Frequently Asked Questions
What is the pin pitch and row configuration of TSM-128-03-STL-DH-A-K-TR?
TSM-128-03-STL-DH-A-K-TR uses a dual-row configuration with 2.54 mm (0.100 inch) pitch, providing 56 total positions. This standard pitch is compatible with a wide range of mating headers used in PCB stacking and backplane interconnect designs.
Which surface mount soldering processes are compatible with TSM-128-03-STL-DH-A-K-TR?
The connector supports standard reflow soldering processes. Its kinked tines maintain board contact during the reflow cycle, and the tape and reel (TR) packaging allows automated placement at typical SMT reflow temperatures up to 260°C per IPC/JEDEC J-STD-020 profiles.
When would a designer choose TSM-128-03-STL-DH-A-K-TR over a through-hole terminal strip?
A surface mount variant like TSM-128-03-STL-DH-A-K-TR saves board space and eliminates drilling costs, making it preferred for double-sided PCBs. The 56-position dual-row footprint achieves high pin density while keeping height profile low, typically under 8.5 mm above the board.
How does the gold contact plating on TSM-128-03-STL-DH-A-K-TR benefit signal integrity?
Gold plating provides a contact resistance below 20 milliohms, resists oxidation over a rated lifetime of at least 30 mating cycles, and maintains reliable low-noise connections for digital signals in industrial and test equipment applications operating at 3.3 V or 5 V logic levels.
