Super-size. Add-on. Extra. More.
We see terms like these a lot, whether at the drive through or shopping online. There’s always something else you can add to your order or put in your cart – and usually at an additional cost. Fairly certain at this point most of us know “guac is extra,” right?!

Unlike guacamole, Samtec’s SI Lite products provide the board stacker solution you need at the right price, along with a few bonuses that aren’t “extra.” These cost-effective products are rated up to 8 Gbps with rugged options and additional testing to help you run high-speed signals in a variety of applications.
From standard to modified, SI Lite products offer a wide range of design flexibility including choice of pitch, pin count, stack height, orientation, and plating, plus rugged options such as screw downs and latches. Additionally, these solutions are compatible with many popular industry standards: PCIe® 1.0, 2.0 and 3.0, JTAG, LVDS, and others.


Samtec offers standard test procedures that push the industry limits to ensure quality and durability in any application, which apply to several SI Lite products at no additional cost. E.L.P™ products are tested to rigorous standards, which evaluate contact resistance in simulated storage and field conditions: 10 year MFG and high-mating cycles from 250 to 2,500.

Taking that a step further, Severe Environment Testing (SET) ensures specific products are more than suitable for military, space, automotive, industrial, and other extreme applications. This includes higher mating cycles, intense shock/vibration, temperature cycling, DWV at high altitude, non-operating class temperature, electrostatic discharge, and outgassing. Available test reports can be found at the links below.
