## HLMP-CW11-RVB00: Technical Specifications & Overview The **HLMP-CW11-RVB00** is a high-brightness, T-1 ¾ (5mm) precision optical performance white LED manufactured by Broadcom (formerly Avago Technologies). It is designed for applications requiring high light output and a wide viewing angle. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **LED Type** | Standard Through-Hole | | **Color** | Cool White | | **Package Size** | T-1 ¾ (5mm) | | **Luminous Intensity** | 1500 mcd to 4200 mcd | | **Viewing Angle** | 15° | | **Forward Voltage ($V_f$)** | 3.2V (Typical) to 4.0V (Max) | | **Forward Current ($I_f$)** | 30mA (Max) | | **Operating Temperature** | -40°C to +80°C | | **Lens Appearance** | Water Clear | --- ### 2. Physical Construction The HLMP-CW11 series utilizes **InGaN** (Indium Gallium Nitride) chip technology. * **Encapsulation:** The LED is housed in an epoxy resin that contains UV inhibitors to reduce long-term degradation when exposed to direct sunlight. * **Form Factor:** It features a standard radial lead design (anode and cathode pins) suitable for PCB mounting or panel indicators. --- ### 3. Part Number Breakdown (RVB00 suffix) The suffix provides specific information regarding the binning of the component: * **R:** Minimum Luminous Intensity Bin. * **V:** Maximum Luminous Intensity Bin. * **B:** Color Bin (Cool White spectrum). * **00:** Standard packaging/No special modifications. --- ### 4. Typical Applications Due to its high intensity and narrow viewing angle (15°), this part is commonly used in: 1. **Electronic Signs and Signals:** Variable message signs and solar-powered traffic signals. 2. **Commercial Outdoor Advertising:** Backlighting for displays. 3. **Industrial Equipment:** Status indicators that need to be visible in high-ambient light environments. 4. **Flashlights/Torches:** As a primary light source for portable devices. --- ### 5. Design Considerations * **Current Limiting:** A resistor must be used in series to prevent thermal runaway, as $V_f$ decreases as temperature increases. * **Polarity:** The longer lead is typically the Anode (+), and the shorter lead/flat side of the housing is the Cathode (-). * **Heat Dissipation:** While 30mA is the maximum rating, running the LED at 20mA is recommended for prolonged life and stability.
