The **QBLP613-RIG** is a high-performance, surface-mount (SMD) Light Emitting Diode (LED) manufactured by **QT-Brightek**. It belongs to the 0805 package family and is specifically designed for applications requiring a True Green output with high reliability. --- ### 1. Key Technical Specifications Below are the primary electronic and optical characteristics of the QBLP613-RIG: | Parameter | Specification | | :--- | :--- | | **LED Color** | True Green | | **Package Type** | 0805 (Metric 2012) | | **Luminous Intensity** | 250 mcd - 450 mcd (typical) | | **Dominant Wavelength** | 520 nm - 530 nm | | **Forward Voltage ($V_F$)** | 2.8V (min) - 3.7V (max) | | **Forward Current ($I_F$)** | 20 mA (Test Current) | | **Viewing Angle** | 140 Degrees | | **Lens Appearance** | Water Clear | --- ### 2. Physical Dimensions & Material The component is characterized by its compact footprint, making it ideal for high-density circuit boards. * **Size:** 2.0mm x 1.25mm x 0.8mm. * **Material:** InGaN (Indium Gallium Nitride) on Sapphire substrate. This material composition is responsible for the efficient "True Green" wavelength, which is more vibrant than standard "Yellow-Green" (GaP) LEDs. * **Termination:** Gold (Au) plating for excellent solderability and corrosion resistance. --- ### 3. Electronic Behavior and Usage To ensure the longevity of the QBLP613-RIG, specific electronic constraints must be observed: #### Absolute Maximum Ratings * **Reverse Voltage ($V_R$):** 5V (Maximum protection against back-flow). * **Peak Forward Current:** 100 mA (at 1/10 duty cycle, 0.1ms pulse width). * **Power Dissipation ($P_D$):** 75 mW - 110 mW depending on thermal conditions. * **Operating Temperature:** -40°C to +85°C. #### Recommended Circuit Implementation When integrating this LED into a circuit, a current-limiting resistor is mandatory. For a standard 5V supply: ```text R = (V_supply - V_forward) / I_forward R = (5V - 3.2V) / 0.02A R = 90 Ohms (Standard value: 100 Ohms) ``` --- ### 4. Common Applications * **Status Indicators:** Network routers, consumer electronics, and industrial panels. * **Backlighting:** Backlighting for LCDs, switches, and membrane keypads. * **Automotive:** Dashboard lighting and interior accents. * **Edge Lighting:** Decorative lighting in wearables or portable devices.
