Frequently Asked Questions
How many positions and rows does the SFM-109-T2-L-D-A-K-TR provide, and what is its pitch?
The SFM-109-T2-L-D-A-K-TR is an 18-position dual-row connector with 0.050" (1.27 mm) pitch, placing 9 contacts per row. The resulting mated length is approximately 11.43 mm, making it a compact choice for high-density signal routing on boards with tight spacing constraints.
For what manufacturing environments is the tape-and-reel packaging of the SFM-109-T2-L-D-A-K-TR intended?
The -TR suffix indicates tape-and-reel packaging, designed for use with automated SMT pick-and-place machines in high-volume PCB production environments. Reels typically hold 250 to 1000 units and ensure consistent part orientation during placement, reducing misalignment errors across all 18 contact positions in each reflow cycle.
How does the SFM-109-T2-L-D-A-K-TR compare to a single-row connector of the same contact count?
A dual-row 18-position connector at 0.050" pitch requires only 9 contact positions along each row edge, cutting the required connector length roughly in half compared to a single-row 18-position alternative at the same pitch. This dual-row arrangement reduces PCB edge consumption from approximately 22.86 mm to 11.43 mm, a critical advantage in compact module designs.
What is the contact plating on the SFM-109-T2-L-D-A-K-TR, and why does it matter for reliability?
SAMTEC SFM series connectors use gold-plated contacts, which provide corrosion resistance, stable contact resistance below 20 mΩ, and a rated service life of 500 or more mating cycles depending on the specific variant. Gold plating is especially important in low-signal-level applications where even slight contact oxidation could degrade signal integrity or increase resistance beyond acceptable limits.
