Frequently Asked Questions
How many total contacts does the TSM-143-03-H-DV-P-TR provide, and what is the row pitch?
The TSM-143-03-H-DV-P-TR provides 172 total contacts arranged as 86 positions in a dual-row layout at 0.100-inch (2.54 mm) pitch. This high contact count on the standard 2.54 mm grid supports wide parallel buses, dedicated power and ground pins, and control signal lines across a single SMT connector in backplane and industrial controller designs.
What current-carrying capacity does each contact in the TSM-143-03-H-DV-P-TR support?
Each contact is rated for 3 A of continuous current, allowing the TSM-143-03-H-DV-P-TR to simultaneously handle moderate power distribution alongside signal lines. With 172 contacts, dedicated power rows can carry up to 3 A each, enabling multi-rail supply routing for 5 V, 12 V, and 3.3 V planes on industrial backplane and server expansion card designs.
Is the TSM-143-03-H-DV-P-TR designed for automated SMT high-volume production?
Yes, the TR suffix identifies tape-and-reel packaging directly compatible with automated pick-and-place SMT equipment. The connector supports lead-free reflow soldering at peak temperatures up to 260°C per IPC/JEDEC J-STD-020, and its 2.54 mm pitch land pattern is available in standard PCB CAD library footprints, simplifying qualification for high-volume industrial and telecommunications PCB manufacturing.
What temperature range and mating-cycle life does the TSM-143-03-H-DV-P-TR provide for industrial deployments?
The TSM-143-03-H-DV-P-TR operates across -55°C to 125°C and is rated for a minimum of 500 mating cycles while maintaining gold-plated contact resistance below 20 mΩ. These specifications meet the reliability requirements for industrial motor control panels, military embedded computers, and telecommunications infrastructure hardware where connectors experience thermal cycling and periodic board removal over a 10 to 20 year service lifetime.
