What are the key features of TSM-110-03-FM-DH-P-TR?
- 20-position dual-row SMT terminal strip with 0.100 inch (2.54 mm) pitch providing a standard footprint compatible with a wide range of mating receptacles
- Flush-mount (-FM) termination and polarized housing (-P) preventing mis-insertion and ensuring correct connector orientation during assembly and field replacement
- Tape-and-reel (-TR) packaging enabling automated pick-and-place placement for high-volume SMT production lines
What is TSM-110-03-FM-DH-P-TR used for?
The TSM-110-03-FM-DH-P-TR is designed for board-to-board and board-to-wire interconnect in industrial automation, test and measurement instruments, and embedded computing modules requiring dual-row 0.100 inch pitch connectivity. Its polarized housing eliminates the risk of reverse mating in multi-connector assemblies, reducing field wiring errors in control panels and instrumentation racks. The tape-and-reel format and SMT footprint support efficient automated assembly in high-volume consumer electronics and IoT gateway production.

Frequently Asked Questions
How does the polarized housing (-P) of the TSM-110-03-FM-DH-P-TR prevent mis-mating in multi-connector assemblies?
The polarized housing includes an asymmetric keying feature that physically blocks insertion of the mating connector in the wrong orientation. In assemblies with 4 or more connectors at 0.100 inch pitch placed within 5 mm of each other, this prevents accidental mis-wiring that could short power rails to signal lines, reducing field rework costs and protecting downstream circuits rated for less than 5 V logic levels.
What is the current-carrying capacity of each contact in the TSM-110-03-FM-DH-P-TR and how does this affect power rail assignment?
Each contact pin in the TSM-110-03-FM-DH-P-TR is typically rated for 2 A to 3 A at 30°C temperature rise, consistent with Samtec's standard TSM series. With 20 positions in a dual-row layout, designers can dedicate multiple pins to power rails, for example assigning 4 pins to a 5 V supply allows up to 8 A of power delivery while the remaining 16 pins carry signal lines.
Which scenarios make the TSM-110-03-FM-DH-P-TR preferable to a through-hole dual-row header of the same pitch?
The SMT version is preferable when the PCB uses a no-lead or leadless process such as reflow soldering, eliminating the need for a separate wave soldering step. It also allows components to be placed on both sides of the board within 1 mm of the connector location, a constraint that through-hole pins cannot satisfy. Additionally, the flush-mount termination reduces the connector's installed height to approximately 3 mm, enabling thinner product enclosures.
