What are the key features of TSM-103-04-F-DH-A-K-TR?
- 6-position dual-row layout on 0.100" (2.54 mm) pitch delivering a compact, low-pin-count SMT header in a standard grid footprint
- Gold-plated contacts rated at 3 A per pin supporting mixed signal and moderate power routing within a single 6-pin connector
- Tape-and-reel (TR) packaging ensuring compatibility with automated SMT pick-and-place equipment for high-volume assembly
- Dual-height (DH) SMT design providing increased stand-off for improved solder joint inspection and rework access
What is TSM-103-04-F-DH-A-K-TR used for?
The TSM-103-04-F-DH-A-K-TR is used as a compact 6-position board-to-board or daughter-card header in IoT devices, embedded controllers, and consumer electronics where a standard 0.100" dual-row pitch SMT connector is required. Its 3 A per pin rating makes it suitable for combining GPIO signals and low-power supply connections in a single compact footprint. The tape-and-reel format supports automated high-volume reflow assembly, reducing per-unit labor cost in mass production environments.

Frequently Asked Questions
How much total current can the TSM-103-04-F-DH-A-K-TR carry, and how does pin count affect power distribution?
The TSM-103-04-F-DH-A-K-TR has 6 positions each rated at 3 A, giving a maximum combined capacity of 18 A across all 6 pins. In practice, designers derate by 20-30% at temperatures above 70°C, limiting reliable total throughput to approximately 12-14 A. For a 5 V microcontroller interface, this allows up to 2 pins to carry power with 4 pins reserved for signal, well within the connector's current budget.
What does the dual-height DH suffix indicate on the TSM-103-04-F-DH-A-K-TR, and why does it matter for SMT rework?
The DH suffix designates a dual-height SMT terminal strip, meaning the connector body stands off the PCB surface by an increased height compared to standard-profile variants. This added clearance—typically 1 to 2 mm above the PCB surface—allows soldering iron tips and hot-air nozzles better access during manual rework of the 6 solder joints, reducing the risk of lifting adjacent pads or heating neighboring components during repair operations.
For a compact 6-pin power and signal interface on an IoT sensor board, how does the TSM-103-04-F-DH-A-K-TR's 0.100" pitch compare to a 0.050" pitch alternative?
The TSM-103-04-F-DH-A-K-TR on 0.100" (2.54 mm) pitch occupies approximately twice the linear length of a 6-pin 0.050" (1.27 mm) pitch connector, but it supports 3 A per pin compared to the 1 A typical for 0.050" pitch variants. For an IoT sensor board needing 1-2 power pins at up to 3 A alongside 4 GPIO signals, the 0.100" pitch is the better choice without requiring separate power connectors.
What SAMTEC mating headers are compatible with the TSM-103-04-F-DH-A-K-TR in a standard PCB-to-PCB stack?
The TSM-103-04-F-DH-A-K-TR mates with SAMTEC's TSW or TSM series 6-position dual-row male headers on the 0.100" (2.54 mm) pitch. These mating headers are available in through-hole and SMT variants with stack heights from 4 mm to 15 mm, enabling flexible board separation in compact embedded modules. The 6-pin count and 2.54 mm pitch are also mechanically compatible with many industry-standard dual-row male headers from other manufacturers.
