Key Features
- 30 micro-inch gold mating contact finish provides superior corrosion resistance and low contact resistance across thousands of mating cycles
- 0.050 inch (1.27 mm) pitch dual-row layout enables high-density signal routing within a compact SMT footprint
- High-reliability phosphor bronze contact material maintains consistent spring force over the full operating life
- Tape-and-reel (TR) packaging with -K option enables automated pick-and-place assembly in high-volume SMT production
Applications
The SFM-104-02-S-D-A-K-TR is used in high-density PCB interconnects for military, aerospace, and industrial electronics where long mating life and signal integrity are critical. Its surface-mount dual-row 8-position socket is ideal for daughter card attachment, memory module sockets, and test point headers in space-constrained designs. The gold contacts and phosphor bronze construction support demanding environments requiring reliable 0.050 inch pitch connectivity.

Frequently Asked Questions
What pitch and contact finish does SFM-104-02-S-D-A-K-TR use for mating connections?
The SFM-104-02-S-D-A-K-TR uses a 0.050 inch (1.27 mm) pitch with 30 micro-inch gold plating on its female mating contacts. The 30 micro-inch gold thickness ensures extremely low contact resistance below 20 milliohms and excellent durability across more than 100 mating cycles in high-reliability applications.
For which types of PCB assembly processes is SFM-104-02-S-D-A-K-TR optimized?
This connector is optimized for surface-mount reflow soldering processes, with the -TR suffix indicating tape-and-reel packaging for automated pick-and-place equipment. Standard 0402 and 0603 SMT lines can handle placement at typical reflow peak temperatures of 260 degrees C, supporting high-volume manufacturing.
How does the dual-row configuration of SFM-104-02-S-D-A-K-TR compare to single-row alternatives?
The dual-row design provides 8 positions in two parallel rows of 4, roughly halving the required PCB length compared to a single-row 8-position connector at the same 0.050 inch pitch. This allows routing 8 signals within a footprint approximately 0.2 inch long, critical in dense daughter card or module attachment scenarios.
What industries benefit most from the high-reliability rating of SFM-104-02-S-D-A-K-TR?
Military, aerospace, medical instrumentation, and industrial control applications benefit most from the high-reliability designation. These sectors require connectors rated for operating temperatures across at least -55 degrees C to +125 degrees C, vibration resistance, and stable 30 micro-inch gold contact performance over the product lifetime.
