Key Features
- 4-position dual-row 0.100-inch pitch SMT terminal strip with dual-voltage (DV) option for multi-voltage signal routing
- Polarization key (P) prevents incorrect mating orientation, reducing assembly errors in production environments
- Surface-mount (SM) termination with long-tail (STL) option for improved solder wetting and mechanical retention
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for high-volume manufacturing
Applications
TSM-102-05-STL-DV-P-TR is suited for compact PCB interconnects in consumer electronics, industrial sensors, and embedded control modules where a 4-position dual-row 0.100-inch pitch surface-mount header is needed. Its dual-voltage capability supports mixed-logic boards carrying both 3.3 V and 5 V signals on the same connector body. The polarization key ensures correct plug orientation in field-maintenance scenarios where connectors may be removed and reinserted frequently.

Frequently Asked Questions
What does the STL (long-tail) option on TSM-102-05-STL-DV-P-TR add compared to a standard tail surface-mount terminal strip?
The STL long-tail option extends the solder pin below the PCB mounting surface by a greater distance than a standard surface-mount tail, increasing the solder joint fillet area and improving mechanical pull strength. In applications where the 4-position dual-row connector is subject to cable tension or vibration, the longer tail distributes stress across more solder material on the 0.100-inch pitch pads, reducing the risk of joint fatigue fracture over the product lifespan.
How does the polarization (P) feature prevent miswiring when assembling boards with TSM-102-05-STL-DV-P-TR?
The polarization key is a physical notch or post on the connector housing that corresponds to a matching feature on the mating plug, allowing only one correct insertion orientation across the 4-position dual-row interface. On a 0.100-inch pitch connector this is particularly important because pin 1 and pin 4 are only 0.3 inches apart, making visual orientation difficult under production lighting. Polarization eliminates reversed insertions that would short power and ground lines on dual-voltage DV-configured boards.
In what production scenario does tape-and-reel packaging make TSM-102-05-STL-DV-P-TR more cost-effective than cut-strip packaging?
Tape-and-reel packaging is cost-effective when assembly volumes exceed roughly 500 units per production run, as it allows automated pick-and-place machines to place the 4-position 0.100-inch pitch connector without operator handling between each cycle. At lower volumes the per-unit premium for tape-and-reel over cut-strip may not be recovered by labor savings, but for consumer electronics or IoT device production in the thousands, TR packaging reduces cycle time per board by several seconds and nearly eliminates placement defects caused by manual loading.
