Frequently Asked Questions
What does the STL suffix mean in the TSM-123-03-STL-DH-A-K-TR part number?
STL designates a straddle mount configuration, allowing the connector to mount on the edge of a PCB. This positions the 46-pin dual-row connector to straddle the board edge at 0.100" (2.54 mm) pitch, enabling direct board-to-board or board-to-cable mating without additional standoffs or housings.
What current rating does each pin support on the TSM-123-03-STL-DH-A-K-TR?
Each of the 46 pins on the TSM-123-03-STL-DH-A-K-TR is rated at 3A. Combined with gold-plated contacts and an operating temperature range of -55°C to +125°C, the connector reliably handles both signal-level and light power distribution in demanding environments.
Which PCB assembly scenarios suit the TSM-123-03-STL-DH-A-K-TR straddle-mount design?
Straddle-mount connectors like the TSM-123-03-STL-DH-A-K-TR are commonly used in modular industrial controls, test and measurement breakout boards, and edge-card interfaces for embedded systems. The 0.100" pitch and 46-position count allow dense signal routing along the PCB edge, saving internal board area compared to top-mount alternatives.
Can the TSM-123-03-STL-DH-A-K-TR be used in high-cycle mating applications such as development kits?
Yes. Gold-plated contacts on the TSM-123-03-STL-DH-A-K-TR deliver low and stable contact resistance through many insertion cycles, making the connector well suited for development boards, lab fixtures, and field-service modules where the 46 pins may be mated and unmated hundreds of times over the product lifespan.
