Key Features
- 78-position dual-row configuration with 0.050" (1.27 mm) pitch for high-density SMT board connections
- Gold-plated contacts rated at 1 A continuous current for reliable low-resistance interconnects
- High-reliability construction rated from -55°C to +125°C suitable for harsh industrial environments
Applications
The SFM-139-02-H-D-A is well suited for high-density board-to-board and mezzanine interconnect applications in telecommunications, industrial control systems, and test equipment. Its 0.050" pitch dual-row layout enables compact PCB footprints where 78 signal connections are required in minimal board real estate. Engineers designing ruggedized systems benefit from the extended -55°C to +125°C operating range and gold-contact reliability.

Frequently Asked Questions
How many positions and rows does the SFM-139-02-H-D-A provide, and what is its pin pitch?
The SFM-139-02-H-D-A features 78 positions arranged in 2 rows with a 0.050" (1.27 mm) pitch. This dual-row, fine-pitch layout delivers high contact density for compact SMT board-to-board applications requiring many signal connections in limited board space.
What current rating and temperature range should designers expect for the SFM-139-02-H-D-A in industrial applications?
Each contact in the SFM-139-02-H-D-A is rated at 1 A continuous current, and the connector operates reliably across a temperature range of -55°C to +125°C. This makes it a strong candidate for industrial, telecom, and defense electronics where wide thermal cycling is common.
How does the SFM-139-02-H-D-A compare to a standard 0.100" pitch connector for the same number of positions?
At 0.050" pitch, the SFM-139-02-H-D-A occupies roughly half the board length of an equivalent 0.100" pitch connector carrying the same 78 pins. This 50% footprint reduction is critical in space-constrained PCB layouts such as mezzanine cards, backplanes, and compact test instruments requiring high pin counts.
