Frequently Asked Questions
What is the stack height and pin count of the LSHM-140-04.0-L-DV-A-N-K-TR, and how does this affect board spacing?
The LSHM-140-04.0-L-DV-A-N-K-TR provides a 4.0 mm board-to-board stack height and 40 positions in its hermaphroditic configuration, allowing two PCBs to be precisely separated by 4.0 mm while maintaining 40 reliable signal paths for high-density stacked designs.
Which signal applications benefit from the dual-voltage differential (DV) feature of this SAMTEC connector?
The dual-voltage differential capability of this connector supports high-speed differential pairs operating at data rates exceeding 10 Gbps, making it well suited for FPGA mezzanine cards, PCIe expansion boards, and high-speed ADC interface modules where signal integrity across the 4.0 mm stack gap is critical.
Is the LSHM-140-04.0-L-DV-A-N-K-TR compatible with automated SMT assembly lines?
Yes, the -TR suffix indicates tape-and-reel packaging with reels containing components in standardized carrier tape, fully compatible with pick-and-place machines and reflow soldering at temperatures up to 260°C, making it suitable for high-volume SMT production with typical factory lead times of 1 week.
What contact finish does the LSHM-140-04.0-L-DV-A-N-K-TR use, and why does it matter for reliability?
The connector uses tin-over-nickel finish on mating contacts and tin with nickel barrier on termination contacts, providing a corrosion-resistant surface that maintains contact resistance below specified limits across operating temperature ranges and repeated mating cycles in industrial and telecom environments.
