Key Features
- 90-position dual-row SMT socket at 0.050" pitch for ultra-high-density interconnects
- Positive locking mechanism (K suffix) ensuring secure mating and vibration resistance
- Gold-plated contacts with 1A per pin rating for reliable signal and power distribution
- Wide operating temperature from -55°C to +125°C covering industrial and defense requirements
Applications
The SFM-145-T2-H-D-A-K is well-suited for demanding board-to-board applications in telecommunications infrastructure, industrial control equipment, and high-performance computing where 90 contacts at 0.050" pitch are required. The integrated locking retention (K option) makes it an excellent choice for vibration-prone environments such as robotics, automotive electronics, and aerospace systems where accidental unmating is unacceptable. Its surface mount form factor streamlines automated PCB assembly in high-volume production.

Frequently Asked Questions
What does the K suffix mean on SFM-145-T2-H-D-A-K and how does it affect assembly?
The K suffix indicates a locking retention feature that mechanically secures the mated connector pair, preventing accidental disconnection under vibration or shock loads. This is critical in applications like robotics and automotive electronics where the board assembly experiences mechanical stress, and it does not significantly impact the 0.050" pitch SMT assembly process.
How many positions does SFM-145-T2-H-D-A-K provide and what is the per-pin current rating?
The SFM-145-T2-H-D-A-K provides 90 positions in a dual-row layout at 0.050" (1.27mm) pitch. Each gold-plated contact is rated at 1A per pin, giving the connector a total capacity suitable for distributing both signals and moderate power across a dense 90-pin interconnect.
For a high-reliability aerospace design, does SFM-145-T2-H-D-A-K meet the thermal requirements?
Yes, the SFM-145-T2-H-D-A-K is rated for operating temperatures from -55°C to +125°C, which covers most aerospace and military standard thermal cycling requirements. The gold-plated contacts maintain low contact resistance across this range, supporting signal integrity throughout temperature excursions.
How does SFM-145-T2-H-D-A-K compare to SFM-142-L2-H-D-A for backplane designs requiring more pins?
The SFM-145-T2-H-D-A-K provides 90 positions versus 84 on the SFM-142-L2-H-D-A, offering 6 additional contacts per mating pair at the same 0.050" pitch and 1A per pin rating. The T2 tail option and built-in locking mechanism of the SFM-145-T2-H-D-A-K make it preferable when additional I/O pins and secure retention are both required in a backplane design.
