Frequently Asked Questions
What makes SFM-149-L2-FM-D-A-K-TR suited for FPGA or processor daughterboard connections?
With 98 positions at 1.27 mm pitch in a dual-row SMT format, this connector carries wide parallel buses spanning 32-bit or 64-bit data paths plus address and control lines in a single connector measuring approximately 63 mm long. Each contact handles 1 A, supporting mixed signal and power delivery simultaneously.
How does the key and retention option in SFM-149-L2-FM-D-A-K-TR prevent mating errors?
The polarization key (K suffix) provides mechanical orientation guidance so boards can only mate in one direction, eliminating reversed insertion errors on 98-pin assemblies. The retention mechanism applies a hold-down force that resists accidental separation under vibration loads common in industrial equipment operating at up to 10 G shock.
At what operating temperature range does SFM-149-L2-FM-D-A-K-TR remain reliable?
The SFM-149-L2-FM-D-A-K-TR is rated for operation across -55 °C to +125 °C, covering both harsh cold storage environments and elevated PCB temperatures typical of densely packed server or power electronics boards. Contact resistance remains below 20 milliohms throughout this temperature range.
