What are the key features of SFM-145-02-ZZ-D-A-K-TR?
- 90-position dual-row SMD socket strip on 0.050-inch (1.27mm) pitch enabling high-density board-to-board interconnect in compact assemblies
- High-reliability construction with gold-plated contacts rated for 200+ mating cycles and low contact resistance under 20mΩ
- Tape-and-reel (TR) packaging for automated pick-and-place assembly, reducing handling time at volumes above 500 units
What is SFM-145-02-ZZ-D-A-K-TR used for?
The SFM-145-02-ZZ-D-A-K-TR is designed for high-density board-to-board connections in embedded computing, FPGA mezzanine cards, and test-and-measurement daughter card applications where 90 signals must pass through a 0.050-inch pitch interface. Its dual-row SMD footprint allows integration into assemblies with height budgets under 5mm, making it suitable for ruggedized military and aerospace backplane systems. It is also used in medical imaging and communication infrastructure boards where reliable signal integrity across 90 positions is critical.

Frequently Asked Questions
How many positions and rows does SFM-145-02-ZZ-D-A-K-TR provide, and what pitch does it use?
The SFM-145-02-ZZ-D-A-K-TR is a 90-position dual-row socket strip arranged as 2 rows of 45 contacts on a 0.050-inch (1.27mm) pitch. This fine pitch enables signal routing density that is approximately double that of standard 0.100-inch pitch connectors, making it ideal for FPGA daughter cards and compact embedded computing modules.
Which mating connector series is compatible with SFM-145-02-ZZ-D-A-K-TR for board-to-board stacking?
The SFM-145-02-ZZ-D-A-K-TR mates with SAMTEC TSM and TFM series headers also on 0.050-inch pitch, supporting board-to-board stack heights from 4mm to 20mm depending on the mating header selected. The 90-position count allows routing up to 88 signal lines plus 2 power or ground connections in a single dual-row connector, reducing the number of connectors needed per PCB.
What assembly advantages does the tape-and-reel packaging of SFM-145-02-ZZ-D-A-K-TR provide?
The TR (tape-and-reel) packaging enables automated SMD pick-and-place placement at line speeds typical of 0402 or 0603 passive components, saving 3 to 5 seconds per connector compared to manual hand-placement at production volumes above 500 units per day. The reel format also reduces ESD exposure risk compared to bulk packaging, important for gold-plated 90-position connectors.
For which high-reliability applications is SFM-145-02-ZZ-D-A-K-TR most appropriate?
The SFM-145-02-ZZ-D-A-K-TR is rated for over 200 mating cycles and features gold-plated contacts with contact resistance under 20mΩ, making it appropriate for military avionics, aerospace payload modules, and ruggedized industrial computing where repeated board swaps occur over a 10-year to 15-year product lifecycle. Its SMD construction also withstands shock and vibration environments typical of MIL-STD-810G testing requirements.
