What are the key features of TST-108-04-H-D?
- 16-position dual-row layout on 0.100" (2.54 mm) pitch provides 16 polarized signal contacts in the industry-standard 2.54 mm grid
- Tall H shroud height fully encloses the contact pins, preventing mis-mating and protecting contacts from physical damage during handling
- Through-hole termination delivers robust solder joint mechanical strength for board-to-wire harness connections in vibration environments
What is TST-108-04-H-D used for?
The TST-108-04-H-D is commonly used as a polarized board-to-wire header in industrial control panels, embedded computing boards, and test harnesses where 16 signals must be routed reliably from PCB to cable assemblies. Its tall shroud and 2.54 mm pitch accept standard IDC ribbon cable connectors and discrete wire housings across a wide range of automation, robotics, and instrumentation applications.

Frequently Asked Questions
What shroud height does the H option provide on the TST-108-04-H-D and why does it matter for cable connector retention?
The H (high) shroud on the TST-108-04-H-D stands approximately 8.5 mm above the PCB surface, fully enclosing all 16 dual-row pins. This extended shroud depth increases the mating connector's guided engagement length by 3 mm compared to the standard shroud, reducing the risk of connector misalignment and accidental disengagement in vibrating or cable-tension environments.
How does the TST-108-04-H-D's 0.100" pitch constrain cable assembly options compared to finer-pitch shrouded headers?
The 0.100" (2.54 mm) pitch of the TST-108-04-H-D accepts standard 16-pin IDC ribbon cable connectors, discrete 2.54 mm crimp housings, and off-the-shelf jumper cables without custom tooling. Finer 0.050" pitch alternatives require specialized crimping tools and smaller-gauge wire, increasing harness assembly cost, so the 2.54 mm pitch is preferred for low-cost internal wiring in industrial and consumer electronics.
What current rating per contact applies to the TST-108-04-H-D when used to distribute both power and signal on the same connector?
SAMTEC TST series headers are rated at 3 A per contact at 25°C for through-hole 2.54 mm pitch variants, allowing the TST-108-04-H-D to carry up to 48 W of combined power across dedicated power pins on a 16 V rail while simultaneously routing signal lines at logic levels. Designers should derate to 2 A per contact above 70°C ambient to avoid thermal degradation of the plastic housing.
