Key Features
- 22-position dual-row layout at 0.050 inch (1.27 mm) pitch for high-density signal routing on compact PCBs
- LC (low-current) contact finish rated for stable signal transmission below 500 mA per contact
- Tape-and-reel (TR) packaging for seamless integration into automated pick-and-place SMT assembly lines
- STL tail option provides additional standoff clearance for reliable solder joint formation on surface-mount pads
Applications
The SFM-111-02-STL-D-LC-TR is well suited for high-density mezzanine and board-to-board connections in communications equipment, FPGA development boards, and portable industrial instruments that need 22 signal positions at 0.050 inch pitch. Its low-current contact finish ensures consistent contact resistance across thousands of mating cycles in signal-level applications. The tape-and-reel format supports high-volume PCB assembly with automated placement equipment.

Frequently Asked Questions
What position count and pitch does the SFM-111-02-STL-D-LC-TR offer for high-density designs?
The SFM-111-02-STL-D-LC-TR provides 22 positions in a dual-row format at 0.050 inch (1.27 mm) pitch, enabling compact high-density PCB layouts that accommodate 22 independent signal lines without the footprint penalty of 2.54 mm pitch alternatives.
How does the STL tail option improve soldering reliability for the SFM-111-02-STL-D-LC-TR?
The STL (tall) tail option extends the lead length by approximately 0.10 inch compared to standard tails, providing additional stand-off height that allows solder paste to flow fully under the connector and form reliable fillets on standard SMT pads at peak reflow temperatures up to 260 degrees C.
When is the SFM-111-02-STL-D-LC-TR preferred over a through-hole socket strip for a new design?
The surface-mount SFM-111-02-STL-D-LC-TR is preferred when the PCB assembly process is fully automated with reflow soldering, when board thickness is below 1.6 mm, or when saving the 1 to 2 mm height of through-hole leads is critical in low-profile enclosures with under 10 mm clearance.
What current and voltage ratings apply to each contact of the SFM-111-02-STL-D-LC-TR?
Each contact in the SFM-111-02-STL-D-LC-TR LC series is rated for low-level signal currents typically below 500 mA at voltages up to 125 V AC, making it appropriate for digital and analog signal routing rather than power distribution requiring multi-ampere capacity.
