The **QBLP600-RIG** is a specific Surface Mount Device (SMD) LED manufactured by **QT-Brightek**. It belongs to the 0603 package family, which is one of the most common sizes for indicator lights in consumer electronics. --- ## 1. Technical Specifications The "RIG" suffix typically denotes a **Red/Green/Blue (RGB)** or specific bi-color configuration, but in the standard QT-Brightek nomenclature for the 600 series, it often refers to a **Red and True Green** bi-color LED. | Parameter | Specification | | :--- | :--- | | **Package Size** | 0603 (1.6mm x 0.8mm) | | **LED Type** | Bi-Color (Red & True Green) | | **Forward Voltage (Vf) - Red** | 2.0V (Typical) | | **Forward Voltage (Vf) - Green** | 3.2V (Typical) | | **Luminous Intensity (Iv)** | Red: ~70 mcd / Green: ~200 mcd | | **Viewing Angle** | 140 Degrees | | **Lens Type** | Water Clear | --- ## 2. Pin Configuration and Internal Logic The QBLP600-RIG is a **Common Anode** or **Common Cathode** device (depending on the specific sub-variant), meaning two internal LED chips share one terminal to save space on the PCB. ### Schematic Representation ```text [Red Cathode] ----|<|---- [Common Anode] [Green Cathode] --|<|---- [Common Anode] ``` --- ## 3. Key Electronic Characteristics * **Wavelength:** * **Red:** ~624nm (Standard Bright Red) * **True Green:** ~525nm (Emerald/True Green, not the yellowish-green) * **Current Rating:** Designed for a standard **20mA** forward current ($I_f$). However, for modern high-efficiency displays, 5mA–10mA is often sufficient. * **SMT Compatibility:** Compatible with infrared (IR) reflow soldering processes. --- ## 4. Typical Applications Because of its small footprint and dual-color capability, this part is frequently used in: 1. **Status Indicators:** (e.g., Red for "Error," Green for "Power On"). 2. **Battery Charging Levels:** Shifting colors based on charge state. 3. **Backlighting:** Small buttons or membrane switches. 4. **Network Hardware:** Link/Activity lights on routers and modems. ---
