FW-SM
Flexible Micro Board Stacking Header, 0.050" Pitch
The FW-SM series is a surface-mount PCB header system that allows designers to create part numbers for specific, non-standard board stacking heights. Our manufacturing process allows us to locate the body on the terminal pin in increments of .005” (0.13 mm).
Features
Cost saving flash gold plating available
End shroud option available
Flexible stack heights
Guide post option available
Optional tape and reel packaging
Surface mount tails

How is this calculated?
Protocol capability of Samtec connectors results from a comparison of the protocol channel data rate and the Samtec Channel Performance Metric (CPM) per product. The Samtec CPM estimates connector performance in a pre-defined channel as illustrated below.
This channel-based approach factors impairments—such as the crosstalk and reflections—inherent in real-world signal channels. Samtec CPM sums all channel noise sources and then determines the resultant signal to noise ratio in a specific mated connector pair. By its very nature, CPM is a function of channel assumptions made and will vary from application to application. Achieving similar results requires good SI design practice in the system PCB(s) and using Samtec-provided connector breakout regions (BOR).
The FW-SM series has a CPM of 8 Gbps NRZ.
FW-SM products are capable of protocols whose channel data rates are less than this CPM.
For more information, please read this blog article: A New High Speed Connector Rating That Accounts For The Entire System and download the Samtec Channel Performance Metric white paper.
