Frequently Asked Questions
How many positions does the SFM-129-02-ZZ-D-A-K-TR have and how are they arranged?
The SFM-129-02-ZZ-D-A-K-TR has 58 total positions arranged in a dual-row configuration on a 0.050" (1.27 mm) pitch, giving 29 positions per row. This high-density layout keeps the connector footprint compact on surface-mount PCBs while providing a large number of signal and power contacts.
What current rating does each contact in the SFM-129-02-ZZ-D-A-K-TR support?
Each contact in the SFM-129-02-ZZ-D-A-K-TR is rated at 3 A, and the gold-plated Tiger Eye contact system provides reliable low-resistance mating. For designs that must pass high-current rails through the connector, multiple contacts can be paralleled to increase total current capacity.
Which automated assembly format does the SFM-129-02-ZZ-D-A-K-TR use, and how does this affect procurement?
The SFM-129-02-ZZ-D-A-K-TR is packaged in tape-and-reel (TR) format, which is compatible with standard surface-mount pick-and-place equipment. Tape-and-reel quantities typically require a minimum order of 250 to 1000 pieces depending on the distributor, but they reduce handling time and placement errors in high-volume production runs.
In what design scenarios is the SFM-129-02-ZZ-D-A-K-TR preferred over through-hole socket strips?
The SFM-129-02-ZZ-D-A-K-TR is preferred when the PCB design requires 0.050" pitch spacing and surface-mount soldering processes, saving the approximately 0.040" board thickness that through-hole pins would occupy. This makes it a better fit for slim mezzanine or daughter-card assemblies where board stacking height is constrained to under 5 mm.
