Key Features
- Tiger Eye contact design provides superior vibration resistance and maintains reliable connection through 200+ mating cycles
- Dual-row 40-position layout with tin-over-nickel (Sn/Ni) contact finish for long-term corrosion resistance
- LC (low-profile) SMD termination enables minimal component height in space-constrained PCB assemblies
- Female socket body style with precision-molded housing for accurate 0.100 inch pitch mating alignment
Applications
SFM-120-01-S-D-LC is used for board-to-board stacking connections in FPGA development boards, memory module interfaces, and high-density backplane assemblies requiring reliable 40-position dual-row connectivity. Its Tiger Eye contact technology and SMD termination make it well suited for high-cycle laboratory instrumentation, test fixtures, and industrial control modules where signal integrity across 200 or more mating cycles is required.

Frequently Asked Questions
What contact finish does the SFM-120-01-S-D-LC use and why does it matter for reliability?
SFM-120-01-S-D-LC uses a tin (Sn) finish with a nickel (Ni) barrier on the termination contacts. The Ni barrier prevents tin migration and maintains contact resistance below 20 mΩ across the 200+ mating cycles expected in test and instrumentation applications.
How many positions and rows does the SFM-120-01-S-D-LC connector provide?
SFM-120-01-S-D-LC provides 40 positions arranged in a dual-row female socket configuration on 0.100 inch (2.54 mm) pitch, offering 20 contacts per row for high-density board-to-board signal routing in FPGA and backplane designs.
What advantage does the Tiger Eye contact feature give SFM-120-01-S-D-LC in vibration-prone environments?
Tiger Eye contacts use a bifurcated spring design that maintains at least 2 contact points per pin, keeping contact resistance stable below 20 mΩ under vibration loads up to 20g, making SFM-120-01-S-D-LC suitable for industrial and aerospace test environments.
For which FPGA or development board form factors is SFM-120-01-S-D-LC a compatible mating socket?
SFM-120-01-S-D-LC mates with SAMTEC TSM or SSM series 40-position dual-row headers on 0.100 inch pitch. This makes it compatible with Xilinx Spartan evaluation boards, Arduino Mega shields, and custom FPGA carrier boards using 40-pin expansion headers.
