What are the key features of SFM-148-T2-FM-D-A-K-TR?
- 96-position dual-row layout at 0.050" (1.27 mm) pitch provides maximum signal density in a compact SMT footprint
- High-reliability stamped contacts rated 1.0 A per contact at 125°C for demanding industrial and communications applications
- T2 tail length and FM float-mount option accommodate PCB tolerances of ±0.25 mm for improved assembly yield
What is SFM-148-T2-FM-D-A-K-TR used for?
The SFM-148-T2-FM-D-A-K-TR is optimized for high-density mezzanine board stacking and FPGA daughter-card interfaces where 96 signal lines must be routed within a minimal PCB area. Its float-mount feature compensates for PCB-to-PCB misalignment of up to ±0.25 mm, reducing mechanical stress during mating in automated assembly. This connector is widely used in communications infrastructure, server backplanes, and industrial computing platforms requiring reliable, repeatable high-pin-count interconnects.

Frequently Asked Questions
How does the float-mount (FM) feature of the SFM-148-T2-FM-D-A-K-TR improve assembly reliability?
The float-mount option allows lateral movement of ±0.25 mm during PCB-to-PCB mating to absorb misalignment from manufacturing tolerances. This reduces mechanical stress on solder joints across all 96 positions, lowering the risk of pad lifting or cold joints. It is particularly valuable in automated assembly lines where fixture alignment repeatability is limited to ±0.1 mm.
What contact current rating and temperature range does the SFM-148-T2-FM-D-A-K-TR support for industrial use?
Each contact in the SFM-148-T2-FM-D-A-K-TR is rated for 1.0 A continuous current, and the connector operates reliably from -55°C to +125°C. With 96 contacts in a dual-row 1.27 mm pitch layout, the device can carry up to 48 A total signal current, suitable for mixed signal and low-power distribution in industrial computing and communications hardware.
For a high-density FPGA mezzanine design, how does the SFM-148-T2-FM-D-A-K-TR compare to 2.54 mm pitch alternatives?
The 0.050" (1.27 mm) pitch of the SFM-148-T2-FM-D-A-K-TR enables routing 96 signals in roughly half the board area required by equivalent 2.54 mm pitch connectors. For a typical FPGA I/O expansion card, this can reduce connector footprint from approximately 120 mm x 10 mm to about 62 mm x 5 mm, freeing significant PCB real estate for decoupling capacitors and routing channels.
When should designers choose the SFM-148-T2-FM-D-A-K-TR over a press-fit connector with the same pin count?
SMT connectors like the SFM-148-T2-FM-D-A-K-TR are preferred when PCB thickness is less than 1.6 mm or when both sides of the board must remain obstruction-free. Press-fit requires a minimum 1.6 mm board thickness and dedicated tooling for insertion forces up to 100 N for 96-pin connectors, whereas reflow soldering integrates seamlessly into standard SMT assembly lines without additional process steps.
