipment or field-replaceable mezzanine cards that require hundreds of mating cycles without signal degradation.
What assembly process is recommended for soldering the TFM-144-22-S-D-A-P-TR to a PCB?
The surface-mount termination and -TR tape-and-reel packaging make the TFM-144-22-S-D-A-P-TR designed for automated reflow soldering. SAMTEC TFM series connectors are rated for peak reflow temperatures up to 260°C, compatible with standard SAC305 lead-free solder profiles used in modern SMT production lines handling 88-pin connectors in single-pass reflow ovens.
When is TFM-144-22-S-D-A-P-TR a better choice than a 0.100 inch pitch alternative for the same signal count?
At 0.050 inch pitch, the TFM-144-22-S-D-A-P-TR occupies roughly half the board length of a 0.100 inch pitch connector carrying 88 signals. For a PCB where connector length must stay under 30 mm and signal count reaches 88 pins, the 1.27 mm pitch TFM variant fits within this constraint while the 2.54 mm pitch alternative would require nearly 60 mm, making the TFM the clear choice for space-critical designs.
