Frequently Asked Questions
What is the pitch and row configuration of the TSM-115-03-STL-DH-A-K-TR?
The TSM-115-03-STL-DH-A-K-TR features a 0.100-inch (2.54 mm) pitch with a dual-row layout totaling 30 positions (15 pins per row), making it suitable for dense surface mount board interconnect applications requiring a compact footprint.
Which PCB assembly processes are compatible with the TSM-115-03-STL-DH-A-K-TR surface mount termination?
This connector uses surface mount termination and is compatible with standard reflow soldering processes at temperatures up to 260 °C, per JEDEC J-STD-020 guidelines. Its tape-and-reel (TR) packaging supports automated pick-and-place machines in high-volume SMT production lines.
What current rating does the TSM-115-03-STL-DH-A-K-TR support per contact?
Each contact of the TSM-115-03-STL-DH-A-K-TR is rated at 1 A, with a voltage rating of 125 V AC/DC. This makes the connector appropriate for low-power signal lines in industrial control, embedded computing, and telecommunications backplane applications requiring 30 discrete connections.
How does the gold plating on the TSM-115-03-STL-DH-A-K-TR contacts benefit long-term connector performance?
Gold plating on the contacts provides a contact resistance below 20 mΩ and offers excellent corrosion resistance, ensuring stable signal integrity over thousands of mating cycles. This is especially valuable in harsh environments or test and measurement equipment where consistent electrical performance is critical across the full operating temperature range of -55 °C to +125 °C.
When would TSM-115-03-STL-DH-A-K-TR be preferred over a through-hole terminal strip in a compact design?
The SMT form factor of the TSM-115-03-STL-DH-A-K-TR eliminates the need for drilled through-holes, saving PCB space and reducing board thickness, which is critical in designs with a board area budget under 50 mm². It also enables placement on both sides of the PCB, increasing routing flexibility in high-density applications such as medical devices and industrial sensor modules.
