### MV68V3CG-R Electronic Overview The **MV68V3CG-R** is a specific part number typically associated with **SMD (Surface Mount Device) LEDs**, specifically categorized under high-efficiency, small-footprint optoelectronics. It is often manufactured by companies like **Everlight** or **Lite-On**, though the "MV" prefix is a common industry indicator for Miniature/AlGaAs (Aluminum Gallium Arsenide) technology. --- ### Technical Specifications | Parameter | Specification (Typical) | | :--- | :--- | | **Component Type** | SMD LED (Light Emitting Diode) | | **Package Type** | 0603 (1608 Metric) | | **Emitted Color** | Super Bright Red | | **Material** | AlGaInP (Aluminum Gallium Indium Phosphide) | | **Forward Voltage ($V_f$)** | 1.8V to 2.4V | | **Luminous Intensity** | 30 - 80 mcd @ 20mA | | **Viewing Angle** | 120° to 130° | | **Wavelength** | ~630nm - 640nm (Dominant) | --- ### Key Internal Components 1. **Semiconductor Die:** The core "chip" made of AlGaInP. When current flows from the anode to the cathode, electrons recombine with holes, releasing energy in the form of red light. 2. **Epoxy/Resin Lens:** The "CG" in the suffix often denotes a **Water Clear** lens, allowing for maximum light transmission without diffusion. 3. **Lead Frame/Substrate:** A ceramic or PCB-based substrate that provides mechanical support and electrical connectivity. 4. **Gold Wire Bond:** A microscopic wire connecting the semiconductor die to the external electrodes. --- ### Circuit Integration To use this component in a circuit, a current-limiting resistor is mandatory to prevent thermal runaway. #### Example Calculation: If using a 5V power supply: ```text R = (V_source - V_forward) / I_forward R = (5V - 2.0V) / 0.02A (20mA) R = 150 Ohms ``` --- ### Common Applications * **Status Indicators:** Power LEDs on consumer electronics. * **Backlighting:** Small LCD screens or button illumination. * **Wearables:** Due to the compact 0603 footprint. * **Automotive:** Dashboard indicators and instrument clusters.
