What are the key features of TST-105-03-G-D?

  • 10-position dual-row shrouded header with 0.100" (2.54 mm) pitch for reliable high-density board interconnection
  • Gold (10 µin) over nickel (50 µin) contact finish on phosphor bronze provides low contact resistance and excellent corrosion resistance
  • Shrouded design protects male contacts during mating and handling, reducing risk of bent pins in industrial environments
  • Compact 0.8" body length with 0.365" x 0.365" cross-section fits tight PCB layouts in embedded and instrumentation designs

What is TST-105-03-G-D used for?

The TST-105-03-G-D is ideal for board-to-board and cable-to-board interconnects in industrial control, test equipment, and embedded computing applications. The shrouded 10-pin dual-row configuration with gold contacts ensures reliable mating in environments subject to vibration or repeated connection cycles. It is widely used in development boards, instrumentation front-ends, and data acquisition modules requiring robust 0.100" pitch connectors.

Frequently Asked Questions

What contact finish does the TST-105-03-G-D use and why does it matter for signal integrity?

The TST-105-03-G-D uses gold (10 µin) over nickel (50 µin) on phosphor bronze contacts, providing low and stable contact resistance over thousands of mating cycles. This finish prevents oxidation that can increase contact resistance over time, ensuring reliable signal integrity in test and instrumentation applications where consistent low-resistance connections at 10 positions are critical.

How does the shrouded design of TST-105-03-G-D protect male contacts during assembly and field use?

The shrouded housing on the TST-105-03-G-D encloses the male contact pins within a 0.8" body, preventing accidental bending during PCB handling, automated assembly, and repeated field mating operations. This is particularly valuable in industrial and aerospace environments where boards may be inserted and removed frequently, protecting all 10 phosphor bronze pins from mechanical damage.

For a 10-signal interface on an embedded controller, how does the TST-105-03-G-D's dual-row layout compare to a single-row 10-pin header?

The TST-105-03-G-D arranges 10 positions in a dual-row configuration at 0.100" pitch, reducing the occupied PCB edge length by approximately 50% compared to a single-row 10-pin header. Its 0.8" body length and 0.365" depth make it a compact solution for embedded controller boards where PCB area is limited, while the shrouded housing prevents mis-mating of ribbon cables.

What procurement advantage does the TST-105-03-G-D offer for prototype and low-volume production runs?

The TST-105-03-G-D is available individually without minimum order requirements, making it cost-effective for prototype builds and low-volume production. Its standard 0.100" (2.54 mm) pitch is compatible with a broad ecosystem of mating connectors and ribbon cables, reducing sourcing complexity when engineers need to quickly validate a 10-position dual-row interface without committing to reel quantities.
