Frequently Asked Questions
What does the CH=1.55mm dimension indicate in this Micro HDMI connector?
The center height (CH=1.55mm) defines the nominal vertical distance from the PCB surface to the geometric center line of the HDMI Type D mating interface, ensuring precise aperture alignment in thin enclosure designs.
What are the reflow soldering and material specifications for this SMT receptacle?
The connector housing is molded from high-temperature black LCP rated UL 94V-0, fully compatible with standard lead-free reflow profiles up to +85°C continuous operating temperatures.
What contact plating and mechanical durability ratings are specified?
The 19 contacts are stamped from C5191 phosphor bronze finished with 1 micro-inch gold plating over the contact area, ensuring 30 mΩ max contact resistance and 10,000 insertion/extraction cycles.
How does the dual-row SMT layout integrate with high-density PCB designs?
The dual-row surface-mount contact configuration maximizes pitch density while robust solder-down brass shell tabs anchor the receptacle directly to ground planes, providing mechanical strain relief.
Overview and Application Notes
