Frequently Asked Questions
What stacking height and pitch does the LSHM-140-02.5-F-DV-A-S-K-TR provide for board-to-board designs?
The LSHM-140-02.5-F-DV-A-S-K-TR offers a 2.5 mm board stacking height on a fine 0.50 mm pitch with 80 total positions, making it ideal for compact stacked-module designs where minimizing the vertical gap between boards is critical for system height constraints.
How does the shielded hermaphroditic contact type of the LSHM-140-02.5-F-DV-A-S-K-TR benefit high-speed signal applications?
The shielded hermaphroditic design of the LSHM-140-02.5-F-DV-A-S-K-TR provides continuous EMI shielding around all 80 signal contacts, reducing crosstalk and radiated emissions at data rates exceeding 10 Gbps, which is particularly valuable in high-speed serial interfaces on compact mezzanine or wireless communication modules.
What does the K suffix in LSHM-140-02.5-F-DV-A-S-K-TR indicate, and how does it affect PCB assembly?
The K suffix in LSHM-140-02.5-F-DV-A-S-K-TR designates a peg board mounting option, meaning the connector includes integrated alignment pegs that engage the PCB during SMT reflow, preventing movement across all 80 positions and improving coplanarity and solder joint reliability in automated assembly processes.
