Frequently Asked Questions
What is the pin count and pitch of the SFM-123-02-S-D-A-K-TR?
The SFM-123-02-S-D-A-K-TR has 46 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch, making it suitable for high-density SMT board-to-board connections requiring compact layouts.
How much current can each contact in the SFM-123-02-S-D-A-K-TR carry?
Each contact in the SFM-123-02-S-D-A-K-TR is rated for approximately 1 A per pin, with gold-plated finish ensuring low contact resistance across the 46 positions to maintain signal integrity in high-density assemblies.
In which system-level applications is the SFM-123-02-S-D-A-K-TR commonly used?
This connector is widely used in mezzanine board-to-board stacking, backplane daughter-card interfaces, and high-reliability instrumentation systems where 46 positions at 0.050" pitch provide the necessary signal density within a compact SMT footprint.
When would a designer choose the dual-row SFM series over a single-row alternative?
A dual-row SFM connector like this part provides up to 46 signals in a footprint roughly half the length of a single-row alternative at the same 0.050" pitch, making it preferable whenever board real estate is limited and high signal count is required.
