Frequently Asked Questions
What does the H0.80mm mid-mount sinking design achieve in PCB layout?
The H0.80 sinking configuration lowers the connector body 0.80mm into a pre-routed 11.70mm PCB cutout. This reduces the vertical clearance above the board to approximately 1.70mm, optimizing ultra-slim device enclosures while preserving signal integrity.
What are the recommended PCB thickness and solder pad specifications?
Recommended PCB thickness ranges from 1.00mm to 1.20mm. SMT signal pads require a 0.40mm center pitch with a 0.25mm pad width, while 4 plated through-holes (1.25mm x 0.75mm and 1.80mm x 2.30mm slots) anchor the shell legs against mechanical stress.
How do the contact and shell plating materials ensure electrical reliability?
Both copper alloy signal pins and shell are manufactured with selective gold plating over a precision base alloy, ensuring contact resistance remains below 30 mΩ and providing high corrosion protection across 5,000 mating cycles.
Is this connector suitable for harsh industrial operating environments?
Yes. Constructed with an LCP UL 94V-0 thermoplastic housing and a copper alloy shell, it operates across a wide temperature range of -55°C to +105°C with 500V AC dielectric withstand rating.
Overview and Application Notes
The Mini HDMI Type C female receptacle is engineered with an SMT contact interface and a sinking mid-mount configuration featuring a 0.80mm below-board offset and 4 through-hole shell mounting legs for reinforced mechanical retention. Built with a neutral shell without embossed logos, it delivers high-integrity digital audio-video transmission in low-profile embedded systems, compact portable devices, and density-critical PCB layouts.
Key Features
- Form Factor & Pin Count: 19-position Mini HDMI Type C female receptacle adhering to standard digital signal assignments.
- Mid-Mount Architecture: 0.80mm sinking height (H0.80) to significantly lower the overall profile above the PCB surface.
- Robust Retention: 4 shell dip-soldering legs with a rear locator peg offset (1.50mm) for superior anti-torsion and drop-shock stability.
- High-Temperature Housing: High-grade LCP thermoplastic (UL 94V-0, Black) compatible with lead-free reflow soldering.
- Premium Contact Finish: Copper alloy terminals finished with selective gold plating to ensure low contact resistance and corrosion resistance.
- Endurance: Rated for a minimum of 5,000 mating cycles across an operating range of -55°C to +105°C.
Engineering Specifications & PCB Integration
The connector requires a board cut-out width of 11.70mm to accommodate the mid-mount sinking body, with an outer shell footprint pitch of 14.00mm. Signal pads are spaced at a precision 0.40mm center-to-center pitch with recommended pad widths of 0.25mm. Recommended PCB thickness is 1.00mm to 1.20mm. The 4 solder tines ensure high-reliability ground grounding and mechanical latching during repeated cable insertion.
