Frequently Asked Questions
What contact finish and pitch does the TST-109-03-F-D use to ensure reliable signal connections?
The TST-109-03-F-D uses gold flash over nickel on its 18 mating contacts at 0.100 inch (2.54 mm) pitch. Gold-flash plating provides low contact resistance and corrosion resistance for reliable signal integrity over many mating cycles, making this connector suitable for industrial and embedded control applications.
How does the shrouded housing on TST-109-03-F-D reduce field wiring errors?
The shrouded housing of the TST-109-03-F-D physically surrounds all 18 pins at 0.100 inch pitch and guides the mating cable connector into a single correct orientation, preventing inverted or offset insertion errors. This is especially valuable in field-assembled industrial wiring harnesses where technicians may insert connectors under poor lighting or time constraints.
Which cable connector types mate with the TST-109-03-F-D in standard prototyping setups?
The TST-109-03-F-D with its 18-position dual-row male square-pin layout at 0.100 inch (2.54 mm) pitch mates with standard IDC ribbon cable connectors, discrete female crimp housings, and 2.54 mm pitch jumper wires commonly used in development kits, microcontroller evaluation boards, and rapid prototyping setups.
What are the physical dimensions of the TST-109-03-F-D body relevant to PCB layout planning?
The TST-109-03-F-D has a body length of 1.2 inch, breadth of 0.365 inch, and depth of 0.365 inch. These dimensions, combined with the 18-position dual-row 0.100 inch pitch layout, allow designers to accurately reserve PCB footprint area and maintain clearance requirements in high-density board layouts for industrial and embedded computing systems.
