Frequently Asked Questions
How many positions and what pitch does the TST-110-03-H-D provide for PCB header connections?
The TST-110-03-H-D provides 20 positions arranged in a dual-row configuration on a 0.100 inch (2.54 mm) pitch, making it compatible with standard ribbon cables and mating sockets. The shrouded rectangular housing measures 1.3 inch body length to support compact PCB layouts.
What contact finish is used on TST-110-03-H-D and why does it matter for signal reliability?
The connector uses 30 microinch gold over nickel for both mating and termination contact finishes, providing excellent corrosion resistance and low, stable contact resistance over thousands of mating cycles. This gold finish is particularly valuable in test fixtures and instrumentation with frequent connect and disconnect operations.
Which design scenarios benefit most from selecting the shrouded TST-110-03-H-D over an unshrouded header?
The shrouded design of TST-110-03-H-D prevents mis-mating by physically guiding the mating connector into the correct 20-pin, 0.100 inch pitch position, which is critical in industrial automation, embedded systems, and field-replaceable module designs where incorrect connections could damage hardware.
