Frequently Asked Questions
How does the 0.050" pitch of SFM-146-L2-ZZ-D-A-K-TR compare to standard 0.100" pitch connectors in terms of board density?
At 0.050" (1.27 mm) pitch, the SFM-146-L2-ZZ-D-A-K-TR fits roughly twice as many pins per linear inch as 0.100" connectors. This means the 92-position dual-row strip occupies approximately the same board footprint as a 46-position 0.100" connector, making it ideal for high-density designs in aerospace avionics and compact embedded systems.
What is the per-pin current rating of SFM-146-L2-ZZ-D-A-K-TR, and how does it affect signal routing decisions?
Each pin on the SFM-146-L2-ZZ-D-A-K-TR carries up to 1A of current. Because this connector targets high-density signal applications rather than power distribution, designers should route power through dedicated power pins or separate connectors, using the 92 positions primarily for digital signals, control lines, and low-power analog signals.
Which high-reliability markets use the SFM-146-L2-ZZ-D-A-K-TR?
This connector's -55°C to +125°C operating range, gold-plated contacts, and surface mount high-reliability construction make it a common choice in military electronics, avionics line-replaceable units, satellite subsystems, and ruggedized industrial controllers. The 92-position count suits complex FPGA or processor mezzanine cards where many simultaneous signal paths are required.
Does the tape-and-reel (TR) packaging of SFM-146-L2-ZZ-D-A-K-TR support automated SMT assembly?
Yes. The TR suffix confirms the SFM-146-L2-ZZ-D-A-K-TR ships in tape-and-reel format, fully compatible with standard pick-and-place equipment. This enables automated SMT placement of all 92 positions in a single pass, reducing handling errors and supporting high-volume production lines that require consistent placement accuracy within ±0.05 mm.
