What are the key features of TSM-115-03-FM-DH-A-K-TR?
- 30-position dual-row terminal strip on a 0.100 inch (2.54 mm) pitch for standard industrial and embedded board interfaces
- 3 mm post height (option 03) provides compatible mating depth with standard 0.100 inch receptacle housings and wire-to-board assemblies
- Kinked (K) SMT tail creates a controlled solder standoff for improved joint quality and post-reflow optical inspection
- Tape-and-reel (TR) packaging supports automated pick-and-place processes on high-volume SMT production lines
What is TSM-115-03-FM-DH-A-K-TR used for?
The TSM-115-03-FM-DH-A-K-TR suits embedded computing modules, industrial control backplanes, and test-and-measurement instrumentation that require a 30-position 2.54 mm pitch SMT terminal strip with a 3 mm mating post. Its dual-row layout maximizes contact density while the kinked tail and tape-and-reel packaging streamline high-volume surface mount assembly in electronics manufacturing.

Frequently Asked Questions
What distinguishes the TSM-115-03-FM-DH-A-K-TR from the TSM-115-01-F-DH-A-K-TR in terms of post height?
The '03' in the TSM-115-03-FM-DH-A-K-TR specifies a 3 mm post height above the PCB surface, compared to the shorter post of the '-01' variant. The taller 3 mm post depth is compatible with deeper receptacle housings and wire-to-board connectors, giving designers more flexibility in connector pairing for the 30-position 2.54 mm pitch interface.
How does the kinked tail on the TSM-115-03-FM-DH-A-K-TR improve SMT solder reliability?
The kinked (K) tail lifts the connector body slightly above the PCB pads during reflow soldering, creating a controlled standoff across all 30 positions. This allows flux vapor to escape and ensures solder wets the full pad contact area, improving joint strength and making the 2.54 mm pitch solder joints accessible for automated optical inspection.
For a 30-pin dual-row 2.54 mm pitch SMT interface, when would a designer choose the FM contact finish option?
The FM (flash gold over nickel) contact finish provides a thin gold layer over nickel barrier, offering moderate oxidation resistance at a lower cost than full gold plating. Designers choose FM finish for the TSM-115-03-FM-DH-A-K-TR when environmental exposure is moderate and the 30-position connector will undergo fewer than several hundred mating cycles in industrial or instrumentation applications.
Is the TSM-115-03-FM-DH-A-K-TR suitable for high-volume automated assembly, and how is it packaged for production?
Yes, the TR suffix indicates tape-and-reel packaging, making the TSM-115-03-FM-DH-A-K-TR fully compatible with automated pick-and-place equipment. The reel format supports uninterrupted high-volume SMT line runs, and the kinked K tail simplifies solder inspection for all 30 positions across the 0.100 inch dual-row footprint.
