Based on the product code provided, the **HDMI-MM-RASU-3M** typically refers to a specialized **HDMI Male-to-Male (MM) Right-Angle (RA) Super-Ultra (SU) 3-Meter (3M)** cable. Below is an explanation of its electronic components and specifications. --- ### 1. Technical Specifications Breakdown | Component | Description | | :--- | :--- | | **Connector Type** | Dual HDMI Type A (Male) | | **Form Factor** | Right-Angle (90 degree) connector on one or both ends | | **Length** | 3.0 Meters (approx. 9.8 feet) | | **Wire Gauge** | Typically 30 AWG to 34 AWG (Ultra-thin series) | | **Bandwidth** | Supports up to 18Gbps (HDMI 2.0 standards) | | **Resolution Support** | 4K @ 60Hz, UHD, 1080p, and 3D Video | --- ### 2. Key Electronic Components #### A. Internal Wiring (Conductors) The cable consists of multiple twisted pairs of high-purity oxygen-free copper (OFC). * **TMDS Channels:** Transition Minimized Differential Signaling channels carry the high-speed video and audio data. * **DDC (Display Data Channel):** Used for the handshake between the source (e.g., PC) and the display (e.g., Monitor) to exchange EDID information. #### B. Shielding Layers To prevent Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI), these cables utilize: 1. **Individual Foil Shielding:** Wrapped around each twisted pair. 2. **Overall Braid Shielding:** A conductive mesh that surrounds all internal wires. 3. **Drain Wire:** A non-insulated wire that grounds the shield to the connector shells. #### C. Connector Construction * **Gold-Plating:** The pins and shells are usually 24K gold-plated to ensure low contact resistance and prevent oxidation/corrosion over time. * **Right-Angle PCB/Leadframe:** Unlike straight cables, the right-angle version uses a compact internal leadframe to redirect the signals 90 degrees without causing signal reflection or impedance mismatch. --- ### 3. Structural Features * **Ultra-Thin Jacket (SU Series):** The "Super-Ultra" designation usually refers to a high-flexibility, small-diameter PVC or TPE jacket. This makes it ideal for tight spaces behind wall-mounted TVs or inside gimbal setups. * **Strain Relief:** Molded plastic transitions that prevent the internal wires from snapping when the cable is bent at the connector junction. ---
