The **HLMP-CE30-RUCDD** is a high-intensity, precision optical performance LED manufactured by Broadcom (formerly Avago Technologies). It belongs to the T-1¾ (5mm) through-hole LED family, specifically designed for applications requiring high brightness and a well-defined radiation pattern. --- ## 1. Technical Specifications The following table outlines the key electronic and optical characteristics of the HLMP-CE30-RUCDD: | Parameter | Specification | | :--- | :--- | | **Color** | Cyan (Blue-Green) | | **Dominant Wavelength** | 505 nm (Typical) | | **Luminous Intensity** | 1,500 mcd to 5,500 mcd | | **Viewing Angle** | 30° | | **Forward Current ($I_F$)** | 30 mA (Max) | | **Forward Voltage ($V_F$)** | 3.2V (Typical) / 4.0V (Max) | | **Lens Shape** | T-1¾ (5mm) Round | | **Lens Finish** | Clear, Non-diffused | | **Mounting Type** | Through-Hole | --- ## 2. Key Component Features The "RUCDD" suffix refers to specific binning and packaging configurations. Here are the core electronic aspects: ### A. Material Technology This LED uses **InGaN (Indium Gallium Nitride)** technology. InGaN is highly efficient for generating shorter wavelengths (blue, green, and cyan) and offers excellent stability across varying temperatures. ### B. Optical Precision * **Radiation Pattern:** The 30-degree viewing angle is achieved through a precision-molded epoxy lens. This makes it ideal for directional lighting rather than wide-area illumination. * **Color Consistency:** The part is binned for both intensity and color to ensure uniformity when multiple LEDs are used in an array. ### C. Electrical Safety * **ESD Sensitivity:** Like most InGaN devices, this LED is sensitive to static electricity. It typically has a Class 1C HBM (Human Body Model) rating. * **Power Dissipation:** It is rated for roughly 120mW of power dissipation, requiring careful resistor selection to avoid thermal runaway. --- ## 3. Typical Applications Due to its specific cyan color and high intensity, this part is commonly used in: 1. **Traffic Signaling:** Pedestrian "Walk" signs or specific nautical signals. 2. **Commercial Displays:** Full-color signs and variable message signs. 3. **Industrial Instrumentation:** Status indicators that require high visibility in sunlight. 4. **Specialized Lighting:** Decorative lighting where a specific 505nm hue is required. ---
