The **MH11FDG-R** is an ultra-small, high-performance **Micro-HDMI (Type D) Connector**. It is commonly utilized in compact electronic devices that require high-definition video and audio output. --- ## 1. Component Specifications The MH11FDG-R is designed for high-speed data transmission while maintaining a minimal physical footprint. | Feature | Specification | | :--- | :--- | | **Connector Type** | Micro HDMI (Type D) | | **Orientation** | Right Angle (Horizontal) | | **Mounting Type** | Surface Mount (SMT) | | **Number of Contacts** | 19 Pins | | **Shielding** | Full Metal Shield for EMI/RFI Protection | | **Current Rating** | 0.5A per contact | | **Contact Plating** | Gold (typically 15μ" or 30μ") | --- ## 2. Key Electronic Characteristics ### High-Speed Data Transfer This component is engineered to handle **HDMI 1.4 and HDMI 2.0** standards. It supports: * **Ethernet Channel:** Integrated data channel for networking. * **Audio Return Channel (ARC):** Allows audio to be sent "upstream" to an AV receiver. * **4K Resolution:** Capability to transmit high-definition signals at high refresh rates. ### Mechanical Integrity * **Durability:** Usually rated for **5,000 to 10,000 mating cycles**, making it suitable for consumer electronics that are frequently plugged/unplugged. * **Shell Design:** Features a robust metal shell with grounding tabs to ensure a stable electrical connection and reduce noise interference. --- ## 3. PCB Layout Considerations When integrating the MH11FDG-R into a circuit design, engineers must pay close attention to the footprint: ```markdown 1. Signal Integrity: Differential pairs (TMDS) must be routed with 100Ω impedance. 2. Grounding: All shell tabs should be soldered to a solid ground plane. 3. Clearance: Due to the high density of the 19 pins, ensure minimum solder bridge risk. ``` --- ## 4. Common Applications Because of its "Micro" form factor, it is found in: * **Action Cameras:** (e.g., GoPro and similar devices). * **Smartphones & Tablets:** For direct TV output. * **Single Board Computers (SBCs):** Such as the Raspberry Pi 4 (which uses Micro-HDMI). * **Portable Medical Monitors:** Where space is at a premium.
