Key Features
- 6 positions in dual-row 0.100" (2.54 mm) pitch SMT configuration providing 3 contacts per row in a compact footprint
- Gold-plated contacts (-K) ensure contact resistance below 20 mΩ and reliable long-term signal integrity
- Surface mount termination compatible with standard reflow soldering at peak temperatures up to 260°C
- Tape-and-reel (-TR) packaging enables automated pick-and-place assembly for efficient high-volume SMT production
Applications
The TSM-103-03-F-DH-A-K-TR is used in compact PCB designs requiring a small 6-position dual-row SMT connector for power and signal distribution in embedded modules, sensor interface boards, and prototype evaluation cards. Its 0.100" pitch and gold contacts make it suitable for low-noise analog signal routing and digital I/O connections in industrial instruments and consumer electronics. The tape-and-reel packaging supports automated assembly in high-volume production of small form-factor boards and IoT devices.

Frequently Asked Questions
What position count and row layout does the TSM-103-03-F-DH-A-K-TR offer for compact SMT designs?
The TSM-103-03-F-DH-A-K-TR provides 6 total positions in a dual-row (DH) configuration at 0.100" (2.54 mm) pitch, with 3 contacts per row. This small footprint connector is well-suited for compact embedded modules, sensor interface boards, and evaluation cards where only 6 power or signal connections are needed in a minimal PCB area.
How does the gold contact plating on the TSM-103-03-F-DH-A-K-TR compare to tin-plated alternatives for low-signal applications?
The -K suffix specifies gold-plated contacts, which maintain contact resistance below 20 mΩ and resist oxidation that can degrade tin-plated contacts over time in humid environments. For low-level analog signal connections below 100 mV or high-frequency digital interfaces where even small increases in contact resistance affect signal quality, gold plating provides superior and more consistent performance over the connector's service life compared to tin-plated alternatives.
Which scenarios make a 6-position dual-row connector like the TSM-103-03-F-DH-A-K-TR preferable to two 3-pin single-row connectors?
A single 6-position dual-row connector like the TSM-103-03-F-DH-A-K-TR reduces BOM complexity by consolidating two separate 3-pin connectors into one component, lowering placement cycle time and eliminating the risk of mismating separate connectors during board assembly or field service. The dual-row arrangement also provides a more mechanically stable connection than two side-by-side single-row connectors, which is important on boards subject to vibration in industrial or automotive applications.
What does the -TR suffix on the TSM-103-03-F-DH-A-K-TR indicate and why is it important for production?
The -TR suffix indicates tape-and-reel packaging, where connectors are pre-loaded into a carrier tape on a standard reel for use with automated pick-and-place equipment. This packaging format ensures consistent component orientation, eliminates manual loading time, and is compatible with standard SMT feeders at reel pitches used for 0.100" connectors, making it essential for high-throughput automated assembly lines producing boards at rates of thousands of units per shift.
