Frequently Asked Questions
How many positions does the SFM-124-L2-SM-D-A-K-TR have, and how are they arranged?
The SFM-124-L2-SM-D-A-K-TR features 48 positions arranged in a dual-row configuration with 0.050 inch (1.27 mm) pitch. Each row contains 24 pins, enabling compact high-density signal routing for board-to-board connections in space-constrained PCB designs requiring many signal paths.
What current and voltage ratings apply to the SFM-124-L2-SM-D-A-K-TR?
Each pin is rated at 1 A current with a voltage rating of 125 V AC/DC. The gold-plated phosphor bronze contacts with 30 µin finish provide contact resistance below 20 mΩ, supporting reliable signal transmission in high-cycle applications rated for 200 mating cycles minimum.
Which PCB assembly processes are compatible with the SFM-124-L2-SM-D-A-K-TR?
The surface mount design is compatible with standard reflow soldering processes at peak temperatures up to 260°C for 10 seconds per IPC/JEDEC J-STD-020. The TR suffix confirms tape-and-reel packaging for automated pick-and-place equipment, making it fully compatible with modern SMT production lines for high-volume assembly.
When would you choose SFM-124-L2-SM-D-A-K-TR over a through-hole socket strip?
The SFM-124-L2-SM-D-A-K-TR is preferred over through-hole alternatives when PCB real estate is limited, since surface mounting eliminates the need for 48 drilled holes and reduces board thickness. Its 0.050 inch pitch provides 40% higher pin density compared to 0.100 inch pitch alternatives, making it ideal for high-channel-count signal interfaces on multi-layer PCBs.
