Key Features
- 18-position dual-row 0.100" (2.54 mm) pitch SMT terminal strip with 3A per pin contact rating for mixed signal and power routing
- Tall DH standoff height provides defined PCB clearance for component-under-connector placement in space-constrained assemblies
- Polarization peg (P) prevents mis-insertion and tape-and-reel (TR) packaging enables automated SMT pick-and-place assembly
Applications
The TSM-109-03-TL-DH-A-P-TR is used in compact control boards, evaluation kits, and embedded system expansion headers where 18 signals or power rails must be reliably routed at the standard 2.54 mm pitch. Its dual-row layout and DH tall standoff suit stackable modular designs in industrial I/O modules, robotics controllers, and test fixture boards requiring defined board-to-board clearance. The polarization peg prevents assembly errors in high-volume SMT production runs.

Frequently Asked Questions
What current rating and pin count does TSM-109-03-TL-DH-A-P-TR provide for power and signal distribution?
The TSM-109-03-TL-DH-A-P-TR offers 18 positions rated at 3A per pin at a 0.100" (2.54 mm) pitch. Adjacent pins can be ganged to carry higher currents; for example, combining 3 pins per power rail supports up to 9A per supply net. This makes it appropriate for dual-rail or multi-rail power distribution alongside digital signal lines in embedded control PCBs.
How does the DH tall-profile standoff in TSM-109-03-TL-DH-A-P-TR benefit PCB layout?
The DH designation specifies a taller-than-standard body height, creating additional clearance between the mated boards. This extra clearance—typically 3mm to 8mm depending on the SAMTEC series variant—allows placement of tall SMD components such as electrolytic capacitors or inductors directly beneath the connector footprint, improving component density on both PCBs in a stacked-board assembly.
For high-volume SMT production, how does the TR tape-and-reel format of TSM-109-03-TL-DH-A-P-TR improve assembly yield?
The TR (tape-and-reel) packaging of TSM-109-03-TL-DH-A-P-TR feeds each connector in a fixed, pre-oriented position on standard 24mm or 32mm carrier tape compatible with automated pick-and-place machines. This eliminates manual handling, reduces placement errors from incorrect orientation by over 99%, and supports high-speed SMT assembly lines running at thousands of placements per hour for 18-position dual-row connectors.
