Frequently Asked Questions
What is the contact pitch and row configuration of TSM-135-03-SS-DH-A-P-TR?
The TSM-135-03-SS-DH-A-P-TR uses a 2.54 mm (0.100 inch) pitch with a dual-row (DH) layout providing 70 total positions arranged as 2×35 pins, making it one of the higher-density options in the TSM series for surface mount board interconnects.
How much current can each contact in TSM-135-03-SS-DH-A-P-TR carry, and what contact material is used?
Each contact is rated at approximately 3 A current capacity. The contacts are made from stainless steel (SS designation) with gold plating, providing excellent corrosion resistance, low contact resistance, and reliable performance over thousands of mating cycles in demanding industrial environments.
Which packaging format does TSM-135-03-SS-DH-A-P-TR use, and how does it benefit high-volume PCB assembly?
The -TR suffix indicates tape-and-reel packaging, which delivers connectors on a continuous reel for automated pick-and-place SMT assembly equipment. This allows throughput rates well suited to high-volume production runs, reducing handling time compared to cut-strip packaging while maintaining 2.54 mm pitch placement accuracy.
When would TSM-135-03-SS-DH-A-P-TR be chosen over a through-hole equivalent for a backplane design?
For backplane designs where board thickness or rear clearance is constrained below 3 mm, the surface mount profile of TSM-135-03-SS-DH-A-P-TR eliminates through-hole drilling costs and allows double-sided component placement. The 70-pin SMT strip also reduces PCB layer count requirements compared to through-hole headers for 35+ signal backplane interfaces.
