Samtec, Inc. offers highly configurable micro pitch terminal strips with immediate availability in production quantities. Designers can choose from a variety of sizes, pin configurations, plating and processing options, leading to unrivaled design flexibility. Part of the Samtec Reserve program, FTSH products are available for next-day volume delivery and are also part of Samtec’s free sample program. They are in stock at most Samtec-authorized distributors.
The FTSH series is a 1.27 mm centerline terminal strip (“header”) available in both surface-mount (SMT) and through-hole designs, and in both vertical and right-angle configurations. These high-reliability connectors are available in 2 to 50 pins per row, with selective gold/tin plating in flash or light gold. Options to improve manufacturability include shrouds, locking clips, guideposts, pick-and-place pads, ejector and keying shrouds for mating with cable assemblies, and tape-and-reel packaging.

Samtec FTSH terminal strips are commonly used as JTAG connectors. The Joint Test Action Group (JTAG) is the common name for IEEE Standard 1149.1. This standard defines a specific method for testing board-level interconnects, known as Boundary Scan. In short, JTAG was created to test for common problems, but lately it has become a way to configure devices.
Common sizes are 10-pin (2 x 5), 14-pin (2 x 7), and 20-pin (2 x 10). JTAG connectors can be either through-hole or SMT, and either shrouded or unshrouded. The FFSD series is a popular low-profile ribbon cable assembly that mates with the FTSH series.
FTSH terminal strips are Samtec Severe Environment Tested qualified, RoHS compliant, and are a Samtec Extended Life Product (E.L.P.). They meet or exceed MIL-DTL-55302 testing, are available as Samtec Automotive A-Series and are lead-free solderable.
