Key Features
- 90-position dual-row SMT socket strip on 0.050" (1.27 mm) pitch for high-density board-to-board mating
- Gold-over-nickel contact finish delivering reliable low-resistance connections rated at 1 A per contact
- High-reliability friction-lock design operating across -55°C to +125°C for demanding industrial environments
Applications
The SFM-145-T2-STL-D-A-K is well suited for high-density mezzanine and board-stacking applications in telecommunications equipment, industrial control cards, and test and measurement platforms. Its 90 dual-row contacts at 0.050" pitch provide a compact yet high-pin-count interface ideal for FPGA daughter cards, memory modules, and backplane interconnects that demand reliable signal integrity across a wide temperature range.

Frequently Asked Questions
How many contacts does the SFM-145-T2-STL-D-A-K provide, and what is their current rating?
The SFM-145-T2-STL-D-A-K provides 90 contacts arranged in a dual-row configuration, each rated at 1 A continuous current. The gold-over-nickel finish ensures low contact resistance suitable for both signal and low-level power distribution in compact PCB assemblies.
Over what temperature range can the SFM-145-T2-STL-D-A-K operate reliably in an industrial control chassis?
This socket strip is specified for operation from -55°C to +125°C, making it suitable for industrial control, automotive test fixtures, and harsh-environment embedded systems. The SMT mounting and friction-lock retention maintain mechanical integrity across the full 180°C thermal span without derating.
What pitch does the SFM-145-T2-STL-D-A-K use, and how does it compare to 0.100" alternatives for board space savings?
The connector uses a 0.050" (1.27 mm) pitch, which is half that of standard 0.100" (2.54 mm) headers. At 90 positions in a dual-row layout, this allows a contact field roughly half the PCB footprint length of an equivalent 0.100" strip, enabling denser board stacking in space-constrained designs such as FPGA mezzanine cards or compact embedded computing modules.
