What are the key features of TST-110-03-F-D?
- 20-position dual-row shrouded header at 0.100" (2.54 mm) pitch with phosphor bronze contacts providing spring-force retention and reliable mating across repeated insertion cycles
- Gold flash over nickel mating contact finish ensuring low contact resistance and corrosion protection for reliable signal integrity in humid and industrial environments
- Integrated polarizing shroud with 1.3" body length and keyed housing preventing mis-mating of 20-pin ribbon cables and protecting all male contacts from mechanical damage
What is TST-110-03-F-D used for?
The TST-110-03-F-D is used in industrial control systems, embedded computing platforms, and test and measurement equipment requiring reliable 20-pin board-to-cable connectivity with polarity protection. Its dual-row 0.100" pitch configuration accommodates data buses, power rails, and ground pins in a 1.3" length shrouded housing that mates directly with standard 20-pin IDC ribbon cable connectors. The phosphor bronze contacts with gold flash finish ensure consistent contact resistance in environments with temperature cycling and vibration.

Frequently Asked Questions
What contact material and finish does the TST-110-03-F-D use, and how does that affect its service life?
The TST-110-03-F-D uses phosphor bronze contacts with a gold flash over nickel mating finish and a tin-over-nickel barrier termination finish. Phosphor bronze provides excellent spring elasticity maintaining consistent contact force over thousands of mating cycles. The gold flash mating surface resists oxidation and corrosion, keeping contact resistance below 20 milliohms through the full industrial operating temperature range, while the nickel barrier prevents tin migration to the mating zone during soldering.
What is the body length and position layout of the TST-110-03-F-D, and how does it fit standard ribbon cable assemblies?
The TST-110-03-F-D has a 1.3" (33 mm) body length with 20 positions arranged in 2 rows at 0.100" (2.54 mm) pitch, providing 10 contacts per row. This geometry is dimensionally compatible with standard 20-pin IDC (insulation displacement connector) ribbon cable assemblies using 1.27 mm wide flat cables. The shroud height and key position align with industry-standard ribbon cable housings, allowing direct mating without custom cable tooling.
In which industrial scenarios is a 20-pin shrouded header preferred over an unshrouded dual-row header?
A 20-pin shrouded header like the TST-110-03-F-D is preferred in industrial and field-service scenarios where cables may be disconnected and reconnected by technicians without detailed wiring diagrams. The shroud prevents inserting a 20-pin cable offset by 2 positions, which at 5 V logic levels could connect power to unprotected signal inputs and damage circuitry. Shrouded headers are also preferred in vibration environments where the housing provides additional cable retention force beyond solder joint strength alone, such as in motor control cabinets and mobile equipment.
